BW 90 degree elbow is a commonly used pipe fitting in many insductries.ASTM A234 WPB / WPC are both represent butt welded (BW) fittings in American Standard.WPB and WPC are different grade of butt welded fittings,among this,WPB is more chosen grade.

 

BW 90 degree ELBOW

BW 90 degree elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

 

There are two types of butt welded elbow:Long Radius(LR) and Short Radius(SR).

 

Long Radius Elbow

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D.

 

Short Radius Elbow

Short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e R = 1.0D.
