High strength: circumferential tensile strength: 320Mpa, axial 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 12-16KV1mm.

　　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. Products that incorporate their service life into domestic and international standards.

　　Good water delivery performance: using vinyl resin, the water quality is excellent, there is no odor, and long-term use does not scale, and does not produce microorganisms under light avoidance conditions.
