PVC three-layer co-extruded composite pipe production line

Consultation

PVC composite pipe is a new type of composite drainage pipe. The pipe is a three-layer co-extruded composite drain pipe, and the inner and outer walls are made of rigid PVC to ensure sufficient strength and other physical properties of the pipe. The intermediate layer is made of specially formulated PVC, and the relative density is 0.7-0.9 g/cm3. The layer structure is micro-closed pores. This special structure subtly utilizes the I-structure principle in material mechanics. Microscopically, the middle interlayer can be observed, which is a soft colloid, which not only has all the advantages of PVC (empty wall) pipe, but also has better sound insulation, heat insulation, shock resistance, impact resistance, light weight and cheaper than real wall pipe. specialty.

1. Light weight (density 0.9-1.2g/cm3), low price.

2. The inner wall is smooth, the friction coefficient is small, and the fluid transport efficiency is improved.

3. High impact strength, its ring steel is twice that of ordinary PVC-U

4. Good weather resistance, can be used at -30 ° C -70 ° C, and the tube size stability is good when the temperature changes

5. Special composite multi-layer structure, greatly improving the sound insulation performance of the pipe

6. Self-ignition self-extinguishing performance

7. Excellent corrosion resistance

8. Increased pipe life, 4-7 times that of ordinary pipes

9. The installation cost of the composite drain pipe is lower than that of the general pipe, and its corrosion resistance, wear resistance, weather resistance and other factors are comprehensively compared, which is higher than ordinary polyethylene pipe.
