PE100 is the third generation of PE resin, having the double peak molecular weight distribution and its comonomer is the priority to be placed in the longer molecular chain, therefore, it has stronger density and rigidity, PE100 maintains good the anti-creeping capability at 20 Degrees Celsius for 50 years while keeping good ESCR performance.

With its excellent capability to resist the slow crack growth, excellent capability to resist fast crack expansion and good improvement of sensibility to scratches, the pipe made from PE100 could have higher long term static pressure strength.

Application scope of HDPE pipe:

Rural and urban tap water system
Urban gas conveying pipe
Able replace the concrete pipe, cast iron pipe and steel pipe
Industrial material conveying pipe.
Water supply pipe for garden greenization
Pipes for discharge of wastewater
Conveyance of ores and sludge
Pipes for agricultural irrigation
Marine pipes.
Pipes for seawater desalination
Rural biogas pipe

Ground-source heat pump system is a kind of piping system requiring higher safety level.

The most popular configurations for the ground source heat pump system is vertical pipe burying. The vertical pipe burying requires vertical drilling in the ground(the burying should be within 200 meters depth underground, and also may adopt reinforced concrete pile foundation. )Due to the great depth of burying and inconvenience for daily maintenance after operation, the ground source heat pump system has very hiher requirements for various indexes of pipe materials.

2. Ground source heat pump pipe materials

Professional system configuration

Our company always adhere to the ISO standard and strict outgoing product test system in the manufacturing process of pipes and its fittings to ensure excellent quality of pipe system.

Safe connecting mode

The adoption of heat fusion and electric fusion is safe enough to avoid any leakage.

Test demonstrates that u-pipe ground source heat pump PE pipe has excellent anti-peeling performance (de-bonding test- ISO13954, extrusion de-bonding test-ISO 13955)
