PVC double wall corrugated pipe factory direct, high-quality large-diameter pipes spot wholesale

PVC is characterized by large-diameter pipes of large diameter PVC drainage pipe is a kind of high-density polyethylene (HDPE) as raw materials, welded pipe wrapping. Because of its unique molding process, it can produce up to 500mm diameter of large diameter pipe. This pipe has good flexibility, long life, light weight, corrosion resistance, abrasion resistance, and good low temperature impact properties, municipal drainage, sewage and industrial effluents, sewage quality pipe. Features: 1. Light weight, convenient transportation and handling: PVC pipe material is very light, convenient transportation, handling, construction, saving labor. 2. Excellent chemical resistance: PVC pipe has excellent resistance to acid, alkali, corrosion resistance, the use of the chemical industries apply. 3. The flow resistance is small: the smooth wall PVC pipe, fluid resistance, the roughness coefficient is only 0.009, lower than other pipe, at the same flow rate, the diameter can be reduced. 4. Mechanical strength: high pressure strength of PVC pipe, pressure-resistant strength and impact strength are all very high, suitable for plumbing under various conditions. 5. Electrical insulation: PVC pipe has excellent electrical insulation properties, suitable protective sleeve. 6. does not affect the water quality: PVC pipes and fittings by dissolution experiments show no affect on water quality, water piping for the current pipe.
