SPECIFICATION

6DSS

(ISO 14723)

API Specification 6D (ISO 14313) is the recognized industry standard for pipeline valves that was formulated under the jurisdiction of the API Standards Subcommittee on Valves and Wellhead Equipment (API SC6). ISO 14313 was prepared by Technical Committee ISO/TC 67: Materials, equipment and offshore structures for petroleum and natural gas industries, Subcommittee SC 2, Pipeline transportation systems.

API Specification 6DSS (ISO 14723) is based on ISO 14313. It has been devel-oped to address special requirements specific to subsea pipeline valves. This international standard is also under the jurisdiction of the API Standards Subcommittee (API SC6) on Valves and Wellhead Equipment. ISO 14723 was prepared by Technical Committee ISO/TC 67: Materials, equipment and offshore structures for petroleum and natural gas industries, Subcommittee SC 2, Pipeline transportation systems.

Both these standards specify requirements and provide recommendations for the design, manufacturing, testing and documentation of ball, check, plug and gate valves for applications in pipeline systems meeting the requirements of ISO 13623 for the petroleum and natural gas industries. API Specification 6D (ISO 14313) is also specified as the base standard for manufacture of subsea equipment in accordance with API Specification 6DSS (ISO 14723). These inter-national standards are not applicable to valves for pressure ratings exceeding Class 2500 (PN 420).

These standards do not prescribe requirements for field use, testing or repair of covered products nor covers aftermarket remanufacture and repair activities. These requirements are covered under API 6DR recommended practice. Major sections of API 6D (ISO 14313) and API 6DSS are:

• Scope • Normative References • Terms and Definitions • Valve Types and Configurations (ball, check, gate, plug) • Design • Materials • Welding

EQUIPMENT

API Specification 6D (ISO 14313) and API 6DSS (ISO 14723)

cover Pipeline and Subsea Pipeline Valves as follows:

• Quality Control • Testing • Marking • Storage/Shipping • Documentation • Annex’s (NDE/testing/documentation/purchasing)

Background

Normative references are taken from:

• ANSI – American National Standards Institute • ASME – American Society of Mechanical Engineers • ASNT – American Standard for Nondestructive Testing • ASTM – American Society for Testing and Materials • AWS – American Welding Society • EN – Euro Norm • ISO – International Standards Organization • MSS – Manufacturers’ Standardization Society • NACE – National Association of Corrosion Engineers

The minimum Product Specification Level (PSL) for an SSV or USV is PSL 2.

Special Design Requirements

Requirements for design apart from general requirement for valves include: • Acceptable design codes and calculations for pressure containing parts/

materials as specified in B16.34 and other international design code. • Pressure-containing design and calculations in accordance with agreed,

internationally recognized design codes or standards, for example ASME Section VIII Division 1 or Division 2, or ASME B16.34.

• The minimum design thrust or torque for design calculations shall be at least two times the predicted breakaway maximum design thrust or torque of any operating condition at 38°C (100°F) at maximum pressure differential (MPD), or at an operational temperature and/or pressure causing the highest thrust or torque.

• Max force on hand-wheel breakaway thrust/torque 180 N. For API 6DSS valves, if required, ROV interface is per ISO 13628-8 (API 17D).

• Visible position indicator showing the open and closed position of the obturator (closure member) of the ball, disc, gate or plug.

TEMPERATURE

CLASSES

PRESSURE

RATINGS

TEMPERATURE

CLASSES

Valves covered by these international standards are furnished per ANSI/ASME rating or the nominal pressure (PN) classes in seven different pressure ratings representing the maximum working pressure of the equipment as follows:

Class 150 (PN 20) @ Class 900 (PN 150) @

Class 300 (PN 50) @ Class 1500 (PN 250) @

Class 400 (PN 64) @ Class 2500 (PN 420) @

Class 600 (PN 100) @

Pressure-temperature ratings for ANSI/ASME class-rated valves are in accor-dance with the applicable rating table for the appropriate material group in ASME B16.34 and for PN rated valves per EN 1092-1.

