Understanding The Differences Between Pvc and Cpvc Pipes and Fittings

Among the most common thermoplastics used for water supply and management systems, polyvinyl chloride and its modification, chlorinated polyvinyl chloride, PVC and CPVC respectively are among the most popular choices around the world. Both pipe materials offer a whole range of benefits in terms if usage, especially higher corrosion resistance, ease of installation, durability and others. However, even though these pipe materials are from the same category, there are significant differences between them. Let us understand the differences between CPVC and PVC:
1. Differences in chemical composition: The most obvious difference between PVC and CPVC pipes and fittings is that of their chemical composition. CPVC is a modification of PVC which is manufactured by the process of chlorination, which transforms the chemical composition and molecular structure of CPVC, thereby affecting its physical properties as well.

2. Differences in physical appearance: While it may not be obvious to the layman, CPVC and PVC are also different in physical appearance. PVC and CPVC pipe fittings and pipes often look similar on the outside and hence they are differentiated by the colour of the pipes. PVC pipes are traditionally available in white while CPVC is available in an off white colour.

3. Difference in temperature resistance: Another important difference between PVC and CPVC comes in terms of the operational temperature that they can withstand. PVC pipes are able to withstand a functional temperature of about 60 degree Celsius while the best CPVC pipe for hot water has a temperature resistance of about 93 degree Celsius over the long term, which also makes it suitable for installations in hot water connections across domestic, commercial, and industrial applications.

4. Differences in joining methods and materials: While both PVC and CPVC pipes and fittings are easy to install, they are both installed using different solvents and cements. For each of the materials, the primers, solvents and cements used for installation are different and cannot be used interchangeably. Similarly, it is advisable to not use the pipes and fittings of CPVC and PVC interchangeably to ensure leakproof connections.

The use of pipes for supply of water, other liquids, and gases is essential infrastructure for meeting the daily requirements of life. There are many different pipe materials which are used around the world for such functions and these include both metal and non-metal solutions, including plastic. While traditionally, metal pipes were in widespread use for water supply as well as other piping applications, these have given way to thermoplastic materials which have widespread benefits.

Advantages Of Best CPVC Pipe

 Given the corrosion resistance, durability and longevity of plastic pipes, they have become the most popular choice for plumbing and sanitation applications. Among the different thermoplastic pipes which are used in pipe networks, chlorinated polyvinyl chloride or CPVC pipes are one of the most ideal choices. Read on to know some of the various advantages of using CPVC pipes and fittings: The best CPVC pipe is extremely cost effective as compared to metal pipe systems and also requires much less maintenance. This reduces the long term costs of a CPVC pipe network significantly.  The pipes made from CPVC are resistant to most types of harsh chemicals, including several acids and bases, as well as to natural or environmental corrosion. This makes them suitable for high efficiency performance without damage. The smooth inner surface of the CPVC pipes ensures that any substance flowing through them does so at optimally high pressure. This bri...
