PVC double wall corrugated pipe a unique performance characteristics of structure, high strength, smooth wall, small friction, large circulation, infrastructure need to do concrete foundation, light weight, easy handling and installation, quick construction; rubber ring socket connection method reliable, easy construction quality assurance; flexible interface. Anti-differential settlement capability; good anti-leakage effect, can be resistant to many aggressive chemical media; without fouling the tube, the basic need to dredge, buried life of five years or more. Second, the production process pvc double wall corrugated pipe is rigid PVC as the main raw material, pvc double wall corrugated pipe respectively, by the inner and outer extrusion, molding, wall smooth, trapezoidal corrugated wall, sandwiched between the inner and outer walls the walls of the hollow plastic tubing. Third, the application field of a municipal project. Can be used for drainage, sewage two construction projects. For building rainwater pipes, underground drainage, sewage, ventilation tubes, etc. 3, electrical telecommunications engineering. Available for a variety of power cable protective tube 4, railways, highways communications. Used as communication cable protection tube 5 industries. pvc double wall corrugated pipe is widely used in chemical, pharmaceutical, and other industries surrounded sewage pipes 6, agriculture, garden projects. Farmland, orchards, tea plantations and forest irrigation 7, road works. pvc double wall corrugated pipe used for railway, highway infiltration, drainage 8, mine. pvc double wall corrugated pipe do mine ventilation, water to drain PVC-U double-wall corrugated pipe OD Series Unit: mm nominal diameter 110 160 200,250,315,400,500 minimum average inner diameter of 97 135 172,216,270,340,432 jack length ≥60 ≥81 ≥99 ≥125 ≥132 ≥150 ≥180 Note: pipe length is 6 m / root. Physical and mechanical properties of the project indicators ring stiffness SN4 ≥4KN / m SN8 ≥8KN / m impact strength TIR≤10% ring flexible sample sleek, no reverse bend without cracking, opening between two walls oven experimental non-hierarchical, non-cracking continuous seal without leakage of methylene chloride immersion test without separating the inner and outer wall, the inner and outer surfaces of change is not inferior to 4L Our company mainly produces a variety of Plum PE, PVC bellows, PVC solid wall PVC pipe PVC pipe threading bellows.
