Some differences between PVC and CPVC pipes


 PVC pipes are flexible plastic pipes used for drainage and piping. Metal pipes have been replaced as a common material by PVC pipes. Due to its strength, longevity, simplicity of installation, and low price, PVC is the most commonly used plastic in the world. CPVC is different from PVC because of a process done to it by a cpvc pipe manufacturer called free radical chlorination. This raises the amount of chlorine in the pipe. PVC and CPVC are both thermoplastics that are used to make a variety of items.

Here are some of the differences between PVC and CPVC:

Deciding between PVC or CPVC

Both PVC and CPVC are authorized for the transportation of potable water, which is used for drinking, cooking, and bathing. Both CPVC and PVC have high chemical resistance and are virtually unaffected by most organic compounds, acids, or alkalis. Buy CPVC pipes with UV stabilizers applied on them by the cpvc pipe manufacturer to stop degradation from the sun. Or you can install the pipes underground for sun protection.

Here are some of the differences between PVC and CPVC:

Temperature tolerance difference

PVC can tolerate only temperatures of up to 140 degrees F. The PVC will melt at temperatures over 140 degrees. To give you an idea, a hot water heater's maximum temperature is often between 120 and 140 degrees Fahrenheit. CPVC can tolerate a maximum of 200 degrees Fahrenheit, which is 60 degrees more than PVC’s temperature tolerance. 

The cpvc pipe manufacturer adds chlorine to CPVC to strengthen its resistance to heat. This addition also alters its strength. Both PVC and CPVC are robust, but CPVC is tougher. CPVC is more adaptable and flexible than other pipes. If the CPVC tube is long, you can support it every three feet.

Cost difference 

Because chlorine is added by cpvc pipe manufacturer during the manufacturing process, the cost of CVPC pipes differs from PVC. PVC and CPVC are significantly less expensive than metal or PEX pipes. Depending on the manufacturer, a PVC or CPVC's exact cost and quality will change. Although CPVC will always be more heat resistant than PVC, temperatures exceeding 200 degrees Fahrenheit may cause it to malfunction. CPVC is often used for hot water applications due to its high cost, whereas PVC is used for cold water applications like irrigation and drainage.

Final thoughts

Because of the materials that make up CPVC, it can tolerate a variety of temperatures. Because of this, several building rules specify that CPVC should be used in hot water applications rather than PVC. Due to its makeup, CPVC is more temperature-tolerant than PVC and can withstand the impacts of excessively chlorinated water.

Why use HDPE Pipes for industrial uses?

Image
  Agricultural and lift irrigation, submarine pipelines, desalination facilities, industrial water transportation, coal handling, chemical lines, and HDPE pipes are just some of the many industrial uses for these pipes. The popularity of HDPE pipe manufacturers in India is due to its high tensile strength, durability, and lightweight properties. To help you understand the advantages of HDPE pipes for industrial use, we've compiled a list of reasons why: Resistance to corrosion  Metal pipes have a long history of industrial usage because of their high corrosion resistance. It was, however, a bad option due to corrosion. Water and low-temperature liquids may be transported more efficiently using HDPE pipes than through metal pipes. A variety of industrial applications in chemical and geothermal facilities may benefit from its corrosion-resistant qualities. Chemical resistance  HDPE pipes are increasingly replacing carbon steel pipes in several sectors because of their supe...

Benefits of using SWR pipes

Image
  You may be aware that, in the modern world, complex sewerage systems are essential. The introduction of plastic pipes such as PVC and uPVC pipes has become much easier and more cost-effective to keep your home and the entire world clean and hygienic using scientifically designed drainage systems. So, it is important to use in the sewage system. You can use a SWR PVC pipes because it is more beneficial for soil, waste, and rainwater management. SWR stands for Soil, Waste, and Rain. These pipes are resistant to bacteria, fungus, germs, rodents, and insects. SWR pipe manufacturer joins in various forms and sizes, depending on the pipe size, for merging, redirecting, and lowering water supply flow. Below listed are all the benefits of using SWR pipe: Easy installation and maintenance Are SWR pipes easy to install? Due to its lightweight, SWR pipes are less likely to hurt and injure installers during installation. As a result, installing  SWR PVC pipes  requires le...
