Why Do Buyers Choose CPVC Pipe & Fittings First?

Choose CPVC Pipe & Fitting First

When considering piping options for either residential or commercial applications, the selection of material plays a crucial role. Among the many pipping material choices, the superior strength, performance and safety of Chlorinated Polyvinyl Chloride (CPVC) outranks the other and makes the ideal choice for process water applications and plumbing systems. It is a thermoplastic material which is often recommended because they have the ability to withstand high temperatures. CPVC pipes are used for both hot and cold-water passage industrial systems and are excellent in durability and flexibility. Earlier, metal pipes such as steel and other alloys were used for industrial piping and plumbing systems. However, the best CPVC pipes outperform the metallic piping systems and are more cost-effective over a longer period. With less maintenance, improved heat resistance, safety concerns, overall low installation cost and strong performance, CPVC pipes have gained popularity for many uses in the market. And offer uncountable benefits, that’s the reason many have largely relied on. The countries including Australia, Kenya and Ghana use CPVC pipes and fittings at an approximate rate of 66%. 


Understand the Prime Applications of CPVC Pipes


The following are the key areas where CPVC pipes are used for: –  

  • Residential Applications –   Who doesn’t prefer one tap for cold and hot water? Well, CPVC piping systems make it easy, as they are compatible with both cold and hot water systems. The CPVC resin is significantly more flexible and can withstand higher temperatures than normal piping systems. CPVC is growing as a choice for residential plumbing as it is deemed safe for the transport and use of potable water – i.e., water that can be used for drinking, cooking, and bathing. The CPVC pipes assure a safe supply of both hot and cold water.   
  • Commercial Applications CPVC plumbing pipes are used in various commercial buildings where low maintenance is required.  
  • Hospitals & Hotels The CPVC pipes are used to ensure a continuous round-the-clock supply of hot and cold water.  
  • Industrial Units Industries prefer CPVC plumbing pipes because of their many beneficial characteristics. For example, these pipes have high impact resistance and can bear a lot of pressure without cracking or sustaining damage. Additionally, the softening temperature is also lowered, making the pipes less likely to sustain damage during handling, storage, and installation – which makes them ideal for industrial applications. Furthermore, CPVC pipes are used in chemical plants, including the transportation of hot corrosive liquids and inorganic acids. 
  • Heating systems – They are ideal for radiant heating, central heating and solar heating applications.

CPVC Pipes for Hot Water Systems


The hot water piping systems can lead to damage to appliances, pipes and users due to overheating. If the temperature is not regulated, it can cause serious harm and injuries. Therefore, CPVC pipes are preferably used for hot water systems over metal pipes. This shift happened to overcome the inherent issues such as corrosion, leakages and scale buildup, which occurs in metal pipes.   

CPVC is known as Chlorinated Polyvinyl Chloride, which is produced by chlorination of Polyvinyl Chloride (PVC) resin. However, CPVC is extra chlorinated (approx. 67% chlorine) as compared to PVC, which gives additional quality features, including durability and higher operating temperatures. Generally, the best CPVC pipes can be used up to 200-degree Fahrenheit or 93 degrees Celsius.   

PVC pipes are used for plumbing and are very commonly used for irrigation piping, residential, commercial, pool and spa systems as well. One of the main issues with PVC pipes is that they are not the best option to use for hot water lines because they contain 57% chlorine. PVC pipes are more commonly used for cold water distribution because when they are heated up, they begin to break down and degrade. Additionally, PVC pipes will warp and bulge when exposed to hot water, which ultimately causes them to fail. For this reason, they are not suitable for transporting hot water to sinks, bathtubs and washing machines.  

The maximum operating temperature of PVC pipes is 140-degree Fahrenheit or 60 degrees Celsius. Any temperature above this will break down and either start leaking or burst. That’s the reason PVC pipes are recommended for cold water piping applications or applications where the water temperature doesn’t exceed 140-degree Fahrenheit or 60 degrees Celsius. Hence, PVC pipes and fittings are not the best or recommended plastic pipes for hot water applications and systems. That’s why the operating temperatures of CPVC pipes make them ideal for hot and cold-water systems and are widely used in industrial, residential and commercial applications.
