HDPE Solid Wall pipe is a high-quality high-density polyethylene resin as the main raw material, add the appropriate additives, and processed by extrusion molding a high-tech products. The product is resistant to corrosion, aging, shock, high mechanical strength, long life, excellent electrical insulation properties and performance characteristics, can be widely used in the field of buried high voltage cable, street lighting cable protection casing.
Widely used in urban road construction, residential development, landscape, corporate construction places such as electricity, street lamps, lawn lamps, garden lights, intelligent, cable TV, communications, intelligent transportation threading of the cable sheath tube.
Excellent physical properties of high-quality polyethylene raw material production. Not only has excellent stiffness, strength, and also has good flexibility. Conducive to the installation of the pipeline
Corrosion resistance, Electrical insulation performance ,long service life. In coastal areas, groundwater levels, land humidity. The use of metal or other pipe must be corrosion, and the life-expectancy is only 30 years, resistance to HDPE pipe can withstand a variety of chemical media, free from the effects of soil erosion，and the life-expectancy 50years.
Toughness, deflection good HDPE pipe is a high-toughness pipe, the elongation at break of more than 350%. On the basis of uneven ground subsidence and dislocation ability to adapt is very strong. Resistance to shock.
Light weight, maintenance, installation and construction, easy maintenance, easy to transport and operate.
Small-diameter pipe can be used coil form of long pipe sections, fittings, easy installation.
The pipe can be made into a variety of colors to be identified.
Low temperature brittleness of low-temperature impact performance of HDPE is very low, -20℃-40℃ temperature range of safe use. Winter construction, material impact, not pipe brittle fracture occurs. Good wear resistance, HDPE pipes and other metal pipe.
Four times the abrasion resistance of the metal tube.
A variety of new construction. HDPE pipe construction in addition to traditional excavation using a variety of new trenchless technology, such as the top tube. Construction, one of this place does not allow excavation, is the only option.
