Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14313 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems.
This second edition cancels and replaces the first edition (ISO 14313:1999), which has been technically
revised, principally by the following.
Clause 2, on the requirements for conformity to this International Standard, has been added for
clarification.
Clause 7, on the requirements for allowable stresses and allowable deflection on design, has been
revised and clarified.
Clause 8, on material, has been revised to align the requirements with global industry practice for carbon
content and carbon equivalent for pressure-containing, pressure-controlling, welding ends and parts
requiring welding.
New requirements on repairs and NDE of welding repairs have been added to Clause 9 on Welding.
A new table (Table D.2) has been added to Annex D (informative) to provide more guidance for those
requirements listed in the text as requiring agreement between the manufacturer/purchaser.

Introduction
This International Standard is the result of harmonizing the requirements of ISO 14313:1999 and
API Spec 6D-2002[5].
The revision of ISO 14313 is developed based on input from both ISO/TC67/SC2 WG2 and
API 6D TG technical experts. The technical revisions have been made In order to accommodate the needs of
industry and to move this International Standard to a higher level of service to the petroleum and natural gas
industry.
Users of this International Standard should be aware that further or differing requirements can be needed for
individual applications. This International Standard is not intended to inhibit a manufacturer from offering, or
the purchaser from accepting, alternative equipment or engineering solutions for the individual application.
This may be particularly applicable where there is innovative or developing technology. Where an alternative
is offered, the manufacturer should identify any variations from this International Standard and provide details.

INTERNATIONAL STANDARD ISO 14313:2007(E)
© ISO 2007 – All rights reserved 1
Petroleum and natural gas industries — Pipeline transportation
systems — Pipeline valves
1 Scope
This International Standard specifies requirements and provides recommendations for the design,
manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline
systems meeting the requirements of ISO 13623 for the petroleum and natural gas industries.
This International Standard is not applicable to subsea pipeline valves, as they are covered by a separate
International Standard (ISO 14723).
This International Standard is not applicable to valves for pressure ratings exceeding PN 420 (Class 2 500).
2 Conformance
2.1 Units of measurement
In this International Standard, data are expressed in both SI units and USC units. For a specific order item,
unless otherwise stated, only one system of units shall be used, without combining data expressed in the
other system.
For data expressed in SI units, a comma is used as the decimal separator and a space is used as the
thousands separator. For data expressed in USC units, a dot (on the line) is used as the decimal separator
and a comma is used as the thousands separator.
2.2 Rounding
Except as otherwise required by this International Standard, to determine conformance with the specified
requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of
figures used in expressing the limiting value, in accordance with the rounding method of ISO 31-0:1992,
Annex B, Rule A.
2.3 Compliance to standard
A quality system should be applied to assist compliance with the requirements of this International Standard.
NOTE ISO/TS 29001 gives sector-specific guidance on quality management systems.
The manufacturer shall be responsible for complying with all of the applicable requirements of this
International Standard. It shall be permissible for the purchaser to make any investigation necessary in order
to be assured of compliance by the manufacturer and to reject any material that does not comply.

6.1.3 Ball valves
Typical configurations for ball valves with flanged or welding ends are shown, for illustration purposes only, in
Figures 4, 5 and 6.
Ball valves shall have a spherical obturator that rotates on an axis perpendicular to the direction of flow.
6.1.4 Check valves
Typical configurations for check valves are shown, for illustration purposes only, in Figures 7 to 13. Check
valves can also be of the wafer, axial flow and lift type.
Check valves shall have an obturator which responds automatically to block fluid in one direction.
6.2 Valve configurations
6.2.1 Full-opening valves
Full-opening flanged-end valves shall be unobstructed in the fully opened position and shall have an internal
bore as specified in Table 1. There is no restriction on the upper limit of valve bore sizes.
Full-opening through-conduit valves shall have a circular bore in the obturator that allows a sphere to pass
with a nominal size not less than that specified in Table 1.
Welding-end valves can require a smaller bore at the welding end to mate with the pipe.
Valves with a non-circular opening through the obturator shall not be considered full opening.
6.2.2 Reduced-opening valves
Reduced-opening valves with a circular opening through the obturator shall be supplied with a minimum bore
as follows, unless otherwise specified:
valves DN 300 (NPS 12) and below: one size below nominal size of valve with bore according to Table 1;
valves DN 350 (NPS 14) to DN 600 (NPS 24): two sizes below nominal size of valve with bore according
to Table 1;
valves above DN 600 (NPS 24): by agreement.
EXAMPLE A DN 400 (NPS 16) – PN 250 (class 1500) reduced-opening ball valve has a minimum bore of 287 mm.
Reduced-opening valves with a non-circular opening through the obturator shall be supplied with a minimum
opening by agreement.

