Product Overview

Socket Weld Elbow 45°

Overview

A Socket Weld 45° Elbow is a high-integrity industrial pipe fitting designed to change the direction of a pipeline by 45 degrees. Unlike butt-weld fittings, socket weld fittings feature a recessed area (the “socket”) where the pipe is inserted before being secured with a fillet weld, offering high mechanical strength and leak-proof performance for small-diameter, high-pressure piping systems.
