ASTM A234 WPB B16.9 L/R Carbon Steel Butt Welding 90 Degree Elbow
ASTM A234 WPB B16.9 L/R Carbon Steel Butt Welding 90 Degree Elbow
A carbon steel butt welding 90-degree elbow is a type of pipe fitting used to create a 90-degree bend in a piping system.
Material:
- The 90-degree elbow is made from carbon steel, typically conforming to standards such as ASTM A234 WPB or ASME B16.9.
- Carbon steel provides high strength, durability, and corrosion resistance.
Dimensional Standard:
- The dimensions and tolerances of the carbon steel 90-degree elbow follow established standards, such as ASME B16.9.
- This ensures compatibility with other piping components and proper fit in the system.
Welding:
- The 90-degree elbow is designed for butt welding connections, providing a strong and reliable joint.
- Butt welding ensures a seamless and leak-free transition between the elbow and the connected pipes.

ASME B16.9 L/R Elbow Dimensions
The ASME B16.9 elbow is used when a pipe changes direction. Elbows can turn up, turn down, turn left, right, or any angle in between. The long radius (L/R) elbows denote elbows with the center-to-end dimension of 1.5D radius which equals to 1.5 x NPS in inch unit. The standard long radius elbows of ASME B16.9 can be further classified as 90° and 45° according to the angle of the flow-direction change.
