When it comes to purchasing CPVC vs. PVC, you can distinguish the two by their colors. for? uPVC is used as a replacement for wood in construction, such as in double glazed window frames and window sills and in what is known as vinyl siding in the U.S. 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. It is also known as PVC’s cousin as they possess many similar properties.It is produced through a chlorination process of PVC resin. When PVC discolors under heat, it is burning and all work should cease immediately and be modified to prevent excessive toxins from becoming airborne. This individual molecule unit (a monomer) is then further linked together with other molecules of the exact same structure to form chains (a polymer) that are extruded as PVC to form PVC products like pipe. Before PEX came around, PVC (Polyvinyl Chloride) and CPVC (Chlorinated Polyvinyl Chloride) were the primary plastics used in plumbing. Often, pipes using the NPS system are light gray, and pipes using CTS system are yellow. Main Difference – PVC vs Polycarbonate. 2" pipe has a bend radius of about 4 feet and 1/2" pipe has a bend radius of about 2 1/2 feet. In fact, the first pipeline systems used by the CPVC occurred in 1959, and they continue to work without any problems. Each material can often be identified by pipe color and, if not, by reading the manufacturer printing located on the side of the pipe. For applications requiring temperatures above that, CPVC (chlorinated polyvinyl chloride) is recommended. CPVC pipe is non‐toxic.

Is there something else you are looking for? PVC can be cut with saws and glued to other PVC pipes and fittings without the need for heat or flame, such as is necessary to weld copper or iron pipes. Because their chemical composition contains a halogen -- the element chlorine -- their structure is stable and innately fire retardant. CPVC stands for chlorinated polyvinyl chloride. In PVC, a chlorine atom occupies 25 percent of the bonding sites on the carbon backbone, and the remaining sites are filled by hydrogen. All However, both materials require UV stabilizers or underground installation to prevent deterioration from the sun. Another thing we'd like to mention is that 2" pipe can be coiled up in less than a 3' diameter (1 1/2' radius) but if one bends it that much near a fitting that fitting will probably not be as strong. PVC is a thermoplastic polymer, while CPVC is a thermoplastic produced by the chlorination of PVC resin. Both come in Schedule 40 and Schedule 80 thickness. Because they are thermoplastics, they have an inherent insulation that reduces condensation formation on the pipes and maintains both cold and hot water temperature better than copper pipes do. CPVC pipes can also be utilized in the various applications where PVC pipes are usually used. For some applications you may determine a need to heat the pipe to make it more pliable -- be sure to wear protective gloves, respirator, and safety glasses to prevent burns and exposure to fumes. There are 15 material properties with values for both materials. 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.
