1.2 APPLICATIONS 1.2.1 Coverage This specifcation covers equipment utilized for pressure control systems for the production of oil and gas. Specific equipment covered by this specification is listed as follows: a. Wellhead Equipment ●Casing Head Housings ●Casing Head Spools ●Tubing Head Spools ●Crossover Spools ●Multistage Head Housings and Spools b. Connectors and Fittings ●Crossover Connectors Tubing Head Adapters ●Top Connectors ●Tees and Crosses ●Fluid Sampling Devices ●Adapter and Spacer Spools c. Casing and Tubing Hangers ●Mandrel Hangers ●Slip Hangers d. Valves and Chokes ●Single Completion Valves ●Multiple Completion Valves ● Actuated Valves ●Valves Prepared for Actuators ●Check Valves Chokes ●Surface and Underwater Safety Valves and Actuators for Offshore Service e. Loose Connectors [Flanged, Threaded, Other End Con- nectors (O.E.C.), and Welded] ●Weld Neck Connectors
1.2.2 Service Conditions a. General Service conditions refer to classifications for pressure, tem- perature, and the various well-bore constituents and operating conditions. b. Pressure Ratings Pressure ratings indicate rated working pressures expressed as gage pressure (psig or MPa gage). C. Temperature Ratings Temperature ratings indicate temperature ranges, from minimum ambient to maximum flowing fuid temperatures, expressed in degrees Fahrenheit (°F) or degrees Celsius (°C). d. Materials Class Ratings Materials class ratings indicate the material for the equip- ment components. A guideline (not a requirement) for the basic well-bore constituents and operating conditions is cov- ered in Appendix A. 1.3 PRODUCT SPECIFICATION LEVELS (PSL) a. General This specification establishes requirements for four prod- uct specification levels. These four PSL designations define different levels of technical requirements. Appendix A pro- vides guidelines (not requirements) for selecting an accept- able PSL. b. PSL 1 PSL 1 includes practices currently being implemented by a broad spectrum of the industry for service conditions recom- mended in Appendix A of this specification. c. PSL2 PSL 2 includes all the requirements of PSL 1 plus addi- tional practices currently being implemented by a broad spec- trum of the industry for service conditions recommended in Appendix A of this specification.
3.2.7 as shipped condition: The condition of the prod- uct or equipment when it is ready for shipment. 3.2.8 authorized facility: A facility authorized under the applicable quality assurance program specified by the opera- tor on the purchase order (applicable to SSV/USV equip- ment). 3.2.9 authorized quality assurance program: API or SPPE Quality Program (applicable to SSV/USV equipment). 3.2.10 back pressure valve: A check valve that is installed through the Christmas tree, into the tubing hanger, and prevents well fuids from flowing out of the well. 3.2.11 body: Any portion of API Spec 6A equipment between end connections, with or without internal parts, which contains well-bore pressure. 3.2.12 bolting: Threaded fasteners (studs, nuts, bolts and capscrews) used to assemble pressure containing parts or join end or outlet connections. 3.2.13 bonnet: A pressure- containing closure for a body, other than an API end or outlet connection. 3.2.14 bottom casing packoff: A mechanism that seals off annular pressure between the OD of a suspended tubular member or hanger and the ID of the spool or tubing head adapter being placed over the suspended tubular or hanger.
3.2.47 flange, loose: A fange, as manufactured, not intended to be made integral with another piece of API Spec 6A equipment. There are blind, threaded, spacer, welding neck, studded, or other connected adapter flanges. 3.2.48 flange, threaded: A flange having a sealing face on one side and a female thread on the other for the purpose of joining fanged connections to threaded connections. 3.2.49 flange, welding neck: A fange with a neck on the side opposite the sealing face prepared with a bevel to weld to corresponding pipe or transition pieces. 3.2.50 forging: (1) Plastically deforming metal, usually hot, into desired shapes with compressive force, with or with- out dies. (2) A shaped metal part formed by the forging method. 3.2.51 form: The essential shape of a produce including all its component parts. 3.2.52 function: The operation of a product during ser- vice. 3.2.53 gage and test port connections: Holes drilled and tapped into API Spec 6A equipment through which inter- nal pressure may be measured or through which pressure may be applied to test the sealing mechanisms.
