ASME B16.9 ASTM A234 WPB 90 Degress LR SMLS Elbow
What is the A234 WPB ?
ASTM A234 WPB Elbow is the standard specification for pipe fittings Elbow of wrought carbon steel and alloy steel for moderate and high-temperature service. SA234 WPB Elbow in accordance with ASME B16.9.Carbon steel pipe fittings manufactured to ASMT A234 are usually furnished in the butt-welding form in accordance with ASME B16.9 or ASME B16.49. CS Elbow A234 WPB are widely used in different industries like power, engineering, construction and many mor

Notes:
For each reduction of 0.01% below the specified C maximum, an increase of 0.06% Mn above the specified maximum will be permitted, up to a maximum of 1.35%.
The sum of Cr and Mo shall not exceed 0.32%.
The sum of Cu, Ni, Cr, and Mo shall not exceed 1.00%.
The maximum 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.

Where the wall thickness lies between two values above, the min elongation value is determined by the following equations:
Longitudinal E=48t+15.00
Transverse E=32t+10.00
E = elongation in 2in [50mm], %
t = actual thickness of specimen, in [mm]
