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:

Pipeline network in extremely cold areas
Stable sealing in a low-temperature environment of -40ºC

Highly corrosive environment
Protection against acidic and alkaline media in chemical industrial parks

Geological unstable zone
Tensile interface in soil layer settlement area

Uninhabited areas in the wild
There is no construction of power supply infrastructure

High-temperature steam pipeline
Reinforcement of the 120ºC heat supply network
