A234 WPB Elbow Carbon Steel

A234 WPB elbow is the most chosen carbon steel elbow in all the types of elbows.A234 WPB is carbon steel grade for butt welded fittings;BW elbows have LR (long radius)and SR (short radius).Elbows have 90deg and 48deg to change the direction of the pipe system.

A234 WPB elbow is butt welded elbow,A234 WPB is a grade in American Standard for carbon steel butt welded fittings.There is also A234 WPC for carbon steel butt welded fittings,but it is not commonly used.

 

Elbows are used to change the direction of the pipe system.A234 WPB elbow is represents carbon steel butt welded elbow.Elbows have two types:equal and reducing.

 

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 is also 45 degree elbow to satisfied different demand.

 

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.

 

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.

 

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.
