Electrofusion Fitting

PE fitting with one or two sockets with heating elements integrated in the inner wall, or with a socket end, which can convert electric energy
into heat energy and weld with pipe or fitting. Its series is SDR9 / 11 / 17; The maximum working pressure is 2.0MPa for water supply supply.

The steeI plate is punched and welded into a tubular reinforced skeleton or polyethylene composite short pipe, which is combined with
polyethylene injection molding fittings, The maximum working pressure s 4.0MPa for water supply supply.
