Light weight, easy to handle: PVC pipes are very lightweight, making transportation, loading, unloading, and construction convenient, thus saving labor costs.
● Excellent chemical resistance: PVC pipes have excellent resistance to acids, alkalis, and corrosion, making them very suitable for the chemical industry.
● Low fluid resistance: The surface of PVC pipes is smooth, resulting in low resistance to fluid flow, with a roughness coefficient of only 0.009, lower than that of other pipe materials, allowing for a reduced pipe diameter at the same flow rate.
● High mechanical strength: PVC pipes have excellent water pressure resistance, external pressure resistance, impact resistance, etc., making them suitable for various piping engineering conditions.
● Good electrical insulation: PVC pipes possess superior electrical insulation properties, making them suitable for wire and cable conduits, as well as electrical wiring in buildings.
● Does not affect water quality: PVC pipes have been confirmed by dissolution tests to not affect water quality, making them the current choice for drinking water pipelines.
● Easy construction: The joining of PVC pipes is quick and easy, resulting in lower construction costs.

●Excellent toughness and impact resistance: Compared with ordinary PVC-U pipes of the same specification, 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 the pipeline during operation.
● Enhanced resistance to environmental cracking: Effectively resists external impact during installation and transportation.
● Improved transportation reliability: PVC-M's high impact resistance 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 improving 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.
