HDPE Seamless Electrofusion Sleeves Welding For Pre Insulated Pipe

The new process solves the problem of natural heat shrinkage:

The advantages of Huashida seamless electrofusion sleeves:

Construction without power supply:
Welding can be done by baking with a flame gun.  It is suitable for outdoor environments without electricity.

Strength increased by 20%:
The biaxially oriented HDPE base material has superior strength to the pipe base material.

100% passed the airtight test:
Special rubber strips combined with irradiation memory effect offer sealing performance far exceeding that of traditional processes.

Deformed port compatibility:
Heat shrinkable tape or electric heating network can be superimposed to assist in reinforcement, ensuring the reliability of the seal.

Minimalist and efficient operation:
Workers can be on the job after short-term training, eliminating the cost of power supply engineering vehicles.

Application:

Field construction without electricity:
Welding in areas without power supply in deserts and plateaus

Emergency port repair:
Quick repair of deformed or damaged pipes

Anti-corrosion sealing reinforcement:
Double protection against corrosion in the chemical industrial area

Connection of insulation pipes:
Thermal sealing of polyurethane insulated pipes

Cross-border long-distance pipeline:
Designated pipe fittings for cross-border energy projects