The allowable stress values shall be consistent with the selected design code or standard.
If the selected design code or standard specifies a test pressure less than 1,5 times the design pressure, then
the design pressure for the body calculation shall be increased such that the hydrostatic test pressure in 11.3
can be applied.
NOTE 2 Some design codes or standards require a consistent and specific application of requirements for fabrication
and testing, including NDE.
7.2 Pressure and temperature rating
The nominal pressure (PN) class or the ASME rating class shall be used for the specification of the required
pressure class.
Valves covered by this International Standard shall be furnished in one of the following classes:
PN 20 (class 150);
PN 50 (class 300);
PN 64 (class 400);
PN 100 (class 600);
PN 150 (class 900);
PN 250 (class 1500);
PN 420 (class 2500).
Pressure-temperature ratings for class-rated valves shall be in accordance with the applicable rating table for
the appropriate material group in ASME B16.34.
Pressure-temperature ratings for PN-rated valves shall be in accordance with the applicable rating table for
the appropriate material group in EN 1092-1.
If intermediate design pressures and temperatures are specified by the purchaser, the pressure-temperature
rating shall be determined by linear interpolation.
Pressure-temperature ratings for valves made from materials not covered by ASME B16.34 and EN 1092-1
shall be determined from the material properties in accordance with the applicable design standard.
NOTE Non-metallic parts can limit maximum pressures and minimum and maximum operating temperatures.
The maximum operating pressure at the minimum and maximum operating temperatures shall be marked on
the nameplate.
7.3 Sizes
Valves constructed to this International Standard shall be furnished in nominal sizes as listed in Table 1.
NOTE In this International Standard, DN sizes are stated first followed by the equivalent NPS size between brackets.
Except for reduced-opening valves, valve sizes shall be specified by the nominal sizes (DN) or nominal pipe
size (NPS).
Reduced-opening valves with a circular opening shall be specified by the nominal size of the end connections
and the nominal size of the reduced opening in accordance with Table 1.

EXAMPLE 1 A DN 400 – PN 20 valve with a reduced 303 mm diameter circular opening shall be specified as
DN 400 (NPS 16) DN 300 (NPS 12).
Reduced-opening valves with a non-circular opening and reduced-opening check valves shall be designated
as reduced-bore valves and specified by the nominal size corresponding to the end connections followed by
the letter “R”.
EXAMPLE 2 Reduced-bore valve with DN 400 (NPS 16) end connections and a 381 mm 305 mm rectangular
opening shall be specified as 400R.
7.4 Face-to-face and end-to-end dimensions
Unless otherwise agreed, face-to-face (A) and end-to-end (B and C) dimensions of valves shall be in
accordance with Tables 2 to 6; see Figures 1 to 13 for diagrams of dimensions A, B and C.
Face-to-face and end-to-end dimensions for valve sizes not specified in Tables 2 to 6 shall be in accordance
with ASME B16.10. Face-to-face and end-to-end dimensions not shown in Table 2 to Table 6 or in
ASME B16.10 shall be established by agreement.
The length of valves having one welding end and one flanged end shall be determined by adding half the
length of a flanged-end valve to half the length of a welding-end valve.
Tolerances on the face-to-face and end-to-end dimensions shall be 2 mm for valve sizes DN 250 (NPS 10)
and smaller, and 3 mm for valve sizes DN 300 (NPS 12) and larger.
The nominal size and face-to-face or end-to-end dimensions shall be stated on the nameplate if not specified
in, or not in accordance with, Tables 2 to 6.

7.5 Valve operation
The purchaser should specify the method of operation and the maximum pressure differential (MPD) at which
the valve is required to be opened by the lever, gearbox or actuator. If not specified, the pressure as
determined in accordance with 7.2 for material at 38 °C (100 °F) shall be the MPD.
The manufacturer shall provide the following data to the purchaser, if requested:
flow coefficient C
v or K
v;
breakaway thrust or torque for new valve;
maximum allowable stem thrust or torque on the valve and, if applicable, the maximum allowable input
torque to the gearbox;
number of turns for manually operated valves.

