What is CPVC pipe?
CPVC is a thermoplastic made via chlorination of the polyvinyl chloride resin. This means its chemical composition is two carbon atoms double bonded to each other, with two hydrogen atoms and two chlorine atoms single bonded to the carbon. This molecule links with others to form chains of CPVC. It is resistant to degradation and provides a long service lifespan. In fact, the first piping systems using CPVC occurred in 1959, and they are still working without a problem.
CPVC pipe physical appearance
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). Pipes using the NPS system are light gray, and pipes using CTS system are yellow. Both types of pipe will have their specifications printed on the side.
CPVC and PVC similarities
It is safe to use CPVC in applications where PVC may be used. Both PVC and CPVC have been deemed safe for potable water transport, i.e. cooking, drinking, and bathing water, and they`re resistant to degradation from acid, alkali, and most inorganic chemicals7. However, both materials require UV stabilizers or burial to prevent deterioration from the sun.
They`re both a quieter, easier to install, and less expensive alternative to copper and iron pipes, especially in plumbing applications. Because they are thermoplastics, they have an inherent insulation that reduces condensation formation on the pipes, and maintains water temperature (both cold and hot) better than copper pipes do.
They are available in the same lengths, with the same end shape options. Because their chemical composition contains a halogen- the element chlorine- their structure is stable and innately fire retardant. This stability also inhibits oxidation, giving both a long, useful performance life. Each material can be identified by pipe color and by reading the printing on the pipe.
With mature formulation and advanced compounding technology ,we use own CPVC Resin and selected strictly additives to make CPVC Compound. CPVC pipes and fittings produced by our CPVC compound are most advanced for hot and cold water , Industrial and Fire pipeline system giving numerous advantages like corrosion resistance, chemical resistance, fire resistance, low thermal expansion, safety for drinking water, freedom from leakages and wall dampening, lowest bacterial growth besides easy installation and cost effective.- Novista
