The A234 standard includes carbon steel and alloy steel grades such as WPB, WP5, WP9, WP11, WP12, WP22, and WP91.
C-Mn-Si is low carbon alloy steel. It is similar to domestic Q345, Q345R, etc., and is equivalent to domestic Fe-1-2 material. Welding materials of E50 series for welding Fe-1-2 group.
There are many grades (grades) in ASTM A234 elbows, such as: WPB, WPC, WP11, WP12, WP22, WP91, etc.
A234 elbows usually come in two types: long radius (usually 1.5 times the pipe diameter) and short radius (usually 1 times the pipe diameter).
ASME B16.9 carbon steel elbows usually use butt-weld connections, which means that the elbow and pipe are connected by welding, providing high strength and sealing.
