Lightweight and easy to handle: PVC pipes are very light, making it convenient for handling, unloading, and construction, which can save labor costs.
●Excellent chemical resistance: PVC pipes have outstanding resistance to acids, alkalis, and corrosion, making them very suitable for the chemical industry.
●Low fluid resistance: The inner wall of PVC pipes is smooth, resulting in low resistance to fluid flow, with a roughness coefficient of only 0.009, which is lower than that of other materials. The pipe diameter can be reduced under the same flow rate.
●High mechanical strength: PVC pipes have excellent resistance to water pressure, external pressure, and impact strength, making them suitable for various piping projects.
●Good electrical insulation: PVC pipes possess superior electrical insulation properties, suitable for conduits for wires and cables, as well as electrical piping in buildings.
●No impact on water quality: Tests have confirmed that PVC pipes do not affect water quality, making them suitable for current water supply systems.
●Easy to install: The joining of PVC pipes is quick and easy, resulting in low construction costs.

●Excellent toughness and impact resistance: Compared to regular PVC-U pipes of the same specification, the impact resistance has been significantly improved, allowing for more effective resistance to point loads and uneven foundation settlement.
●Improved water hammer resistance: Effectively resists water hammer, preventing damage during operation.
●Improved resistance to environmental cracking: Effectively resists external impacts on the pipes during installation and transport.
●Enhanced transportation reliability: The high impact resistance of PVC-M overcomes the characteristics of ordinary PVC-U pipes that are prone to wear, scratches, and hidden damage during loading and unloading, which can lead to pressure drop, effectively resisting external impacts and improving transportation reliability and safety.
●Improved adaptability to construction environments: PVC-M high impact resistance water supply pipes have excellent impact resistance and good toughness, allowing them to effectively adapt to construction environments.
