" Pvc-u double axial hollow pipe" is made of hard polyethylene (pvc-u) resin as the main raw material. The necessary processing AIDS are added and extruded. The production of double layer axial hollow drain pipe" USES non-toxic PVC resin and stabilizer to meet the requirements of hygienic performance, which will not cause secondary pollution The pipe material is suitable for underground sewage discharge, drainage and unpressurized farmland drainage in municipal engineering, outdoor public buildings and residential areas, and also for industrial sewage discharge and drainage pipes.

1. Corrosion resistance
Good chemical stability, free from environmental factors and media components in the pipeline, good corrosion resistance. Low thermal conductivity, low thermal conductivity, thermal insulation, good energy efficiency.
2. Aging resistance
Good hydraulic performance, smooth inner wall of the pipeline, small resistance coefficient, no scaling, no change in circulating area of the pipe with time, and low probability of pipe obstruction.
3. Impact resistance
Compared with metal pipe, the density is small, the material is light the transportation is convenient, the installation is convenient,flexible, simple, the maintenance is easy. Sn6-sn16 can be realized with good mechanical performance, impact resistance and high level of ring stiffness.
4. Does not burn
Flame retardant model, no combustion, no combustion-supporting.
5. Noise and noise reduction
Good acoustic insulation. The method of noise reduction can improve the phrenic effect of pipeline material. The structural wall pipe is developed based on this idea. Under the same conditions, the noise measurement results of different types of drainage plastic.
Pipes were as follows: > core foaming pipe > hollow wall pipe > spiral pipe > structural wall pipe.
6. Quick installation
The installation is convenient and fast. The connection mode is adhesive type and elastic sealing ring type, After the main pipe is installed, water can be supplied within 24 hours.
