PVC composite pipe is a new compound drainage pipe. The pipe is three-layer co-extruded composite drain pipe, the inner and outer wall is rigid PVC, in order to ensure the pipe of sufficient strength and other physical properties, the middle layer is made of specially formulated PVC, the relative density of 0.7-0.9g/cm3, the closed-layer structure for the micro-hole-like. This special structure,cleverly use the type Ⅰ structural principle of material mechanics . Intermediate sandwich that can be observed under the micro is the soft body, which not only has the PVC (air-wall) pipe all the advantages, as well as sound insulation, heat insulation, shock, shock, and light and cheap is better than other solid wall pipe features.

1.light weight (density 0.9-1.2g/cm3), low price.
2.wall smooth,small friction coefficient and improve the efficiency of fluid transport.
3.high shock resistance strength, rigidity of its ring as ordinary PVC-U 2 times.
4.good weather resistance, can be used in -30 ℃ -70 ℃, and when the temperature changes the pipe size is of good stability .
5.special complex multi-layer structure, greatly improving the performance of pipe insulation.
6.Spontaneous self-extinguishing properties of strong.
7.has excellent corrosion resistance.
8.To improve the life of the pipeline, the pipeline is 4-7 times the normal.
9.Composite drain pipe lower than the average cost of installation, coupled with its resistance to corrosion, abrasion, weather and many other factors contrast, higher than the average performance of polyethylene pipe.