For intermediate design pressures and temperatures, the pressure-temperature rating is determined by linear interpolation.

Pressure-temperature ratings for non-ASME B16.34 and non-EN 1092-1are determined from the material properties in accordance with the applicable design standard.

For 6DSS valves, the minimum design temperature is 32°F (0°C) unless otherwise specified.

If the maximum pressure differential (MPD) at which the valve is required to be opened is not specified, then the pressure rating as determined for material at 100°F (38°C) shall be the MPD.

Note: Non-metallic parts can limit maximum pressures and minimum and maximum temperatures.

MATERIAL

CLASSES

DESIGN

VERIFICATION

TESTING

Performance verification testing is performed on production valves to vali-date that the performance requirements specified for pressure, temperature, mechanical cycles and standard test fluids are met in the design of the product.

Performance Verification Testing may include: • Hydrostatic Shell/Seat Testing

• Pneumatic/Air/Gas Testing • Pressure/Temperature Cycles • Load/Mechanical Cycles

• Functional and Operational Testing

Although pneumatic/air/gas testing is an optional requirement in API Specification 6D (ISO 14313), Cameron is proud to offer a wide variety of products proven to meet, and often exceed, the performance verification requirements of API 6D (ISO 14313).

There are various Material Classes which specify minimum material

requirements for general or sour service. API 6D (ISO 14313) and/or 6DSS (ISO 14723) equipment must be designed, tested and marked as satisfactory for one of these Material Classes.

• Austenitic stainless steel weld end valves: - 0.03% max. carbon

- 0.08% max. carbon if the material is stabilized

• Fracture toughness on base material and weld metal is based on yield strength (SMYS) and not tensile strength for all carbon/alloy material design temperature as:

Minimum Material Requirements

• Manufacturer shall develop documented material specification for pressure-containing and pressure-controlling parts agreed design standard such as ASME B16.34.

• Service compatibility - Non-metallic parts for valves intended for hydrocarbon gas service for valves above class 600 shall be resistant to explosive decompression.

• Chemical/carbon equivalent restrictions - carbon steel weld end valves:

MATERIAL

CLASSES

(continued)

• Bolting material with a hardness exceeding HRC 34 (Rockwell C) or HBW 340 (Brinell) are not to be used for valve applications where hydrogen embrittlement can occur, unless otherwise agreed.

• Sour service - HIC testing is mandatory on plate material per NACE TM 0284. • As defined by National Association of Corrosion Engineers (NACE)

Standard MR0175, these material classes will also include an H₂S rating in compliance with NACE Standard MR0175.

SOUR SERVICE &

ISO 15156

(NACE MR0175)

Sour service is defined as any case where the absolute partial pressure of hydrogen sulfide (H2S) exceeds 0.05 psi (0,0003 Mpa). As an example, if the

total shut-in pressure is 2000 psi (13,8 Mpa), a concentration of 25 parts per million (ppm) is equivalent to 0.05 psi partial pressure, so ISO 15156 would apply. API 6D (ISO 14313) and API 6DSS (ISO 17423) specifications require that materials for pressure-containing and pressure-controlling parts including bolting used in sour service meet the requirements of ISO 15156 (all parts).

ISO 15156 lists acceptable materials, including any restrictions on mechanical properties, heat treat procedures and method of manufacture. As an example, carbon and low-alloy steels must have a hardness of no more than 22 HRC. If acceptable low alloy steel is welded in an exposed area, it must be stress relieved at a temperature of at least 1150ºF (593ºC).

(NACE MR0175

(continued)

There are sound reasons for the changes to NACE MR0175. Previous editions did not address the effects of environmental factors other than H₂S on the resistance of materials to sulfide-stress cracking. While the major oil and gas companies, drilling companies and equipment manufacturers were aware of the limitations of the materials they used, the standard did not provide enough guidance for companies with less experience or metallurgical expertise.

