PVC stands for polyvinyl chloride, and it’s ended up being a typical replacement for metal piping. PVC’s strength, durability, simple installation, and low cost have made it one of the most utilized plastics worldwide. PVC is a thermoplastic material that is formed into various shapes to produce pipes, fittings, valves and other liquid handling materials.

So Just What is CPVC?
You can think of CPVC as PVC’s cousin. They are similar in many methods, but they should not be utilized interchangeably. Both are made of the same standard aspects with one distinguishing element. CPVC is changed by a totally free radical chlorination reaction that efficiently increases the chlorine content of the material. CPVC is likewise a thermoplastic that is molded into many of the very same items as PVC.
This difference in makeup permits CPVC to hold up against a wider range of temperatures. This is why lots of building regulations require making use of CPVC as opposed to PVC for use in hot water applications. The ASTM standard enables PVC to be used in applications not going beyond 140 degrees F.
Temperatures over this can cause softening of the product and weakening of joints. CPVC on the other hand can deal with temperature levels approximately 200 degrees F.
