Butt Weld Elbow

Steel Pipe Elbow for Industrial Piping Systems

Overview

Butt Weld Elbow is a pipe fitting used to change the direction of flow in piping systems by welding directly to the pipe ends.
It provides a smooth and continuous flow path, reducing turbulence and pressure loss, and is widely used in oil & gas, petrochemical, power generation, shipbuilding, and industrial pipelines.

Butt weld elbows are available in 45°, 90°, and 180° angles, with long radius (LR) and short radius (SR) designs to meet different installation requirements.
