The WPB is not short hand for any process. It is simply an identifier developed by ASTM. The fittings in question are manufactured in the same manner as the companion pipe for this specification. In very large sizes, the fittings may be manufactured in pieces and welded together as is the case for many large fittings. Note the reference below. ASTM A standard covers steel fittings of seamless and welded types. In these standard Grade WPB is the most common material used for medium and high temperature pipelines.
W means weldable, P means pressure, B is grade b, refer to the minimum yield strength. B and C. Process Killed steel, with forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added. Forging or shaping operations performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations.
A WP11 elbow Heat Treatment After forming at an elevated temperature, fittings are cooled to a 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 temperatures specified are metal part temperatures. The regular fittings of A WPB pipe fittings are elbows, tees, reducers, caps, cross.
ASTM A234 Carbon and Alloy Steel Pipe Fittings
What is Steel pipe fittings Steel pipe fitting are made of carbon or alloy steel pipe, plates, profiles, to a certain shape that could make a function Change the fluids direction or rate in pipeline systems. Mostly these fittings includes steel elbow 45 or 90 degree bend , tee, reducer concentric or eccentric reducer , cross, caps, nipple, flanges, gasket, studs and etc. For industrial purposes, in pipeline systems usually we need to change the transmission direction; Adjust fluids oil and gas, water, slurry flow rate; Open or close the pipelines, etc. So to complete these activities, steel pipe fittings will be applied. It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications.