7.6 Pigging
The purchaser shall specify the requirements for piggability of the valves.
NOTE Guidance can be found in Clause D.4.
7.7 Valve ends
7.7.1 Flanged ends
7.7.1.1 General
Flanges shall be furnished with a raised face or ring joint face (raised face or full face). Dimensions,
tolerances and finishes, including drilling templates, flange facing, spot facing and back facing, shall be in
accordance with
ASME B16.5 for sizes up to and including DN 600 (NPS 24), except DN 550 (NPS 22),
MSS SP-44 for DN 550 (NPS 22) and
ASME B16.47, Series A, for DN 650 (NPS 26) and larger sizes.
If none of the above standards applies, the selection of another design code or standard shall be made by
agreement.
The manufacturing method shall ensure flange alignment in accordance with 7.7.1.2, 7.7.1.3 and 7.7.1.4.
7.7.1.2 Offset of aligned flange centrelines — Lateral alignment
For valves up to and including DN 100 (NPS 4), the maximum flange misalignment shall be 2 mm (0.079 in).
For valves larger than DN 100 (NPS 4), the maximum flange misalignment shall be 3 mm (0.118 in).
7.7.1.3 Parallelism of aligned flange faces — Angular alignment
The maximum measured difference between flanges shall be 2,5 mm/m (0.03 in/ft).
7.7.1.4 Total allowable misalignment of bolt holes
For valves up to and including DN 100 (NPS 4), the maximum total allowable mismisalignment shall be no
greater than 2 mm (0.079 in) at the bolt holes (see Figure 14).
For valves larger than DN 100 (NPS 4), the maximum total allowable misalignment shall be equivalent to
3 mm (0.118 in) at the bolt holes.
The surface finish of the nut bearing area at the back face of flanged valves shall be parallel to within 1° of the
flange face.

7.7.2 Welding ends
Welding ends shall conform to ASME B31.4-2006, Figures 434.8.6 (a) (1) and (2) or ASME B31.8-2003,
Figures 14 and 15, unless otherwise agreed. In the case of a heavy-wall valve body, the outside profile may
be tapered at 30° and then to 45° as illustrated in ASME B16.25-2003, Figure 1.
The purchaser shall specify the outside diameter, wall thickness, material grade, SMYS and any special
chemistry of the mating pipe, and whether cladding has been applied.
7.7.3 Alternate valve end connections
Other end connections can be specified by the purchaser.
7.8 Pressure relief
The manufacturer shall determine whether fluid can become trapped in the body cavity in the open- and/or
closed-valve position.
If fluid trapping is possible, then valves for liquid or condensing service shall be provided with automatic
cavity-pressure relief, unless otherwise agreed. Automatic cavity relief arrangements for gas service shall be
provided by agreement.
Cavity relief, if required, shall prevent the pressure in the cavity from exceeding 1,33 times the valve pressure
rating at the specified maximum operating temperature, determined in accordance with 7.2. External cavity
relief valves shall be DN 15 (NPS ½) or larger.
If cavity relief valves are required, purchaser may specify provisions to faciliate in service testing.

