| Description |
In order to meet the demand of long distance, high pressure, high wear resistance, anti-adhesion, etc, our company develop and produce DN63mm to DN630mm composite pipe, our UHMWPE pipe can composite with sprial welding pipe, high quality seamless pipe, etc.
With the lining thickness of 8mm -20mm, the UHMWPE steel composite pipe not only make full use of the excellent properties of UHMWPE,it also can adapt high pressure, enhance the long distance fieldwork transmission, effectively prevent external destruction,filling the domestic gap in the field of composite pipe, expand the application area
Pressure: 5MPa-32MPa

| Features |
1. High wear resistance
the wear resistance is 4 to 7 times of Q235 steel pipe, 10 times of HDPE, it has the smallest friction coefficient in plastic ranks
2. High impact strength
5 times of oridinary PE pipes, 4 times than HDPE, 2 times of polycarbonate pipe, and 10 times of PTFE pipe
3. Low-energy consumption
high self-lubrication and not adhesion, friction coefficient of only 0.006, the UHMWPE pipe can save energy of 20% under the same flow rate
4. Without scale sediment/no-scale
surface roughness of Ra0.00022, no dirt, no bacterium in long term service
5. High weatherability
the molecular weight of UHMWPE is more than 2 million, as saturated molecular structure, it has strong ability of aging under ultraviolet light , and mechanical properties is stable if not lower than -70℃
6. Cost-saving
small working face, low requirement of foundation, and with the performance of wear-resisting, corrosion resistance, frost resistance and anti-pollution, etc, after the operation, the pipe do not need to make daily maintenance, such as anti-rust and freeze-proofting, descaling, etc, and maintenance cost can be saved by more than 95%.
7. Non-toxic
odourless and high environment protection: it has smooth surface, will not be microbial adhesion in the ocean or sewage engineering, and ensure the stability of water quality
