The difference between PVC-C fire special pipe and CPVC civil water supply pipe
PVC-C special fire-fighting pipe is the term used in the new national spray regulations, that is, chlorinated polyvinyl chloride pipe, which is specifically for fire-fighting special plastic pipe. GB 50084-2017 "Specifications for the design of automatic sprinkler systems" and GB 50261-2017 "Specifications for the construction and acceptance of automatic sprinkler systems" implemented on January 1, 2018 have all described and specified this.Chlorinated Polyvinyl Chloride (PVC-C) pipes and fittings can be connected with adhesives, and other materials can be connected with threads, flanges or grooved connectors (clamps). Before this, the common name in the industry was CPVC, and the common ones were power pipes and water supply pipes.
PVC-C and CPVC are essentially the same, they are both chlorinated polyvinyl chloride, but because of the characteristics of the fire sprinkler system, they require high pressure and special combustion resistance, and their raw material formulations and pressure ratings are higher than For ordinary CPVC, the cost and market price will be higher.
