Despite the crunch in the real estate industry these past few years, the demand for cost-effective, reliable and high-quality piping and plumbing systems have increased. This is especially true a decade or so ago, when the housing and commercial building sector experienced a boom. Today, if you are in the process of having your plumbing fixed, or if a new home or office construction is in the works, you will definitely require an excellent material to use for the piping system.

 

Two options that you have, include PVC and CPVC pipes. Is one better than the other? Let’s try to discover the answer to that by making a comparison of the two materials. Firstly, there are the classic and popularly-known PVC pipes. The name stands for Polyvinyl Chloride, and it is a type of thermoplastic polymer, which is considered as the third most widely-produced plastic in the world.

 

The good thing about using the classic PVC material for piping systems, is that they are not only cheap, but they are also durable and easy to assemble. If a plumber needs the pipe to go through curves or unusually shaped openings, PVC can be made softer, and more flexible, by adding plasticizers.

 

So what’s the difference between PVC and CPVC? The latter stands for Chlorinated Polyvinyl Chloride, which is a type of thermoplastic material produced by subjecting PVC resin to a chlorination process. CPVC pipes are typically used for hot and cold water pipes, as well as the liquid heating system in industrial establishments.

 

In terms of the benefits, CPVC pipes are most suitable for carrying drinking water. Due to its smooth internal surface, CPVC pipes can be used to carry water for long distances without worrying about pressure loss, pitting or scaling. This type of pipe is also energy efficient, as it performs excellently under tough conditions, and is very easy to handle and install.

 

Meanwhile, PVC pipes are resistant to fracturing, they are not harmed by acids, they offer better water quality, and can even be used for thermal resisting applications. Depending on your budget and preferences, you can use either PVC or CPVC pipes for your home or office plumbing needs ,but it is best to consult a professional who knows which one will suit your needs the best.

 

Summary:

1. PVC is a thermoplastic polymer, while CPVC is a thermoplastic produced by the chlorination of PVC resin.

 

2. PVC can be used for a wide number of applications, while CPVC is mostly used for hot and cold water pipes, as well as industrial liquid handling.

 

3. PVC is less ductile, while CPVC offers greater strength and flexibility.