B.7 Drive train strength test
B.7.1 General
The test torque shall be the greater of
a) twice the manufacturer's predicted break-away torque/thrust, or
b) twice the measured break-away torque/thrust.
The test torque shall be applied with obturator blocked for a minimum time of 1 min.
NOTE For gate valves, the thrust can be tensile or compressive, whichever is the most stringent condition.
B.7.2 Acceptance criteria
The test shall not cause any permanent visible deformation of the drive train.
For ball and plug valves, the total torsional deflection of the extended drive train when delivering the design
torque shall not exceed the overlap contact angle between the seat and obturator.
B.8 Cavity relief testing
B.8.1 Frequency
Each valve shall be tested.
Cavity relief testing is not required if protection of the cavity against over-pressure is ensured, for both the
open and the closed position, by a hole in the obturator or around the seat seal.
B.8.2 Trunnion-mounted ball valves and through-conduit gate valves with internal-relieving
seats
The procedure for cavity-relief testing of trunnion-mounted ball valves and through-conduit gate valves with
internal-relieving seats shall be as follows.
a) Fill the valve in the half-open position with water.
b) Close the valve and allow water to overflow from the test connection at each end of the valve.
c) Apply pressure to the valve cavity until one seat relieves the cavity pressure into the valve end; record
this relief pressure.
d) For valve types with second-seat relief, continue to increase the pressure to the cavity until the second
seat relieves; record the relief pressure of the second seat.
Failure to relieve at a pressure less than 1,33 times the valve pressure rating shall be cause for rejection.
B.8.3 Floating-ball valves
The procedure for cavity-relief testing of floating-ball valves shall be as follows.
a) With the valve half-open, pressurize the valve to 1,33 times the valve pressure rating specified in 7.2 for
the material at 38 °C (100 °F).
b) Close the valve and vent each end to atmospheric pressure.
c) Open the valve to the half-open position and monitor for the release of test medium trapped in the cavity.
Evidence of trapped pressurizing medium in the cavity shall be cause for rejection.

B.10 Double-block-and-bleed (DBB) valves
With the valve half-open, the valve and its cavity shall be completely filled with test fluid. The valve shall then
be closed and the valve body vent valve opened to allow excess test fluid to overflow from the valve-cavity
test connection. The test pressure shall be applied simultaneously from both valve ends.
Seat tightness shall be monitored via overflow through the valve cavity connection.
B.11 Double isolation and bleed DIB-1 (both seats bi-directional)
Each seat shall be tested in both directions.
Cavity-relief valves shall be removed if fitted. The valve and cavity shall be filled with test fluid, with the valve
half-open, until the test fluid overflows through the cavity relief connection.
To test for seat leakage in the direction of the cavity, the valve shall be closed. The test pressure shall be
applied successively to each valve end to test each seat separately from the upstream side. Leakage shall be
monitored via the valve cavity pressure relief connection.
Thereafter, each seat shall be tested as a downstream seat. Both ends of the valve shall be drained and the
valve cavity filled with test fluid. Pressure shall then be applied whilst monitoring leakage through each seat at
both ends of the valve. Some valve designs can require the balancing of the upstream and valve cavity
pressure during the downstream seat test.
B.12 Double isolation and bleed DIB-2 (one seat uni-directional and one seat bidirectional)
The bi-directional seat shall be tested in both directions.
Cavity-relief valves shall be removed if fitted. The valve and cavity shall be filled with test fluid, with the valve
half-open, until the test fluid overflows through the cavity relief connection.
To test for seat leakage in the direction of the cavity, the valve shall be closed. The test pressure shall be
applied successively to each valve end to test each seat separately from the upstream side. Leakage shall be
monitored via the valve cavity pressure relief connection.
To test the bi-directional seat from the cavity test, pressure shall be applied simultaneously to the valve cavity
and upstream end. Monitor leakage at the downstream end of the valve.

Annex D
(informative)
Purchasing guidelines
D.1 General
This annex provides guidelines to assist the purchaser with valve type selection and specification of specific
requirements when ordering valves.
D.2 Field testing
Pressures during the testing of installed valves should not exceed the pressure rating of the valve by more
than 50 % when testing with the valve partially open or by more than 10 % when testing against a closed
valve.
Tests specified with the valve half-open may also be performed with the valve fully open, provided the body
cavity is simultaneously filled and pressurized through a cavity connection.
NOTE The maximum test pressure for valves fitted with an external pressure relief can be lower (see 7.8).
D.3 Pressure relief
Certain valve designs trap pressure in the valve body cavity when the valve is in the fully open and/or closed
position. High internal pressures can result from the thermal expansion of the fluid trapped in these confined
areas.
If the valve has no self-relieving design provision, pressure-relief fittings shall be fitted in the valve body in
accordance with 7.8.
D.4 Pigging
The purchaser should examine the valve design for piggability when ordering valves for use in pipelines
requiring pigging.
NOTE 1 Venturi or reduced-bore valves are not suitable for most pigging operations, including intelligent pigging, but
can allow the passage of foam pigs.
NOTE 2 A valve in which the drive member or the obturator obstructs the bore in the otherwise fully open position (e.g.
a dual-plate check valve) is not piggable.
NOTE 3 Certain full-opening valves with pockets can allow bypass of fluid around a short pig or sphere.
D.5 Fire type-testing
The fire-resistance design of valves shall be qualified by fire type-testing in accordance with ISO 10497.
Fire resistance designs already qualified to ISO 10497, API 6FA, API 6FC, API 6FD or API 607 are also
acceptable.

