CPVC or chlorinated polyvinyl chloride is a thermoplastic polymer. For more on what PVC and PVC pipe is used for, read our resource article What is PVC Used For. A. CPVC maximum functional temperature is 200° Fahrenheit. Because their chemical composition contains a halogen -- the element chlorine -- their structure is stable and innately fire retardant. CPVC pipes are sized in two ways -- nominal pipe size (NPS references the diameter of the interior hole of the pipe) and copper tube size (CTS references the outside diameter of the tube). Commonly used to create plumbing pipes and fittings, For more on what is PVC, the characteristics and properties of the plastic, read our resource article, The color of PVC pipe is traditionally white or dark gray, with a technical description of the pipe printed on the side. CPVC is a more expensive product so it is usually the chosen material for hot water applications, while PVC is used for cold water applications like irrigation and drainage. While both PVC and CPVC are suitable for water, gas, and drainage systems, many plumbers strongly recommend CPVC for hot water lines and PVC for cold water lines. For applications requiring temperatures above that, CPVC (chlorinated polyvinyl chloride) is recommended. but only plumbing that has received ANSI / NSF 61 certification should be used. CPVC, PEX and PVC pipes and components fail from time to time. As a flexible plastic, PVC is used to produce a wide variety of piping. CPVC is a PVC homopolymer that has been subjected to a chlorination reaction. For example, CPVC solvent cements must meet ASTM F493 specifications, and PVC solvent cements must meet, Plumbing, drainage, and sewage infrastructure, Drinking and process water delivery and distribution, Agriculture, livestock and farm irrigation systems, Residential plumbing, drainage, sewage infrastructure, Frames for greenhouses, carports, and raised garden beds, For more on what PVC and PVC pipe is used for, read our resource article. CPVC is available in 10 ft and 20 ft lengths. PVC stands for polyvinyl chloride; CPVC stands for chlorinated polyvinyl chloride; and PEX stands for cross-link polyethylene. It is resistant to degradation and provides a long life span of use. Pros. CPVC pipe and fittings are cream colored, while PVC pipe and fittings are white. While the name sounds redundant, it describes the process of increasing the chlorine content in PVC. Both come in Schedule 40 and Schedule 80 thickness. When PVC or CPVC is heated, melted, or hot-cut, fumes that are toxic (. Looking for PVC pipe for sale or to compare prices? PVC is the common term for Polyvinyl Chloride. Commercial CPVC usually has 63 to 69 percent chlorine content, but is capable of containing as much as 74 percent. Both forms of PVC are safe to touch and handle, and do not leach chemicals when used as the manufacturer intended. It is safe to use CPVC in applications where PVC may be used. © 2021 PVC Pipe Supplies. It is hard to believe that they are not completely resistant to UV rays. CPVC and PVC are both a quieter, easier to install, and less expensive alternative to copper and iron pipes, especially in plumbing applications. PVC pipes are sized by the nominal pipe size (, CVPC pipes are sized by the nominal pipe size (. cooking, drinking, and bathing water, but only plumbing that has received ANSI / NSF 61 certification should be used. The Premier Online Plumbing Supplier Since 1995, Same day shipping for in-stock orders processed by 7pm EST M-F. OR - find plumbing supplies starting with: While CPVC can technically do anything PVC can, its use in the home is usually limited to. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing, and therefore, failing of the plumbing system. CPVC and PVC pipes are made out of very strong and versatile materials. When working with PVC or CPVC, work in a well-ventilated area with proper safety apparel, including gloves, goggles and a respirator if available. For example, ¾” Sch40 PVC pipe is rated at an extremely high pressure of 480 psi at 73 degrees, but it has no high-temperature rating whatsoever. The primers, solvent cements, and bonding agents are different for PVC and CPVC due to the differences in the material's chemical composition.
