API Spec 11IW-2000 pdf free download.Specification for Independent Wellhead Equipment.
1 Scope 1.1 PURPOSE This specification was formulated to provide for the avail- ability of safe, dimensionally and functionally interchangeable independent wellhead equipment. The technical content pro- vides requirements for performance, design, materials, testing, inspection, welding, marking, handling, storing and shipping. 1.2 APPLICATIONS 1.2.1 Coverage This specification covers the independent wellhead equip- ment utilized for pressure control systems for the production of oil and gas. Specific equipment covered by this specifica- tion is listed as follows: a. Independent wellheads. b. Top connectors. c. Tubing and casing slip hangers. d. Tubing and cashing mandrel hangers. e. Packoffs. f. Belled nipples. g. Connector flanges. h. Stripper adapters. The typical equipment nomenclature used in this specifica- tion is shown in Figures 1, 2, 3, and 4. 1.2.2 Service Conditions 1.2.2.1 General Service conditions refer to classifications for pressure, temperature, and the various well-bore fluid and operating conditions. 1.2.2.2 Pressure Ratings Pressure ratings indicate rated working pressures expressed as gage pressure (psig). 1.2.2.3 Temperature Rating Temperature rating indicates the temperature range, from minimum ambient to maximum flowing fluid temperature, expressed in degrees Fahrenheit (degrees F). 1.2.2.4 Materials Class Rating Materials class rating indicates the material of the equip- ment components.
2 Referenced Publications 2.1 GENERAL This specification includes by reference, either in total or in part, the latest edition of other API, industry and government standards listed in 2.5. 2.2 REQUIREMENTS Requirements of other standards included by reference in this specification are essential to the safety and interchange- ability of the equipment produced. 2.3 EQUIVALENT STANDARDS Standards referenced in this specification may be replaced by other international or national standards that can be shown to meet or exceed the requirements of the referenced stan- dards. Manufacturers who use other standards in lieu of stan- dards referenced herein are responsible for documenting the equivalency of the standards. 2.4 APPENDICES Appendices to this specification shall not be considered as requirements. They are included only as guidelines or information. 2.5 DOCUMENTS API Spec 5B Specification for Threading, Gauging, and Thread Inspection of Casing, Tubing, and Line Pipe Threads Spec 6A Specification for Wellhead and Christmas Tree Equipment ASME/ANSI 1 B16.5 Pipe Flanges and Flanged Fittings ASME Boiler and Pressure Vessel Code, Section VIII: Rules for Construction of Pressure Vessels ASME Boiler and Pressure Vessel Code, Section IX: Qualification Standard for Welding and Brazing Procedures, Welders, Brazers, and Welding and Brazing Operators
3.6 carbon steel: An alloy of carbon and iron containing a maximum of 2% carbon, 1.80% manganese, and residual quantities of other elements, except those intentionally added in specific quantities for de-oxidation (usually silicon and/or aluminum). 3.7 casting: (1) An object at or near finished shape obtained by solidification of a substance in a mold. (2) Pour- ing molten metal into a mold to produce an object of desired shape. 3.8 connections, end and outlet: Integral threads, male or female; and flanges, through-bolted; or any other means used to join together equipment that contains or con- trols pressure. 3.9 connector flange: An ASME/ANSI B16.5 flange which may be an end connection on a Flanged Independent Wellhead or an Adapter Flange such as blind, threaded, drill- ing or slip type. 3.10 ductile iron: A cast iron that has been treated while molten with a magnesium or cerium-containing master alloy to transform primary graphite into spheroidal form during solidi- fication. Also known as nodular iron or nodular cast iron. 3.11 dynamic seal: Seals in which motion exists relative to the sealing surface after installation. 3.12 flanged independent wellhead: Any casing or tubing head or spool covered by this specification which has as the upper end connection a flanged connection as defined in 10.1. 3.13 forging: (1) Plastically deforming metal, usually hot, into desired shapes with compressive force, with or without dies. (2) A shaped metal part formed by the forging method. 3.14 heat (cast lot): Material originating from a final melt. For remelted alloys, a heat shall be defined as the raw material originating from a single remelted ingot.
