1, excellent chemical corrosion resistance: PVC-U pipe has excellent acid and alkali resistance, corrosion resistance, for chemical industry, waste water discharge, health sewer and other purposes, more suitable. It can resist the corrosion of alkaline soil containing sulfate and carbonate. High impact strength: the hydraulic strength, external pressure strength and impact strength of PVC pipe are very high, which is suitable for pipe distribution engineering under various conditions. The construction is convenient, and the requirement of backfill is not high; In the municipal road engineering, it is not easy to deformation due to extrusion, and the comprehensive cost is low;

2, beautiful appearance and generous: UPVC drainage pipe appearance is white, bright and smooth, beautiful, bright color, can add a clean and light sense of The Times to the building indoor environment atmosphere. Simple construction: PVC pipe and pipe fittings using solvent adhesive connection, joint construction is quick and easy, construction cost is low.

3. Low comprehensive cost: 20-30% lower than the comprehensive cost of the cast iron piping system with the same specifications. Good environmental protection: PVC is an environmental protection product, can be recycled and reused, will not cause any pollution to the environment. Good sound insulation and noise reduction: with good noise reduction characteristics, can significantly reduce noise pollution. The silencing effect is more than 10dB. Smooth inner wall low fluid resistance: PVC-U pipe has smooth wall, low flow resistance, roughness coefficient 0.009, lower than other pipes, larger flow under the same diameter, and no scale attached, pipeline is not easy to block.

4. Long anti-aging service life: the elastic modulus of PVC-U pipe changes little with time, ensuring the long-term service performance of the pipe; Designed service life of more than 50 years; PVC-U strong resistance: it can effectively resist the penetration and penetration of plant roots.
