Product Structural Features

1. Lightweight: PVC-U is only 1/10 the weight of cast iron, making it easy to transport and install, reducing costs.
2. Superior Chemical Resistance: PVC-U has excellent resistance to acids and alkalis, with the exception of strong acids and alkalis near their saturation point.
3. Durable: PVC-U offers excellent weather resistance and is resistant to corrosion by bacteria and fungi.
4. Non-conductive: PVC-U is non-conductive and is not susceptible to corrosion by electrolysis or electric current, eliminating the need for secondary processing. It is non-flammable and does not support combustion, eliminating fire safety concerns.
5. Low resistance and high flow rate: The smooth inner wall minimizes fluid flow loss, and dirt is less likely to adhere to the smooth pipe surface, making maintenance simple and cost-effective.
6. Easy Installation and Low Cost: Cutting and joining are simple. PVC glue has proven to be safe, reliable, easy to use, and cost-effective.
