***HDPE Electro fusion repair saddle pipe fittings features:
1 applies to the same material of the pipe connections;
2 reliable connectivity, high seam strength, air tightness, weldability and stable;
3 injection molding, perfect structure, more secure, reliable, and inexpensive;
4 less susceptible to temperature changes and the impact of human factors;
5 welding process is simple to operate and easy to control, easy construction;
6. Investment in equipment, maintenance costs low.
***HDPE electrofusion bypass saddle pipe fittings function:
Flange connections are the two pipes, fittings or pipes, the first one on each flange is fixed
between two flanges, with flange gasket, bolted together to complete the connection. Some fittings
and equipment have been built flange, also belong to the flange connection. Apply greater pressure
piping systems, with a steel flange fastened outside.
