BailianPlastic industry PVC-UDrainage rainwater pipe PVC-UDrainage rainwater pipe
Performance characteristics
1Lightweight, easy to handle and load/unload
pvc-uThe material of the pipe is very light, with a specific gravity of only iron pipe1/5Convenient handling, loading and unloading, and construction can save construction costs.
2Corrosion resistance and excellent drug properties
pvc-uPipes have excellent acid, alkali, and corrosion resistance, making them particularly suitable for the chemical industry, wastewater drainage, sanitary sewers, and other fields.
3. Low fluid resistance
pvc-uThe pipe wall is smooth and has low fluid resistance, with a roughness coefficient of only0.009Compared to other pipes, it has a lower flow rate and does not adhere to scale at the same diameter.
3. High mechanical strength
pvc-uThe pipe has very high water pressure resistance, external pressure resistance, impact resistance, etc., and is suitable for supporting projects under various conditions.
4. Excellent electrical insulation
pvc-uPipes have excellent electrical insulation properties and are suitable as protective sleeves for wires and cables. They can be widely used for wire piping in telecommunications, power matching, and construction.
5. Does not affect water quality
pvc-uThe dissolution test results of pipes and fittings have confirmed that they do not affect water quality, making them an ideal pipe material for current tap water matching.
6. Has good water tightness
pvc-uThe combination of pipes, whether using a flexible socket orTSAt the joint of the socket, it has good water tightness.
7. Easy construction
pvc-uPipe construction is fast and convenient, with low construction costs.
