This material is used in domestic water supply, hot water systems, piped drinking water systems, commercial pure water systems, deionized water systems for the electronics industry, pure water systems for medical dialysis, and hot and cold water systems for air conditioning. In North America, PVC-C pipes have already achieved a certain market share in these areas. Furthermore, in the Indian market, CPVC pipes and fittings are primarily used in residential and real estate hot and cold water piping systems. In recent years, PVC-C has also been used in civil building water supply systems, especially hot water systems. PVC-C automatic sprinkler systems entered practical use in the United States in 1986. Blaze Master PVC-C automatic sprinkler pipes have obtained certifications from relevant fire protection agencies such as UL (Underwriters Laboratories), ULC (Underwriters Laboratories Canada), FM (Factory Mutual Insurance Institute), and LPC (Land of Property Loss Prevention).
PVC-C fire-fighting pipes possess characteristics such as ignition resistance, flame retardancy, and resistance to exposed combustion. The gases produced after combustion have low toxicity. Their smooth surface and low pressure loss make them resistant to microbial corrosion. Their installation process is relatively efficient, and they have strong pressure resistance, making them suitable for light-hazard and medium-hazard Class I buildings as defined in GB50084. However, it is important to note that PVC-C fire-fighting pipes are only suitable for wet-pipe automatic sprinkler systems and are strictly prohibited from being used to transport compressed air or other gases.
PVC-C hot and cold water pipes are made from seawater salt, making them environmentally friendly. The pipes have strong chlorine resistance, helping to maintain water quality. The pipe system is oxygen-impermeable, therefore it is not easily corroded by oxidation. It has good corrosion resistance and can withstand corrosion from various chemicals. It can withstand long-term high temperatures of 93℃ and low temperatures of -26℃. Hot water pipe systems can be buried in cement slabs.
Products from authorized manufacturers have passed the "type tests" of relevant fire protection research institutes.
Furthermore, CPVC pipes, due to their high strength, high temperature resistance, corrosion resistance, good insulation, and light weight, are used as electrical conduits, i.e., protective pipes for electrical wires and cables. Its performance has passed quality inspection and certification, making it a viable alternative to traditional steel pipes.
With the rise of Artificial Intelligence Data Centers (AIDCs), the requirements for high-temperature resistance, pressure resistance, insulation, and corrosion resistance in power transmission and cooling system pipes far exceed those of traditional applications. PVC-C piping systems, possessing excellent high-temperature resistance, insulation, and flame-retardant properties, are becoming an emerging application area suitable for critical supporting needs such as high-voltage cable laying in AIDCs.
