CPVC as a Material for Pipes and Fittings

What are CPVC pipes and fittings?

CPVC (chlorinated polyvinyl chloride) is a robust, long-lasting polymer that has been utilised in plumbing applications for more than 50 years all over the world. CPVC is a thermoplastic created by chlorinating polyvinyl chloride resin further. This involves two carbon atoms linked together, two hydrogen atoms, and two chlorine atoms connected to this double carbon unit. This molecule joins together with others to produce CPVC polymer chains.

Characteristics of CPVC

● 200° Fahrenheit is the maximum functional temperature of CPVC.

● The additional chlorine in CPVC boosts chemical strength and prevents germs and biofilm from forming inside the pipes.

● CPVC pipes are generally grey, yellow or white.

● CPVC is chemically inert.

● It is available in sheets, rods, and tubes and has good fire resistance and chemical resistance.

Advantages of CPVC pipes and fittings

1) Resistance to chlorine

CPVC is inherently resistant to the effects of chlorine and chlorine dioxide, which are commonly used to disinfect drinking water. CPVC is protected by massive chlorine molecules rather than the hydrogen molecules surrounding the backbone of conventional polymers. As a result, extensive exposure to chlorinated water will have little to no effect on the pipe in corrosion.

2) Mechanical Strength

CPVC has a higher mechanical strength than PPR, making it a more robust and long-lasting material. Because of its great strength, CPVC can handle increased water pressure, even at severe temperatures like those seen in industrial facilities.

3) High heat tolerance

Another advantage of CPVC pipes is that they can tolerate high temperatures. This implies that this sort of pipe can convey both cold and hot water. CPVC pipes can resist temperatures as high as 200° Fahrenheit! This capability demonstrates how long-lasting CPVC pipes are. They're quite adaptable and may be utilised for a wide range of tasks.

CPVC pipes are manufactured using a composite polymer, and the manufacturing process of these pipes is extrusion which uses a double screw. Due to the manufacturing process, they acquire a constant diameter, and the material helps them gain abilities such as withstanding high temperatures and increased flexibility. In addition to this, it is highly thermally efficient, and therefore, it does not affect the physical properties irrespective of its temperature. Thus, the CPVC fitting and pipes are most suitable for hot and cold-water delivery systems. They are also known for transferring highly toxic fluids in industries. They can bear a significant amount of pressure without reinforcement of rimming or webbing within the walls of the pipe as well as it is resistive to impacts and therefore, it can be used as a long-term solution and is highly durable in comparison to the normal PVC pipe systems. It is completely safe to utilise CPVC to transfer potable water, and therefore it can be used for bathing, drinking, cooking and so on. The composite material is chemically neutral, and therefore it does not react with any other compounds it carries.

In summary, the CPVC pipes and fitting solutions can be utilised for the following:

● It can be used in the circulation of hot and cold water across households, commercial buildings, and industries.

● It can be used in the industry to circulate toxic or high-temperature liquids.

● The chemical properties of the composite are neutral and therefore does not undergo any chemical reactions with the fluid that it may carry

● It can withstand high pressure and is highly resistive to impact, and therefore can be used for the long run.

● It is very safe to use as a plumbing pipe, and it can even be used for domestic purposes such as drinking water, bathing, cooking etc.

The range of CPVC pipes and CPVC fittings varies between 15 mm and 100 mm and is available throughout the market as it is mass-produced. The pipes can be chosen depending upon the requirement, and some special sizes can also be ordered from manufactures that are not mass-produced.