In a few cases, materials that have been approved in MR0175 and widely used for certain components are no longer permitted by the standard. An example is the use of 17-4 PH® _{stainless steel for tubing hangers. In other}

cases, the new restrictions may dictate a change in materials from past usage. For instance, tubing hangers or valve stems made from 410 or F6NM stainless steel are approved for use only if the partial pressure of H2S is no higher

than 1.5 psi. As a result of such limitations, it may not be possible to certify that a product complies with NACE MR0175, without knowing specific fluid conditions.

Another change to the standard is the expansion of scope to cover stress corrosion cracking (SCC) as well as sulfide-stress cracking (SSC). As a result, AISI 316 and other austenitic stainless steels are limited as to service temperature and chloride content as well as H2S.

Recognizing the impact of the new environmental limits in NACE MR0175, (ISO 15156) the standard now allows purchasers to qualify materials for use outside those limits, or to use materials not listed. This can be done by using “like for like” materials in an existing field or by documenting successful ser-vice history in a comparable application. Purchasers can also perform material qualification testing, as detailed in MR0175, and avoid the lengthy balloting and approval process.

There are many additional factors that can dramatically influence the selection of proper materials in addition to those included in NACE. Factors such as temperature are important considerations during completion and throughout the service life of the well.

THE API

MONOGRAM

PROGRAM

Program Description

The American Petroleum Institute administers the API Monogram Program as a service to the global oil and natural gas industry. The program is widely known for the API Monogram symbol, which can be found physically marked on many products used in the industry today. The mark is a warranty by the licensed product manufacturer or service provider to the API and to the purchaser of the product, that (a) the item complies in every aspect with the applicable API Product Specification in effect on the date of manufacture and (b) the item was manufactured in conformance with the manufacturer’s API-approved quality management system.

API Product Standards and the API Monogram Program

There are more than 70 API Specifications that are currently eligible for licensing under the API Monogram Program. These standards cover a wide variety of products and services used in the industry and are maintained by API’s internationally recognized standards organization to keep current with practices and technology used in the industry today.

API Quality Management System

The API Monogram Program quality management system is based on ISO 9001 with the addition of requirements that are of specific importance to the oil and natural gas industry. The quality management system is documented in API Specification Q1.

The API Licensing Process

Organizations may voluntarily apply to API for a license to produce and mark products with the official API Monogram. In the application process, the organization must identify the API standard(s) it expects to conform to under the license, which specific products/services within that standard will be included or excluded under the agreement and the physical location of the facility that will produce the product. Upon acceptance of the organization’s application, API will (a) review the organization’s quality management system documentation for compliance with API Specification Q1; (b) perform an on-site audit of the implementation of the organization’s quality management system and (c) conduct and on-site evaluation of the organization’s capability to produce products in compliance with the applicable API specification(s). If approved, the organization will be issued a numbered license granting it the right to use the API Monogram for a period of three years, during which time the organization may be subject to additional, unannounced audits by the API.

Using the API Monogram

Under the license agreement, the organization may not physically mark any product with the API Monogram that does not fully conform with the applicable API Standard and/or if the product manufacture deviated from the licensed organization’s quality management system. For each use of the API Monogram, the organization is also required to mark the unique license number issued by the API adjacent to the monogram, which is traceable to the individual API-licensed facility that produced the product.

API

SPECIFICATION Q1

(ISO 29001)

API Specification Q1 (ISO 29001) is intended to be used in conjunction with international oil and gas product standards by internationally licensed manufacturers. Used in this manner, API Specification Q1 delivers significant value to the industry by providing a cohesive link between the accreditation of a manufacturer’s quality system and their ability to provide products meeting industry and customer requirements.

API Specification Q1 differs from generic quality systems (e.g., ISO 9001) by its role in the voluntary licensing of manufacturers to provide oil and gas industry products in accordance with API specifications. API licenses are only issued after an on-site survey has confirmed that the licensee adheres to the requirements of both the quality system standard API Specification Q1 and the requirements of an international oil and gas product specification recognized by the oil and gas industry and API. In contrast, generic quality system requirements are normally intended to be applied to any industry or product through contractual agreements with or without industry standards or specifications.

API Specification Q1 includes the basic quality management system requirements of ISO 9001 and is also published as ISO 29001.
