Article Introduction
CPVC pipe is made from Chlorinated Polyvinyl Chloride compound, which is made from PVC resin. The CPVC resin is obtained by chlorination of PVC, to obtain a more stable polymer and overcome the limitations of PVC in terms of temperature resistance. The vicat softening temperature of CPVC Pipes is more than 110°C & the heat distortion temperature is in the range of 100-110°C, making it an ideal choice for both hot and cold water.
Through the following article content, you can have a deeper understanding of CPVC pipes !
The Effects of Hot Water on Water Piping
Many plastic piping systems can withstand cold water at high pressures. However, as the temperature of water rises, plastic materials start losing their rigidity and the pressure bearing capabilities reduce (based on the type of plastic used.
In the case of CPVC, due to its inherent stable molecular structure, the pressure bearing capacity at elevated water temperatures is high and hence the pipes are suitable for use in hot water, at high pressures.
The dissolved chlorine in water becomes very aggressive, especially in hot water, attacking metal and corroding it rapidly. Plastics like PPR and PE are vulnerable to hot chlorinated water and it has been seen that the rate of erosion of the wall of these pipes is very high, making them weak and leading to leakages.
How Long Does CPVC PIPE Last ?
CPVC compounds used for manufacturing pipes were invented by Lubrizol. Lubrizol supplies CPVC raw materials to manufacturers under a licensee agreement. Pipes made from Lubrizol CPVC material are designed for a service life of 50 years for hot & Cold water applications, and are recommended for a maximum temperature of 93°C.
SAM-UK CPVC piping systems are tested at various pressures and temperatures and have been in use for over 65 years since its inception. CPVC pipe can be used for continuous operating water temperature of 93°C and pressure of 7.5-8Kg/cm2,.
Recommended maximum allowable operating temperatures for other plastics are:
PPR pipe – 70°C for 50 years
PPH pipe – 20- 90°C for 50 years
PVC pipe – 35-40°C for 50 years
Water heaters are generally preset to deliver a maximum of 60°C. CPVC Pipe therefore offers a major safety factor, in case of water heater malfunction, compared to other plastic pipes.
Summarize
SAM-UK CPVC plumbing pipes are a reliable choice for residential plumbing applications. Due to its resistance to chlorine, corrosion,heat distortion, temperatures well above normal potable water levels, as well as increased pressure bearing capability, it is ideal for use in hot and cold water lines in homes in China and across the globe.
