HDPE Seamless Electrofusion Sleeves Production line for Pipe joint sealing

Construction technology of seamless electrofusion sleeve

Material and structural advantages:

High-strength base material
Made from high-quality HDPE (high-density polyethylene) raw materials and processed by biaxial stretching technology, the thickness of the pipe fitting base material is consistent with that of the pipe base material (customizable from 3 to 18mm), but the strength is increased by more than 20%, and the tensile and shear resistance are significantly enhanced.

Irradiation memory performance
During the production process, it undergoes irradiation treatment. When heated, it rapidly shrinks and closely adheres to the main tube, forming a "dead lock" seal, with a density far exceeding that of traditional electrothermal fusion sleeves.


The new process solves the problem of natural heat shrinkage:

Our Advantages

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
