What Are Socket Weld Flanges?

Socket Weld Flanges are designed with a recessed socket bore where a pipe is inserted and fillet-welded at the hub, ensuring a smooth bore and strong connection. They are commonly used in small-diameter, high-pressure piping systems where leak-proof connections are essential.
