PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) flanges are essential components in piping systems, known for their durability, corrosion resistance, and affordability. These flanges provide secure connections between pipes, valves, and equipment in various applications, including water supply, chemical processing, and irrigation. PVC flanges are suitable for non-pressure and low-pressure systems, while CPVC flanges are ideal for higher temperature and pressure applications.
