✅ Socket Weld Threaded 90° Elbow – High Performance Forged Steel Pipe Fittings

SSM supplies premium quality Socket Weld Threaded 90° Elbows, designed for reliable pipeline direction changes, high-pressure connections, and compact piping solutions in industrial, hydraulic, instrumentation, oil & gas, and process piping systems.

Manufactured from high-quality forged carbon steel, stainless steel, and alloy steel materials, these elbows provide excellent mechanical strength, corrosion resistance, and long service life in demanding operating environments. The combination of socket weld and threaded connection designs offers installation flexibility, allowing secure connections in systems where welding and threaded assembly methods are both required.

With precision forging, accurate socket dimensions, and high-quality thread machining, Socket Weld Threaded 90° Elbows ensure excellent sealing performance, reliable flow direction control, and durable operation in high-pressure piping applications.

✅ Product Overview

A Socket Weld Threaded 90° Elbow is a forged pipe fitting designed to change the direction of a pipeline by 90 degrees. It combines a socket weld end on one side and a female threaded connection on the other side, providing a versatile connection solution for different piping configurations.

The socket weld design allows the pipe to be inserted into the fitting socket and welded externally, while the threaded end enables quick connection with male threaded pipes, valves, or fittings.

Compared with butt weld elbows, socket weld threaded elbows are more compact and easier to install, making them widely used in small-diameter, high-pressure piping systems.
