PURPOSE. This specification was formulated to provide for safe and functionally interchangeable surface and subsea choke and kill systems equipment utilized for drilling oil and gas wells. Other parts of the Choke and Kill System not specifically addressed in this document shall be in accordance with the applicable sections of this specification.

Technical content provides the minimum requirements for performance, design, materials, welding, testing, inspection, storing and shipping.

APPLICATIONS

EQUIPMENT. Equipment, specific to and covered by this specification, is listed below:

Actuated valve control lines

Articulated Choke & Kill Line

Drilling choke actuators

Drilling choke control lines, exclusive of BOP control lines and subsurface safety valve control lines

Drilling choke controls

Drilling chokes

Flexible choke and kill lines

Union connections

Rigid choke and kill lines

Swivel unions

OTHER EQUIPMENT. Other Equipment included in specification, but covered by other API Specifications is listed below:

Check valves

Chokes

Crosses and tees

Flanged, studded end and outlet connections

Flow through valves

Hubbed end and outlet connections

Production choke actuators

Ring gaskets

Studs and nuts

Threaded end connections

Valve actuators

SERVICE CONDITIONS. Service conditions refer to requirements for pressure, temperature and fluid compatibility as delineated in Section 3, Design Requirements.

Because Choke and Kill Systems are mobile and are moved to different areas, all service conditions they may be exposed to cannot be defined in this document. However, conditions that are consistent with API Specifications 6A and 16A have been adopted, which define a sour, moderately corrosive environment. If severe corrosion, abrasion, temperatures or high levels of sour gas are expected, the user and manufacturer shall jointly address the requirements and determine the suitable product for the application.

PRODUCT SPECIFICATION

1. This specification establishes minimum requirements for products listed in Section 1.2.1, Equipment.

2. Products listed in Section 1.2.2, Other Equipment, that have requirements established in API Specification 6A, 16th edition shall have a minimum of product specification level PSL 3, material class EE and a Temperature Rating from Section 3.5.2 as appropriate for Choke and Kill System applications.

3. Choke and Kill System equipment manufactured prior to the effective date of this specification is outside the scope of this document.

DIMENSIONAL UNITS. For the purpose of this specification the decimal inch system is the standard for dimensions. Nominal sizes will continue to be shown in fractions. The Appendix, Section 3 gives fraction to decimal equivalence. For the purposes of this specification, the fractions and the decimal equivalents are equal and interchangeable.

METRIC/SI CONVERSION. Metric system or International System of Units conversions are listed in Section 10.1, SI unit dimensions are listed in parentheses alongside the decimal inch units throughout the document.

APPENDICES. Section 10 shall not be considered as requirements. The Appendices are included as guidelines or information.
