SOCKET WELD FITTINGS

Socket weld fittings are connected to pipes by fillet welds, whereas threaded fittings are screwed onto the pipe (or vice-versa).

A socket weld fitting (left side) and a threaded fitting (right side).

Socket weld fittings are used for applications where strong and long-lasting connections are required.  Socket weld fittings are very reliable but are time-consuming to install in a piping system (due to the heavy workload caused by welding operations on small parts).

Socket weld fittings are available in sizes from 1/8 to 4 inches and in classes between 2000# and 9000#.

The typical applications for socket weld fittings are:

• Steam

• Explosive fluids and gases

• Acids and toxic fluids

• Long service / durable installations
