CPVC pipes are the best choice for the supply of drinking water.
You must be thinking, why?
Well, CPVC stands for chlorinated polyvinyl chloride, and it is a thermoplastic substance. PVC resin, often known as polyvinyl chloride or PVC, is manufactured using a chlorination process.
What are CPVC pipes?
They’re commonly used to deliver hot and cold water, as well as heavy industrial substances. The material is safe for drinking water applications because it does not react to most chemicals.
The most significant benefit of CPVC is that it is extremely flexible and can withstand high temperatures.
CPVC is a strong thermoplastic polymer. It is used in residential constructions for hot and cold potable water applications. One advantage of CPVC is that it is repellent to damage from chlorinated domestic water supply and has a high-temperature tolerance as compared to PVC due to its composition structure.
Merits of CPVC Pipes for Drinking Purposes
Flexibility and durability – CPVC pipes have a life lifetime of up to 75 to 80 years and require very little or no maintenance.
Mechanical strength – CPVC has a higher mechanical strength than PPR, making it a more durable and long-lasting material. Because of its great strength, CPVC can sustain high water pressure, even at extreme temperatures like those seen in industrial plants.
Chemically resistant – As CPVC pipes contain chlorine and go through a chlorination process, they are resistant to the dangerous hydrochloric acid. As a result, these pipes are chlorine resistant, safe, and long-lasting. CPVC pipes have several drawbacks too.
Demerits of CPVC Pipe Fittings
CPVC has the drawbacks of being brittle and not being able to tolerate extremely high temperatures like copper. The high thermal expansion coefficient of CPVC is another problem. As a result, CPVC may not be the best solution for areas with many temperature fluctuations. Furthermore, CPVC is often twice as expensive as normal PVC.
Applications of CPVC Pipes
It can be used for supplying drinking water to:
- Residential buildings — for use in both hot and cold water systems, both indoors and out.
- For low-maintenance water supply piping systems in commercial buildings.
- Hospitals and hotels – To ensure a constant and uninterrupted supply of hot and cold water around the clock.
- Industrial units — for use in chemical industries, including sprinkler fire suppression systems.
When buying CPVC pipes for drinking water supply, which brand should I go with?
CPVC pipes made by Vectus are extremely popular. You can also look at their product line and features on their website. You can also reach out to their executives directly over Whatsapp to get answers to your questions.
Is there any difference between CPVC and PVC pipe applications?
The material’s unique molecular structure confers particular advantages to CPVC industrial plumbing. PVC homopolymer that has undergone a chlorination reaction is referred to as CPVC. A chlorine atom covers 25% of the binding sites on the carbon backbone of PVC, whereas hydrogen fills the remaining sites.
Let us understand this in detail. This will also answer why CPVC pipes are preferable more for drinking water supply.
A few minor distinctions exist between the two materials.
The copper tube sizing method is distinct from Nominal Pipe Size, and it is the same system that is used for copper tube pipe, as the name implies.
Be sure to know what you’ll be using CPVC for and what sizing system you’ll need before you buy it. CPVC is typically light yellowish, whereas schedule 80 CPVC is light grey.
PVC pipe and fittings are often white or dark grey. To be sure, look at the manufacturer’s printing on the pipe.
PVC and CPVC require various primers and solvents for joining pipe and fitting joints due to their chemical makeup variances.
The ability of the cement to chemically soften the plastic is critical to the formation of a strong joint. As a result, you should always use cement made specifically for the material you’re working with.
Why isn’t every CPVC good for drinking purposes?
Although CPVC has a long and proven history as an industrial piping material, not all CPVC industrial piping systems are created equal. While some of the benefits of CPVC are universal (lightweight, ease of installation, low heat conductivity), CPVC compounds are distinguished by the level of performance they provide.
Base resins with varied molecular weights and chlorine levels, as well as other additives, are used to make CPVC compounds. These additives can alter chemical resistance and long-term performance.
It’s realistic to suppose that two CPVC industrial pipes constructed from different compounds will perform differently, just as two various types of industrial metallic pipes will likely function differently. As a result, it’s critical to inquire with your industrial plumbing supplier about the types of tests that have been performed on that particular CPVC Fittings.
