● FRPP Bellows: higher contrast PE corrugated pipe ring stiffness, more reliable ● resistance to external shocks and strong: when external shocks force, to restore and superior performance, in the case of ground subsidence will not break. ● excellent chemical resistance: acid, alkali, corrosion resistance. ● excellent wear resistance: more than steel, cast iron pipes, cement pipes resistant to wear. ● Fluid resistance: smooth wall, small fluid resistance of the drainage speed, large capacity through the water. ● Physical performance and stability: anti-aging, when the surface is not affected by direct sunlight. ● Light weight: Light weight, transport, easy connection, short construction period, easy management and maintenance. ● environmental impact: non-toxic, harmless to land, can be recycled. ● steel enhanced PE spiral corrugated pipe superiority than PE double wall corrugated pipe for more information details, please visit: http: //www.huatong999.com