Annex F
(Informative)
API Monogram
F.1 Scope
The API Monogram Program allows an API Licensee to apply the API Monogram to products. The API Monogram
Program delivers significant value to the international oil and gas industry by linking the verification of an
organization's quality management system with the demonstrated ability to meet specific product specification
requirements. The use of the Monogram on products constitutes a representation and warranty by the Licensee to
purchasers of the products that, on the date indicated, the products were produced in accordance with a verified
quality management system and in accordance with an API product specification.
When used in conjunction with the requirements of the API License Agreement, API Specification Q1, in its entirety,
defines the requirements for those organizations who wish to voluntarily obtain an API License to provide API
monogrammed products in accordance with an API product specification.
API Monogram Program Licenses are issued only after an on-site audit has verified that the Licensee conforms to
the requirements described in API Specification Q1 in total, and the requirements of an API product specification.
Customers/Users are requested to report to API all problems with API monogrammed products. The effectiveness
of the API Monogram Program can be strengthened by Customers/Users reporting problems encountered with API
monogrammed products. A nonconformance may be reported using the API Nonconformance Reporting System
available at https://ncr.api.org. API solicits information on new product that is found to be nonconforming with API
specified requirements, as well as field failures (or malfunctions), which are judged to be caused by either
specification deficiencies or nonconformities with API specified requirements.
This Annex sets forth the API Monogram Program requirements necessary for a supplier to consistently produce
products in accordance with API specified requirements For information on becoming an API Monogram Licensee,
please contact API, Certification Programs, 1220 L Street, N. W., Washington, DC 20005 or call 202-962-4791 or
by email at certification@api.org.
F.2 References
In addition to the referenced standards listed in Section 3, this Annex references the following standard:
API Specification Q1
For licensees under the Monogram Program, where cited these requirements are mandatory. Referenced
standards used by the Manufacturer may be either the applicable revision shown in Section 3 and herein, or the
latest revision.
F.3 API Monogram Program: Licensee Responsibilities
F.3.1 For all organizations desiring to acquire and maintain a license to use the API Monogram, conformance
with the following shall be required at all times:
a. The quality management system requirements of API Specification Q1,
b. The API Monogram Program requirements of API Specification Q1, Annex A,
c. The requirements contained in the API product specification(s) for which the organization desires to be
licensed,
d. The requirements contained in the API Monogram Program License Agreement.
F.3.2 When an API Licensed organization is providing an API monogrammed product, conformance with API
specified requirements, described in API Specification Q1, including Annex A, is required.
F.3.3 Each Licensee shall control the application of the API Monogram in accordance with the following:

