A pipe Butt Weld Elbow is actually a fitting that is being installed in between the two lengths of tube or a pipe to allow in changing the direction of a flow. The change in the direction is done generally in the 45°or 90°route.A860 WPHY60 represents American standard pipeline steel butt welded pipe fittings.

 

45 degree elbow VS 90 degree elbow

  • The function of a 45 Degree Long Radius Elbow is same as 90 degrees long and short elbow, but the measurement and dimensions are different to that of a 90 degree long and the short elbow.
  • The radius of both the 45 degree and 90 Degree long and short elbow is the same however, the center to face dimension is not equivalent due to the smaller degree of bend.
  • Compared with 90 degree elbow, 45 degree elbow produces less friction and lower pressure.

 

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.

 

The end of Butt welded fittings are connected to the pipe system by butt welding.Butt weld fittings provide permanent leak-proof performance.BW fittings could made from seamless or welded pipe,and then through several processes formed to get the shape of pipe fittings.
