Butt Weld Bends

Butt weld elbow is used to change the fluid direction in pipeline systems. There are two types: long radius (LR) and short radius (SR). Butt weld elbows are available in different degrees, including 45 degrees, 90 degrees, and 180 degrees. So, there are:

LR 45 degree butt weld elbow:
45-degree elbow with a long radius (1.5 x Diameter), used to change fluid direction by 45 degrees.

LR 90 degree elbow:
90-degree steel pipe elbow with a long radius (1.5 x Diameter).

SR 45 degree elbow: Short radius (1 x Diameter) elbow in 45 degree, change direction.
SR 90 degree elbow: Short radius (1 x Dia) elbow in 90 degree.

180 degree steel pipe tee
Elbows with a degree greater than 90 degrees are commonly referred to as steel bends. For example, LR/SR 180-degree bends.

The dimensions of butt weld elbows can be specified by the diameter (in NPS) and the thickness according to ANSI standards. For example, a sample specification could be LR 90-degree elbow with a 4-inch diameter and a thickness specified in schedule 40 or schedule 80.
