Product Overview
Reducing Socket Weld Elbow 45°
Overview
A Reducing Socket Weld 45° Elbow is a high-integrity industrial pipe fitting designed to simultaneously change the direction of a pipeline by 45 degrees while transitioning between two different pipe sizes. Unlike standard elbows, reducing socket weld fittings feature recessed areas (sockets) of varying diameters, where pipes are inserted before being secured with a fillet weld, offering high mechanical strength, space savings, and leak-proof performance for small-diameter, high-pressure piping systems.
- Designed specifically for high-pressure and hazardous fluid containment, minimizing the risk of joint failure across changing pipe diameters.
- The pipes slide directly into the socket recesses, making alignment during installation much simpler than aligning butt-weld reducing joints.
- When installed properly with a small expansion gap, it provides smooth internal flow characteristics even as the line size scales.
- The 45-degree angle provides gentle directional changes and size transitions compared to 90-degree reducing elbows, reducing pressure drop in tight piping layouts.
