High strength: circumferential tensile strength: 320Mpa, pull-out tensile strength: 220Mpa (strength can be designed according to needs)
High stiffness: resin quartz sand sandwich structure. 1250, 2500, 3750, 5000, 10000N/M and above.
Anti leakage: Equipped with a resin inner lining layer and a high-density structural layer, it prevents leakage both inside and outside.
Lightweight: Generally only 1/4 of steel pipes of the same diameter and 1/10 of cement pipes, with low installation costs.
Corrosion resistance: It has excellent corrosion resistance and can transport corrosive media and any sewage.
Electrical insulation: breakdown voltage 12-16KV/mm.
Smooth inner wall: The hydraulic friction coefficient is small and stable for a long time, with considerable energy-saving benefits.
Good frost resistance: water does not freeze or crack after freezing.
Good insulation performance: The thermal conductivity is only 1/233 of that of steel pipes.
Long service life: designed for 50 years. Only products that incorporate the service life into domestic and international standards.
Good water delivery performance: using vinyl resin, with excellent water quality, no odor, and long-term use without scaling,
No microorganisms are produced under light avoidance conditions.