a. Each Licensee shall develop and maintain an API Monogram Marking Procedure that documents the marking /
monogramming requirements specified by the API product specification to be used for application of the API
Monogram by the Licensee. The marking procedure shall define the location(s) where the Licensee shall apply
the API Monogram and require that the Licensee's license number and date of manufacture be marked on
monogrammed products in conjunction with the API Monogram. At a minimum, the date of manufacture shall
be two digits representing the month and two digits representing the year (e.g., 05-07 for May 2007) unless
otherwise stipulated in the applicable API product specification. Where there are no API product specification
marking requirements, the Licensee shall define the location(s) where this information is applied.
b. The API Monogram may be applied at any time appropriate during the production process but shall be removed
in accordance with the Licensee’s API Monogram Marking Procedure if the product is subsequently found to be
nonconforming with API specified requirements. Products that do not conform to API specified requirements
shall not bear the API Monogram.
c. Only an API Licensee may apply the API Monogram and its license to API monogrammable products. For
certain manufacturing processes or types of products, alternative Monogram marking procedures may be
acceptable. The current API requirements for Monogram Marking are detailed in the API Policy Document,
Monogram Marking Requirements, available on the API Monogram Program website at
http://www.api.org/certifications/monogram/.
d. The API Monogram shall be applied at the licensed facility.
e. The authority responsible for applying and removing the API Monogram shall be defined in the Licensee’s API
Monogram Marking Procedure.
F.3.4 Records required by API product specifications shall be retained for the period of time specified therein.
Records specified to demonstrate achievement of the effective operation of the quality system shall be maintained
for a minimum of 5 years.
F.3.5 Any proposed change to the Licensee’s quality program to a degree requiring changes to the quality
manual shall be submitted to API for acceptance prior to incorporation into the Licensee's quality program.
F.3.6 Licensee shall not use the API Monogram on letterheads or in any advertising (including companysponsored
web sites) without an express statement of fact describing the scope of Licensee’s authorization (license
number).
F.4 Marking Requirements
These marking requirements apply only to those API licensees wishing to mark their products with the API
Monogram.
F.4.1 Manufacturers shall either mark equipment on the nameplate with “API 6D” alone or “API 6D” in addition to
the marking requirements of Item 16 in Table 12 of Section 13.
F.4.2 As a minimum, equipment should be marked with English (Imperial) Units.
F.4.3 The API Monogram shall be marked on the nameplate, in addition to the marking requirements of Section
13. For valves smaller than DN 50 (NPS 2), the nameplate shall not be omitted, but may be attached to the valve
with stainless steel wire.
F.4.4 The API Monogram License number shall not be used unless it is marked in conjunction with the API
Monogram.
F.5 API Monogram Program: API Responsibilities
F.5.1 The API shall maintain records of reported problems encountered with API monogrammed products.
Documented cases of nonconformity with API specified requirements may be reason for an audit of the Licensee
involved, (also known as Audit for “cause”).
F.5.2 Documented cases of specification deficiencies shall be reported, without reference to Licensees, Customers
or Users, to API Subcommittee 18 (Quality) and to the applicable API Standards Subcommittee for corrective actions.

API Specification 6D / ISO 14313
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14313 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems.
This second edition cancels and replaces the first edition (ISO 14313:1999), which has been technically revised, principally by the following.
Clause 2, on the requirements for conformity to this International Standard, has been added for clarification.
Clause 7, on the requirements for allowable stresses and allowable deflection on design, has been revised and clarified.
Clause 8, on material, has been revised to align the requirements with global industry practice for carbon content and carbon equivalent for pressure-containing, pressure-controlling, welding ends and parts requiring welding.
New requirements on repairs and NDE of welding repairs have been added to Clause 9 on Welding.
A new table (Table D.2) has been added to Annex D (informative) to provide more guidance for those requirements listed in the text as requiring agreement between the manufacturer/purchaser.

API Specification 6D / ISO 14313
Introduction
This International Standard is the result of harmonizing the requirements of ISO 14313:1999 and
API Spec 6D-2002[5].
The revision of ISO 14313 is developed based on input from both ISO/TC67/SC2 WG2 and API 6D TG technical experts. The technical revisions have been made In order to accommodate the needs of industry and to move this International Standard to a higher level of service to the petroleum and natural gas industry.
Users of this International Standard should be aware that further or differing requirements can be needed for individual applications. This International Standard is not intended to inhibit a manufacturer from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative
is offered, the manufacturer should identify any variations from this International Standard and provide details.

7 设计
7.1 设计标准和计算
承压部件, 包括螺栓应用条款8中规定的材料设计。
承压部件的设计和计算应符合国际认可的设计规范或管道载荷、操作压力等标准。标准的选用应由协商决定。
注 1 国际认可的设计规范或标准，其例为ASME第VIII 卷第1册或ASME B16.34 、EN 12516-1 、EN 13445-3第2册。

