The range of temperatures that each material can sustain is the primary distinction between CPVC and PVC. PVC peaks at 140° Fahrenheit whereas CPVC can withstand temperatures of up to 200° Fahrenheit. Both CPVC and PVC will start to soften at certain levels, increasing the possibility of joints and pipes collapsing and, consequently, the entire system failing.
PVC is only available in nominal pipe sizes, however CPVC is also offered in copper tube sizes. Since CPVC is more flexible than PVC, it needs support every three feet to stay in place.
COMPARED CPVC AND PVC
In situations where PVC may be used, CPVC can be utilized without risk. Both PVC and CPVC have been approved for the transportation of potable water, which includes water for cooking, drinking, and bathing. However, only plumbing that has been certified by ANSI / NSF 61 should be utilized. Both CPVC and PVC have high chemical resistance and are mostly unaffected by acid, alkali, and the majority of inorganic compounds. To stop degradation from the sun, both materials need UV stabilizers or subterranean installation.
Particularly for plumbing purposes, CPVC and PVC are both cheaper, easier to install, and quieter options to copper and iron pipes. The fact that they are thermoplastics gives them a built-in insulation that prevents condensation from forming on the pipes and maintains the temperature of the cold and hot water more effectively than copper pipes do.
They come in the same lengths and with the same options for end shapes. Because chlorine, a halogen, is a part of their chemical makeup, their structure is stable and naturally fire resistant. In addition to preventing oxidation processes, its stability gives PVC and CPVC extended, beneficial performance lives. Each material may frequently be distinguished by the color of the pipe, and if not, by reading the manufacturer's printing on the pipe's side.
Visual similarities and differences between CPVC and PVC
PVC pipes come in two colors: white and dark gray.
Off-white, light gray, or yellow are the colors of CPVC.
Technical details for both pipe types are provided on the side for simple verification.
Both plain end and bell end pipes are offered.
Schedule 40 and Schedule 80 thicknesses are available for each.
Also available in Class 125 fittings is Schedule 40 PVC.
PVC comes in lengths of 10 and 20 feet.
The lengths of CPVC are 10 and 20 feet.
PVC pipe in certain diameters and furniture PVC pipe are now offered in 5 foot portions.
PROPERTIES OF CPVC AND PVC
Both are resistant to corrosion and deterioration from substances that are classed as acidic, alkaline, or made of inorganic materials.
The highest functional temperature for PVC is 140 °F.
The highest functional temperature for CPVC is 200 °F.
The additional chlorine in CPVC boosts chemical resistance and aids in preventing the growth of germs and biofilm inside the pipes.
Both have durability and impact resistance.
When they are both ANSI/NSF 61 approved, both are safe to use with potable water.
