A Welded Elbow is a pipe fitting manufactured by forming and welding processes,designed to change the direction of fluid flow in piping systems.It is mainly produced in 45°and 90°angles and connected to pipelines by welding,ensuring strong,tight,and durable joints for pressure and medium transmission.
Types
Butt Welded Elbow
Most common type,with beveled ends for direct butt welding to pipes.
Long Radius(LR)Welded Elbow(1.5D)
Gentle curvature,low flow resistance,suitable for high-flow and high-pressure systems.
Short Radius(SR)Welded Elbow(1D)
Compact structure for space-limited installations.
Seamless Welded Elbow
Made from seamless steel pipe,higher strength and pressure rating.
Welded Fabricated Elbow
Made by rolling and welding steel plates,cost-effective for large-diameter pipelines.
