Heat treatment
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 treated provided they are cooled in still air.
Application:
Low and middle pressure fluid pipeline, boiler, petroleum and natural gas industry, drilling, chemical industry, Refinery Company, fertilizer industry, power station, shipbuilding, onshore platform.
Standard Marking:
Each fitting shall be permanently marked to show the following:
(a) manufacturer’s name or trademark
(b) material identification, either the ASTM or ASME grade designation 2
(c) schedule number 1 or nominal wall thickness in mm
(d) size — the nominal pipe size (NPS) identification number related to the end connections shall be used
(e) compliance — see para. 4.4 for standard and spe-cial fitting marking A manufacturer may supplement these mandatory markings with others, including a DN size designation, but confusion with the required marking shall be avoided.
Materials:
The material in standard A234 for fittings shall consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added and shall conform to the chemical requirements of Table 1. Unless otherwise speci-fied for carbon steel plates, the steel may be made to either coarse grain or fine grain practice. Grade WP9 shall be made to fine grain practice