API Specification 6D / ISO 14313
许用应力值应与所选设计规范或标准一致。
如果所选设计规范或标准规定试验压力小于设计压力的1.5倍，则计算出的阀体设计压力应增加，例如可应用11.3中的水压试验压力。
注 2 某些设计规范或标准在制造和试验要（包括无损检测）时需要一致性和具体应用的要求。
7.2 压力和温度额定值
公称压力等级(PN)或ASME 额定等级是用语所要求压力等级的标准。
包括在本国际标准中的阀门应按下列等级之一提供:
PN 20 (150磅级);
PN 50 ( 300磅级);
PN 64 (400磅级);
PN 100 (600磅级);
PN 150 (900磅级);
PN 250 (1500磅级);
PN 420 (2500磅级).
压力等级应按照ASME B16.34的材料组别的适用额定值表来规定。
公称压力值应按照EN 1092-1的材料组别的适用额定值表来规定。
如果压力和温度的中间值有采购方指定，则压力-温度额定值应通过线性插值法确定。
对于由不包括在ASME B16.34和 EN 1092-1中的材料制造的阀门，其压力-温度额定值应根据所应用的设计标准中材料性能来确定。
注 非金属部件能限制最大和最小压力以及最小和最大的操作温度。
在最小和最大的操作温度下的最大操作压力应标记在铭牌上。
7.3 尺寸
本国际标准中的阀门应按表1所列的公称尺寸提供。
注 在本国际标准中，首先给出的是公称尺寸（DN）其后在括号中给出的是相等NPS尺寸。
除了缩径阀门，阀门的尺寸应规定公称尺寸(DN) 或公称管道尺寸(NPS)。
带有环形孔的缩径阀门应规定连接端的公称尺寸和按照表1中的缩径孔的公称尺寸。

API Specification 6D / ISO 14313
例如1 一个DN 400至PN 20的阀门带有一个环形孔径为303 mm 的缩径阀门应规定为DN 400 (NPS 16) DN 300 (NPS 12)。
非环形孔的缩径阀门和缩径止回阀应称为缩口阀门以及由端连接的公称尺寸规定标记后面加有字母“R”的方法表示。
例如 2 带有DN 400 (NPS 16)连接端和381 mm305 mm 的矩形孔的缩口阀门应表示为400R 。
7.4 面-面和端-端结构长度
除非；另有规定，阀门的面-面和端-端(B 和 C)结构长度应按表2至表6的规定，见图1至图13中A、B 和 C结构长度。
对于未在表2至表6中规定的阀门面-面和端-端结构长度应按ASME B16.10的规定。对于未在表2至表6中或ASME B16.10规定的由协商决定。
一端为焊接端，另一端为法兰端的阀门的结构长度应为法兰连接端阀门长度的一半加上焊接端阀门长度的一半之和。
面-面和端-端结构长度的公差，对于阀门尺寸小于等于DN 250 (NPS 10)的应为±2 mm，对于大于等于DN 300 (NPS 12) 的应为±3 mm 。
如果公称尺寸和面-面或端-端的结构长度未规定在或不符合表2至表6，则应在铭牌上标明。

附录 D
(参考性的)
采购指南
D.1 总则
本附录提供的指南有助于采购方在订购阀门时对阀门类型的选择和规定技术条件要求的确定。
D.2 现场试验
已安装阀门试验时的压力，当阀门部分开启时压力不的超过阀门额定值的50%，或阀门关闭时压力不的超过阀门压力额定值的10%。
半开阀门的规定试验也可用全不开启的阀门进行操作，假设阀门腔被立即填满切通过阀腔的连接进行加压。
注： 带有外部泄压阀门的最大试验压力可以稍低（见7.8）。
D.3 泄压
当阀门处于全开和/或全关闭的位置时，特定的阀门设计将会在阀门腔体内产生腔体内压力。在特定区域腔体内流体的热膨胀回产生高的压力。
如果阀门无自泄压结构，应半7.8节在阀体上装上泄压接头。。
D.4 清管
在订购使用在管线上有清管要求的阀门时，采购方宜检查与清管工作相容的阀门结构。
注 1 文杜里或缩颈阀门可以不适用于大多数清管操作，包括智能型清管，但允许适用于泡沫清管的通道。
注 2 阀门中有驱动链或启闭件阻碍通孔，以其他方式处于全开位置的（如：双板式止回阀）不能进行清管。
注 3 特定带有凹槽的全径阀门可允许流体沿清管器或球体周围的旁通。
D.5 耐火试验
阀门的耐火设计应按照ISO 10497的耐火试验类型来评定。
以按ISO 10497、 API 6FA、 API 6FC、 API 6FD 或 API 607进行的耐火设计也可以接受。

