  ASTM A234 WPB Fittings   are constructed from several material grades. The standard is for high or moderate-temperature pressure pipes and fittings. ASTM A234 covers seamless and welded forged carbon steel and alloy steel fittings covered by the most recent edition of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are designed for use in pressure pipe and pressure vessel fabrication at moderate and high temperatures. Western Steel Agency is a leading   ASME SA 234 Gr WPB Pipe Fittings Manufacturer and Supplier in India. According to the ASME/ANSI B16.9 and B16.28 standards, the  ASME SA 234 Gr WPB Pipe Elbow  and other fittings can come in a variety of sizes.

The internal weld of the flange to the pipe is recessed by at least the thickness of the wall plus 3 millimeters (3/16”) of an inch. This is to keep the gasket's face and seating area safe. Although a Slip On Flange is initially less expensive than a Weld Neck Flange , there are two welds on the rear side and one on the inside of the flange, as well as the additional inspection of the second weld, tripling the weld and inspection costs. Because fittings are designed for butt weld connections, the Slip-On Flange is meant to be welded to the pipe before being fitted. The Weld Neck Flanges base gradually tapers away from the bolted connection to the pipe, making it instantly recognizable. The Point of Weld on the Weld Neck is supplied with a specific bore to match the connecting pipe or fitting. A full penetration butt weld is used to make t...
