HDPE double wall corrugated pipe HDPE double wall corrugated pipe performance and features double-wall corrugated HDPE drainage pipe is polyethylene resin as the main raw material, adding the right amount of additives, extrusion molding, suitable for outdoor building with drainage and municipal sewage new pipe. Light weight, small drainage resistance, high compressive strength, corrosion resistance, easy construction, etc., is an ideal material to replace cast iron pipes and cement concrete pipes. A greatly shorten the construction period and reduce the difficulty of construction due to the quality of HDPE double wall corrugated pipe is far lighter than cement pipes, very easy socket, it greatly reduces the difficulty of construction; and HDPE double wall corrugated pipe a minimum of 6 meters, and cement pipes to 2.5 meters a greatly shorten the construction period. Two, HDPE double wall corrugated pipe for ditch less demanding because of the cement pipe for steel pipe, to ensure the socket effect, ditch must deal with a flat, preferably laying the foundation layer, and require construction workers have absolute responsibility. HDPE double wall corrugated pipe is a flexible tube, do not ask for the ditch. Three, HDPE pipe to ground subsidence or changes in the earth's crust without breaking elongation of HDPE pipe steel tube 20 times, six times that of PVC half, its elongation at break is very high, extending strong. This means that when the next issue of local surface subsidence or seismic changes in the earth's crust have a case, HDPE pipe can produce resistance to deformation without fracture. This is far superior to the pipe, but also significantly better than the brittle PVC pipe. Four, HDPE pipe penetration is much lower than cement pipe, less than 2%, will not cause secondary pollution of groundwater cement pipe inelastic, although with apron, but the seal is poor, especially construction workers due to heavy cement pipes bad construction, regardless of socket simply the effect of lead apron out of action, so that the pipe penetration increased. Fifth, the safe and long life of HDPE pipe, PE pipe over 50 years for more than 50 years, the life of 20-year-cement pipes in theory, but it is a silicate-based, long-term corrosion by the acid-base, life is greatly reduced. Cement pipes all over the country due to water leakage cause ground subsidence, the interface fracture, within a few years had to replace instances. Six inner HDPE pipe surface is smooth, with no sign of nuclear power, no scaling cement pipes easy to scale, after scaling, so that the diameter narrowing, affecting through traffic. Seven, light HDPE quality, easy to transport and install, no pipe quality cement weight loss is not easy to transport and install, and easy to wear and tear during transportation and installation. Eight, when the flow through the pipeline, with the same slope and depth, HDPE can be compared to a surface roughness factor of two types of small cement pipe HDPE 0.009, cement pipe surface roughness coefficient of 0.014, according to the world's only law recognized Xie conduct with the flow calculation, HDPE pipe can be smaller than the two types of cement pipe, but the practical application, the proposed model can be a small one. Designed as a 600-diameter HDPE cement pipe can be used to replace 500 caliber.
