Carbon Steel A234 WPB Butt Weld 90 Degree Elbow Production Description

 

The function of butt weld elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° .
According to the material, it can be divided into carbon steel, alloy steel and stainless-steel.
According to its radius of curvature, there are long radius  and short radius Stainless Steel A403 Butt Weld 90 Degree Elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

 

Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings
