Butt fusion can be used for jointing pipes and fittings 63mm diameter and larger. Since the small diameter pipes’ wall thickness are too thin to butt welding, so the diameter less than 63mm, and the diameter from 63mm to 110mm could be used be socket fusion methods and compression fittings, which are more easy to install. Which are most commonly used for jointing pipes less than 110mm pipes, suit to both coiled pipes and straight pipes.

Socket fusion fitting including the elbow, tee, coupler, reducer, end caps, and stub ends, ball valves, it is more cost-effective and easy installation methods, please see our socket fusion fittings table to find all the fittings you will need.

The socket fusion technique consists of simultaneously heating both the external surface of the pipe end and the internal surface of the socket fitting until the material reaches the recommended fusion temperature, inspection of the melt pattern, insertion of the pipe end into the socket, and holding it in place until the joint cools. Mechanical equipment is available to hold both the pipe and the fitting and should be used for sizes larger than 2" CTS to help attain the increased force required and to assist in alignment. The procedures in ASTM International F 2620 are applicable.

Bingo Pipeline, we not only provide the socket fusion fittings, but also provide the socket fusion welding for your options.
