What are PVC Pipes?
Plumbing pipes and fittings are usually created using PVC, PVC (Polyvinyl Chloride) is an artificial plastic that has added stabilizers to prevent oxidation and degradation. PVC products and pipe-work are highly durable as it is engineered to resist degradation. When properly installed, these products can have a lifespan of up to 50 years or in some cases, they can last even longer. Poorly glued joints or tree roots displacing underground lines or burrowing their way into the pipe itself are some of the very few reasons why PVC pipes can fail.
Physical characteristics of PVC pipes
Traditionally the PVC pipes are in white or dark grey colour. On the side of the pipe, its technical description is printed. PVC can be found in both rigid and flexible forms. The rigid form is called uPVC and is usually used in construction and piping applications. The flexible form is just simply called PVC and is often used as insulation on electrical wiring. Both rigid and flexible forms of PVC are safe to touch and handle, they do not teach chemicals as long as they are used as the manufacturer intended.
What are CPVC Pipes?
CPVC pipes are made of thermoplastics that are created by further chlorination of the polyvinyl chloride resin. Two carbon atoms bonded to each other with two hydrogen atoms and two chlorine atoms bonded to this double carbon unit make up its composition. This molecule forms chains by linking with other molecules to make CPVC. Like PVC, CPVC also delivers superior resistance to degradation and provides a long service lifespan.
Physical characteristics of CPVC pipes
There are two sizes of CPVC pipes available- Nominal Pipe Size (NPS), which references the diameter of the inner hole of the pipe, and Copper Tube Size (CTS), which refers to the outer diameter of the pipe. Usually, pipes of the NPS system are coloured light grey, and pipes that use the CTS system are coloured yellow. Both types of pipes have their specifications printed on the side.
Differences between PVC and CPVC Pipes:
• PVC Pipes are white or dark grey in colour.
• CPVC Pipes are light grey or yellow in colour.
• The maximum functional temperature for PVC Pipes is 140 degrees Fahrenheit.
• The maximum functional temperature for CPVC Pipes is 200 degrees Fahrenheit.
• CPVC Pipes contain extra chlorine which increases chemical strength and helps prevent bacteria /biofilm formation within the pipes.
• PVC Pipes are more budget-friendly.
• CPVC Pipes are comparatively more expensive than PVC Pipes.
• PVC Pipes are most suitable for recreational applications, residential construction, DIY projects and cold water distribution.
• CPVC Pipes are most suitable for commercial applications, chemical handling and hot water distribution. Choosing the right type of pipe is very important as it makes sure that the task is carried out without any complications. The quality of the pipe is also just as important, Kasta pipes the largest manufacturers of CPVC pipes in India and also manufactures the best quality PVC Pipes in India. provide their customers with the highest quality of pipes to meet everyone’s needs.
