Often we see double-wall corrugated pipe and steel double-wall corrugated pipe, some of the difference between the two of us briefly about the next. Double-wall corrugated pipe is d200-800, ring stiffness sn4 and sn8; steel tube is dn300-2400, ring stiffness sn8,12.5,16; double-wall corrugated pipe quality is much better than the quality of steel tube, of course, price also slightly higher. A sub-price goods, and friends can be selected as desired. Steel reinforced polyethylene hdpe double wall corrugated drainage pipe factory --- Luoyang State-run New Materials. Leader: Li Xin 13,014,741,272 15,517,957,863. Steel enhanced PE spiral corrugated pipe is high density polyethylene as the raw material of a new type of light pipes, light weight, high pressure resistance, good toughness, rapid construction, long life and other characteristics, its excellent wall structural design, and Compared to other structural tubing, the cost is greatly reduced. And because the connection convenient, reliable, widely used at home and abroad. Steel reinforced polyethylene hdpe double wall corrugated pipe drains a lot of concrete pipe and cast iron pipe replacement. PE spiral reinforcing steel bellows short-term mass production, can produce large diameter, recyclable, easy to leak, less pollution, lower construction difficulty, high overall performance. Steel reinforced polyethylene hdpe double wall corrugated pipe drainage enhancements PE spiral steel bellows: 1, pressure, impact resistance: for any ground have good adaptability. 2, anti-aging and good: the outer wall is black, can resist ultraviolet prevent aging. 3, chemical resistance: topical coating will not be anything contamination and corrosion. 4, the economy is good: large diameter, lower than the cost of the plastic tube with the specifications. 5, the drainage flow of superior performance: China New material pipe wall smooth, water resistance. Through water power. Contact: Li Tel: 0379-60692511 Mobile: 13014741272 15517957863 QQ: 2778205341 E-mail: 2778205341@qq.com Fax: 0379-65260950 Factory Address: Luoyang Airport Industrial Park
