Lightweight and easy to handle: PVC pipes are very light, making them convenient for transportation, loading and unloading, and construction, thus saving labor costs.
● Excellent chemical resistance: PVC pipes have excellent resistance to acids, alkalis, and corrosion, making them very suitable for chemical industry applications.
● Low fluid resistance: The smooth surface of PVC pipes results in low fluid resistance, with a roughness coefficient of only 0.009, which is lower than that of other pipes, allowing for a reduction in pipe diameter under the same flow rate.
● High mechanical strength: PVC pipes have excellent resistance to water pressure, external pressure, and impact, making them suitable for various piping projects under different conditions.
● Good electrical insulation: PVC pipes possess superior electrical insulation, making them suitable for conduits for wires and cables, as well as for electrical piping in buildings.
● No impact on water quality: Tests have confirmed that PVC pipes do not affect water quality, making them a suitable material for current water supply piping.
● Easy to install: The joint construction of PVC pipes is quick and easy, leading to low construction costs.

●Excellent toughness and impact resistance: Compared to ordinary PVC-U pipes of the same specification, the impact resistance is significantly improved, allowing for better resistance to point loads and uneven foundation settlement.
● Improved water hammer resistance: Effectively resists water hammer, preventing damage to the pipelines during operation.
● Enhanced resistance to environmental cracking: Effectively resists external impacts during installation and transportation.
● Increased transportation reliability: PVC-M with high impact resistance overcomes the issues of ordinary PVC-U water supply pipes, which are prone to wear, scratches, and hidden damages during loading, unloading, and transportation, thus effectively resisting external impacts and improving transportation reliability and safety.
● Improved adaptability to construction environments: PVC-M high-impact water supply pipes possess excellent impact resistance and good toughness, allowing them to effectively adapt to construction conditions.
