Frequently Asked Questions on Socket Weld Fittings
Key engineering, tolerance, and international compliance answers from our metallurgical quality desk.
Socket weld fittings have a socket that the pipe inserts into before welding, making them ideal for small bore (up to 4 inch) high-pressure applications. Butt weld fittings are welded directly to the pipe end and are used for larger diameter pipes.