API 会徽
F.1 适用范围
API会徽允许API 持证者在产品上使用API会徽。产品上标有API会徽提供了显著的证据，即：这些产品符合确认的质量体系，符合API承认的国际油气工业产品规范。API会徽大纲向国际油气工业递交了重要的数据，通过将供方的质量体系的确认和满足规定的产品规范要求联系在一起。
当连同使用API取证协议要求时，API Q1规范全部规定了希望按API产品规范承提供的有API字母的产品的供货方自愿取证的要求。
只有在通过现场审核确认取证者符合API Q1规范全部描述要求以及API规范产品的要求，API会徽大纲证书才能发放。用户/使用者被要求报告有API字母的产品的所有问题。API会徽大纲的有效性能通过用户/使用者报告发生在有API字母的产品上的问题得到增强。不一致报告可使用https://ncr.api.org.中的API不一致报告体系。API征求API 中规定的不一致品要求的新产品上的信息、 失效因素（失效的故障），其可以判断规范缺陷或API 规定的不一致品要求所引起的因素。
对API会徽取证者的指导性文件，本附录按照API规定的要求阐明了API会徽大纲要求，请与API联系，地址1220 L Street, N. W., Washington, DC 20005或电话02-962-4791或电子邮箱certification@api.org。
F.2 引用标准
除了第三章所列的参考标准值以外，本附录参考如下标准：
API Q1规范
对于会徽大纲的持证者，引用这些要求是强制性的，由制造厂使用的参考标准既可以是第三章所列的版次，也可以是最新版本所列的版次。
F.3 API 会徽大纲: 持证者的责任
F.3.1 对于所有想要获得保持和使用会徽的组织机构，随时要求与下列内容相符合：
a. API Q1规范质量管理体系要求，
b. API Q1规范，附录A，API会徽大纲要求，
c. 对于取证组织机构，API 规范产品中包含的要求，
d. API大纲会徽协议中包含的要求。
F.3.2 当持证机构提供API会徽产品，需要其符合API 规定要求，API Q1规范，包括附录A。
F.3.3 每个持证者应按下列要求控制API会徽的使用：

API Specification 6D / ISO 14313
a. 持证者按照适用的API产品规范规定的标志程序，在 产品上使用证书号、制造日期。至少，制造日期应为代表月分的两位数，以及代表年份的两位数（如2007年的05-07）除非在API产品规范上规定。当无API产品规范标记要求时，持证者应限定规范产品的使用地方。
b. 在制造过程中，API会徽和在任何前党时间使用，当应按持证者的API会徽标记进行移出，如果随后发现产品与API规定的要求不一致。与API规定要求不一致的产品不应显示API会徽，
c. 只有API 持证者可以应用会徽和其证书用于有API字母的产品。对于某些生产工艺或产品类型，应采用可选者的会徽标记。对于会徽标记规程的先行的API 要求也应在API 政策文件、会徽标记要求以及会徽大纲网页http://www.api.org/certifications/monogram/中详细列出。
d. API会徽应在持证者的工厂使用，
e. 使用和去除API会徽应在持证者API会徽标记规程中明确定义。
F.3.4 API 产品规范要求的记录应按规定的周期予以保存。规定的质量体系有效运行的演示业绩的记录应至少保存5年。
F.3.5 对于预期的证书持有者的质量大纲的改变，对于质量手册的程度要求的改变，早与证书持有者的质量体系合并之前应提交给API 。
F.3.6 在没有证书授权（证书编号）的申明情况下，证书持有者不应在信头或任何广告中（包括公司-赞助的网址）使用API会徽。
F.4 标记要求
这些标记要求仅适用于那些希望在他们的产品上标有API 会徽的API 持证者。
F.4.1 制造厂除13章中表12的第16项的标记要求之外，还应在带有“API 6D”设备的铭牌上有标记。
F.4.2 作为最低要求，设备上的标记应采用英制（权威的）单位。
F.4.3 除了第13章的标记要求之外，还应在铭牌上标上The API 会徽标记。对于小于DN 50 (NPS 2)的阀门，铭牌上不应省略，而是用不锈钢线附在上面。
F.4.4 不应使用API 会徽证书编号除非标记在连接件。
F.5 API 会徽大纲: API 责任
F.5.1 API 应保持报告发生在有API字母的产品上的问题。API 规定的不一致品案例要求可为审核持证这的因素（也被称为审核“原因”）。
F.5.2在没有引用取证者、顾客或使用者的情况下，应报告规程缺陷记录的案例，以便从API 小组委员会18和适当的API 标准小组委员会获得纠正的措施。
