The go-to pipe over the past 15 years has been standard PVC piping, but with research being conducted more and more, municipalities are switching to CPVC. Chlorinated polyvinyl chloride, or more commonly known as CPVC, is a thermoplastic pipe material. This form of pipe has been nationally accepted by plumbers since 1982, CPVC pipe has many benefits when compared with other plumbing materials. Generally, CPVC is used for supplying hot and cold potable water and in many other 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 nontoxic, while PVC may leech toxins into water at increased temperatures. CPVC also offers greater strength and flexibility, while PVC is far less ductile and could potentially crack and break under different types of stress. 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 and saving on labor costs. The thermal conductivity of copper pipe is 2,500 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 buildup. 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.
There are many different companies that distribute CPVC piping. To learn more about this product and the companies that distribute it, please visit the waterworld website at http://www.waterworld.com/articles/print/products/2013/april/cpvc-piping.html .
