What is the difference between a Buttweld and a socket weld?

Category: Buttweld

Buttweld fittings are used for larger pipe sizes where high pressure and temperature are involved, while socket weld fittings are used for smaller pipe sizes and low-pressure applications. Buttweld fittings are joined by welding, while socket weld fittings are joined by inserting the pipe into the socket and then welding the joint.
