What is A234 WP11/ WP9 Pipe Fittings?
ASTM A234/A234M-10 Standard Specification for Pipes Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service
This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP- 79, MSS-SP—83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. Fittings differing from these ASME and MSS standards shall be furnished in according with Supplementary Requirement S58 of Specification A960/A960M
A234 WP1/ WP5/ WP9/ WP11/ WP22 / WP91 Fittings Heat Treatment
Heat Treatment Procedures – fittings, after forming at an elevated temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air. Heat treatment temperature specified are metal (part) temperatures. Heat- treatment fittings shall be treated according to paragraph 7 in specification A960/A960M.
WPB, WPC, and WPR Fittings
Hot-formed WPB, WPC, and WPR fittings upon which the final forming operation is completed at a temperature above 1150 °F [620° C ] and below 1800 °F [980 °C] need not be heat treatment provided they are cooled in still air. 7.2.2 Hot-formed or forged WPB, WPC, and WPR fitting finished at temperature in excess of 1800 °F [980 °C] shall subsequently be annealed, normalised, or normalized and tempered. Hot-forged fittings NPS 4 or smaller need not be heat treated.
WPB, WPC, and WPR fittings over NPS 12, produced by locally heating a portion of the fitting stock to any temperature for forming, shall be subsequently annealed, normalized, or normalized and tempered. fittings such as elbows tees, header tees, reducers and lap joint stub ends with a carbon content less than 0.26%, NPS 12 and under, shall not require heat treatment after forming a locally heated portion of the fitting.
Fittings of Grades ASTM A234 WP1, WP11 Class 1, WP11 Class 2, WP11 Class 3, WP12 Class 1, WP12 Class 2, WP22 Class 1, WP22 Class 3, WP5, and WP9 shall be finished in the full-annealed, isothermal – annealed, or normalized and tempered condition. If normalized and tempered, the tempering temperature for WP11 Class 1, WP11 Class 2, WP11 Class3, WP12 Class 1, and WP12 Class 2 shall not be less than 1150 °F [620 °C] for Grades WP5, WP9, WP22 Class 1, and WP22 Class 3 the tempering temperature shall not be less than 1250 °F [675 °C]
