Faqs of CPVC Pipes
Chlorinated polyvinyl chloride (CPVC) is a thermoplastic pipe material. Nationally accepted since 1982, CPVC pipe has many benefits when compared with other plumbing materials. It is primarily used for supplying hot and cold potable water, and in industrial liquid applications.
CPVC pipe has a number of features that make it an improvement over standard PVC piping. It offers greater heat resistance, withstanding corrosive water temperatures between 70°F and 90°F higher than PVC. CPVC is non-toxic, while PVC may leech toxins into water at increased temperatures. CPVC also offers greater strength and flexibility, while PVC is far less ductile.
CPVC pipe has become a modern standard for water supply and liquid lines because of its cost saving benefits over metal piping. It is less expensive than copper piping and materials, as well as being lighter, making it faster and easier to install, saving on labor costs. The thermal conductivity of copper pipe is 2500 times greater than CPVC pipe, meaning it provides significant energy savings while keeping water hotter longer.
CPVC pipe is immune to galvanic corrosion and resists scale build up. It is also resistant to chemicals, and durable against their residues. Being plastic, it is not subject to electrolysis, the process in which water breaks down into oxygen and hydrogen gas. Installation is safer and faster, requiring only a special solvent cement, as opposed to a torch and solder for metal piping. CPVC piping generally lasts longer, as it is less susceptible to failures.
CPVC piping systems have been installed and operated since 1959, and initial installations are still performing faultlessly. CPVC piping will not fail prematurely due to corrosion, electrolysis, or scale build-up in areas where water, soil, and/or atmospheric conditions are aggressive.
