Differences between PVC-U and PVC-C pipes
Thread Content
What are the differences between PVC-U (rigid polyvinyl chloride) pipes and PVC-C (chlorinated polyvinyl chloride) pipes in terms of corrosion resistance, operating temperature, weather resistance, strength, stiffness, and price?
PVC-U pipes and PVC-C pipes differ in several aspects: 1. Corrosion resistance: Both possess good corrosion resistance, but PVC-C has superior corrosion resistance and can withstand a wider range of chemicals. 2. Operating temperature: The normal operating temperature range for PVC-U is relatively low, usually between 0 and 60 degrees Celsius. PVC-C has better heat resistance, with an operating temperature that can reach above 85 degrees Celsius. 3. Weather resistance: PVC-C has better weather resistance than PVC-U, making it more suitable for outdoor use. 4. Strength and stiffness: PVC-U performs well in terms of strength and stiffness, but PVC-C offers better strength and stiffness in high-temperature environments. 5. Price: The production cost of PVC-C is higher, so its price is usually higher than that of PVC-U. .
