Lightweight and convenient for handling: PVC pipes are very light, making them easy to transport, unload, and install, which can save 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 resistance to fluid flow, with a roughness coefficient of only 0.009, which is lower than that of other pipe materials. Under the same flow rate, the pipe diameter can be reduced.
●High mechanical strength: PVC pipes exhibit good 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 properties, making them suitable for conduits for wires and cables, as well as for electrical wiring in buildings.
●Does not affect water quality: PVC pipes have been verified through dissolution tests to not affect water quality, making them the current choice for drinking water piping.
●Easy installation: The joining process of PVC pipes is quick and easy, resulting in low construction costs.

●Excellent toughness and impact resistance: Compared to ordinary PVC-U pipes of the same specifications, the impact resistance is significantly improved, effectively resisting point loads and uneven foundation settlement.
●Improved water hammer resistance: Effectively resists water hammer, preventing damage to pipes during operation.
●Enhanced resistance to environmental cracking: Effectively resists external impacts during installation and transportation.
●Improved transportation reliability: The high impact resistance of PVC-M overcomes the susceptibility of ordinary PVC-U water supply pipes to wear, scratches, and hidden damage during loading, unloading, and transportation, effectively resisting external impacts and enhancing transportation reliability and safety.
●Enhanced adaptability to construction environments: PVC-M high impact water supply pipes possess superior impact resistance and good toughness, effectively adapting to construction environments.
