Steel Plastics Sprial Pipe

Details： Product features (1) Light weight, high ring stiffness, low cost, with strong market competitive power. Under the same diameter and ring stiffness, the lightest weight per meter can be obtained for the pipe over 800 mm of diameter and materials can be cut down by 20%－60% in comparison with those of the hollow winded pipe, the molding ribs winded pipe and the double wall corrugated pipe. (2) Easy and reliable connecting, by thermo-melt coupling (for the purposes of drainage, sewerage and ventilation) or thermo-shrinking film, or outer half-block with sealing rings. (3) Excellent low temperature resistance, being installed between －60℃？ 60℃． (4) High complete strength, bearing large axial tensile force and circumferential ring stress. (5) Good soil adaptability. It has a good adaptability without breaking for resisting earth settlement and movement because of high coefficient at rupture which is up to 500%. (6) Excellent flowing performance. The flow is bigger
