Seven HDPE light weight, easy to transport and install, without loss of quality cement pipe weight, 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 the surface roughness coefficient cement pipes HDPE small one or two models 0.009, cement pipe surface roughness coefficient of 0.014, only in accordance with the laws of the world recognized Xie, performed with flow calculation, HDPE pipe can be smaller than the two models pvcu cement pipe wall corrugated pipe, and practical applications, it is recommended small a model number. Designed as a 600-diameter concrete pipes can be used to replace HDPE 500 caliber. Three, HDPE pipe on the ground subsidence or changes in the crust without breaking elongation of HDPE pipe steel tube 20 times, six times a half is PVC, which is very high elongation at break pe double-wall bellows, extension of it strong. This means that the local surface sink or when there are changes in the earth's crust recurrent earthquake situation, HDPE pipe can become resistant to deformation without breaking. This is far superior to steel, also better than the obvious fragility of PVC pipe. This performance has been proven at home and abroad (Japan's Kobe earthquake did not cause pipe rupture; HDPE pipe in support of South Baoshan earthquake damage is not proven). Four, HDPE pipe penetration is far lower than the cement pipe wall corrugated pipe d300, less than 2%, will not cause secondary pollution of groundwater cement pipe inelastic, although with a gasket, but the sealing effect is poor, especially in construction Due to heavy cement pipe workers, poor construction, regardless of the socket simply the effect, resulting in the loss of the role of the apron, so that the pipe increased penetration. Double-wall corrugated pipe specifications, double-wall corrugated pipe, Xiong Yu-tai (View) by Xiong Yu-tai plastic factory.
