ASTM A234Gr.WPB TEE 2SCH40 SMLS ASME B16.9
ASTM A234 WPB Sch 40 Fittings covers carbon steel fittings of welded and seamless construction secured by the most recent amendment of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97.
Fittings made from forgings may have 0.35 max carbon and 0.35 max silicon with no minimum.CS ASTM A234 Seamless Butt Weld Fittings: 1/2″ – 10″
CS ASTM A234 gr WPB Welded Butt Weld Fittings: 1/2″ – 48″ Mostly these specified ASTM A234 WPB Pipe Fittings include steel 45 degree elbow bend, 90 degree elbow bend , tees, concentric reducers or eccentric reducer, crosses, caps, flanges, nipples, gaskets, studs etc. If required, buyers also have the option of choosing a surface finished Bw A234 WPB Fittings, depending on the requirement.The sum of Cu, Ni, Cr, and Mo shall not exceed 1.00%.
The sum of Cr and Mo shall not exceed 0.32%.
For each reduction of 0.01% below the specified C max, an increase of 0.06% Mn above the specified max will be permitted, up to a max of 1.35%.
The max carbon equivalent (C.E.) shall be 0.50, based on heat analysis and the formula C.E.=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
