Our Advantages

 

1. The scope of application:
       Applicable to a variety of caliber, but need to be combined according to the market supply capacity, but in accordance with according to the relevant standards (CJJ101/63) requirements of the pipe outer diameter DN ≤ 90mm pipe should be used electrofusion connection.
2. The welding principle
      It belongs to the same socket welding method, but the difference is that the welding heat generated by the resistance wire energized heat, energized process of molten material flow and pressure generated in the fusion surface makes the molten welding surface molecular chain entanglement, welded together.

 

Appliation Cases

 

Zoucheng City Urban Water Supply Capacity Enhancement Project
 The project is 3,000 meters long, using Donghong DN800MM, 900mm steel wire mesh skeleton polyethylene composite pipe. All adopt the electrofusion connection method, simple operation, fast construction speed.Service life up to 50 years.
