Product Description A socket weld flange is a type of flange that is used to connect two pieces of pipe together. It is made up of a flange body with a socket, which is a recess that the pipe is inserted into. The pipe is then welded to the flange body, creating a secure connection. Socket weld flanges are typically used in small-diameter pipes, up to 4 inches in diameter. They are a popular choice for applications where internal welding is difficult or impossible, such as in high-pressure or high-temperature systems. Technical Specifications 1.
