Advantages:
1. Economic: with low cost than other same specifications plastic pipes, lightweight, transportation, construction, management and maintenance of provinces expenses is convenient, large diameter, ring high stiffness
2. Excellent corrosion resistance: will not be sewage and waste water and chemical corrosion and will not be soil rot in material and corrosion, also will not be plant root destruction
3. Aging resistance: pipe is commonly black and can withstand piled up and construction process for sunlight straight bask in
4. Wear-resisting superior performance: than steel tube, iron pipes, cement tube wear resistance
5. Drain liquidity superior: tube wall flow resistance small, drainage speed, the post-coiling water ability strong, large flow
Applications:
Civil engineering
Agricultural irrigation
Conveying system for sewage plant
Pre-buried piping under highway
Ventilation piping for chemical industry and mine
Power telecommunication cable conduit
Bridge construction
