(CPVC pipes and PVC pipes)
The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing.
The primers, solvent cements, and bonding agents are different for PVC and CPVC due to the differences in their chemical composition. For example, CPVC solvent cements must meet ASTM F493 specifications, and PVC solvent cements must meet ASTM D2564 specifications.
Because of this, CPVC and PVC pipes and fittings, along with their solvents and bonding agents, should not be used interchangeably. In addition to meeting ASTM specifications, there are different solvent cements required based on the pipe`s size and intended application, so check the product containers to be sure you`re using the correct agent for the correct application.
PVC comes in nominal pipe sizes only, while CPVC is available in both nominal pipe sizes and copper tube sizes. CPVC has greater flexibility than PVC, and requires support at three foot intervals to maintain its position.
CPVC and PVC visual differences:
--PVC pipes are white or dark gray in color.
--CPVC is off-white, light gray, or yellow.
--Both pipe types have technical specifications printed on the side for easy verification.
--Both pipe types are available in plain end and bell end.
--Both come in Schedule 40 and Schedule 80 thickness.
--PVC is available in 10 ft. and 20 ft. lengths.
--CPVC is available in 10 ft. lengths.
