Five, HDPE pipe long service life, more than 50 years of safe use of PE pipe is more than 50 years, it has been proved not only international standards and new international, and has been proven in advanced countries. Cement pipe theoretically life of 20 years dn200 double-wall corrugated pipe, but as silicates, has long been acid corrosion, life greatly reduced. Cement pipes all over the country because the sewage leak lead to ground subsidence, the interface fracture within a few years would have to replace the instance. Six HDPE pipe inner surface is smooth, with no sign of nuclear power, not scaling cement pipes easy to scale, after scaling, so that the diameter narrowing, affecting through traffic. HDPE double-wall corrugated drainage pipe is polyethylene resin as the main raw material, adding an appropriate amount of additives, the extrusion for building outdoor drainage and sewerage municipal new pipe. Light weight, small drainage resistance, high compressive strength, corrosion resistance, easy construction, etc., is an ideal material replace the cast iron pipes and cement concrete pipes. HDPE pipe than concrete structural wall intubation showing a more economic and social benefits, greatly shorten the construction period and reduce the difficulty of construction due to the double wall corrugated HDPE pipe quality is far lighter than cement pipe wall bellows, very easy socket, so greatly reducing the difficulty of construction; and double wall corrugated HDPE pipe a minimum of 6 meters, and 2.5 meters a cement tube, greatly shorten the construction period. Two, HDPE double wall corrugated pipe cement pipe on the ditch due to less demanding steel pipe hbpe double wall corrugated pipe, in order to ensure socket effect, the ditch must deal with a flat wall corrugated pipe pvc, the best foundation layer, and It requires construction workers have absolute responsibility. HDPE double wall corrugated pipe is a flexible pipe, to ditch ask for much. Double-wall corrugated pipe pvc, double-wall corrugated pipe, Xiong Yu-tai (View) by Xiong Yu-tai plastic factory.
