Nijanand CPVC pipes are compatible with both hot and cold water. It can withstand very high temperatures upto 93℃. Many solar, elctric and gas water heaters have CPVC piping system for heat efficiency and lower installation cost.
Even after years of use in the most aggressive conditions, this pipe won't corrode, standing against low pH water, coastal salt, air exposures and corrosive soils. It stays as solid and reliable as the day it was installed, maintaining full water carrying capacity.
Bacteria build up with CPVC is far lower than with alternative piping materials due to very smooth internal surface. It does not deteriorate quality of water and prevents contamination, unpleasent odour, bad taste and discolouration of water.
Nijanand® CPVC pipes has a much higher strength than other thermoplastics used in plumbing.It needs less hangers and supports and there is no unsightly looping of the pipe. It has a higher pressure bearing capability.
CPVC plumbing system is approved for contact with potable water in wide range of countries including USA, UK, Canada, Germany, France, The Netherlands, Middle East, Africa etc.
CPVC has a Limiting Oxygen Index (LOI) of 60. Thus in air, Nijanand® CPVC pipes does not support combustion. No flaming drips, does not increase the fire load, low flame spread, low smoke generation.
Nijanand® CPVC pipes has a lower coefficient of thermal expansion, reducing the amount that the pipe expands when hot water is running, again reducing unsightly ‘looping’ of the pipe.
CPVC uses a simple, solvent cement jointing method. Tools required are very simple and inexpensive (chamfering tool and pipe cutter only) and avoid the need for an electrical source.
Some materials may be adversely affected by chlorine contained in the water supply, which can cause breakdown of the polymer chains and potential leaks. In this respect, Nijanand® CPVC PRO pipe is unaffected by the chlorine present in potable water supply.
Nijanand® CPVC pipes gives excellent resistance even under the harshest of water conditions so there are none of the purity worries from corrosion of metal pipe or soldered joints. Nijanand® CPVC pipes keeps pure water pure.
