A Comprehensive Overview of CPVC Pipes & Fittings

Do you want to know about CPVC material fittings? Many DIYers are often confused about CPVC material for their pipes & plumbings. CPVC is a highly durable, chemical-resistant, and long-performing material. Read through this post to have a comprehensive overview of CPVC fittings.

CPVC stands for Chlorinated Polyvinyl Chloride. The manufacturers fabricate the PVC fittings for pipes using CPVC compounded material. Notably, it is one of the sturdiest and long-standing materials, extensively used in piping applications for more than 50 years.

CPVC capably resists even the most adversarial chemicals. Also, it can endure exposure to extreme temperature and pressure. Both these characteristics make it a suitable material for residential and commercial, and industrial piping applications.

What is CPVC?

PVC (Polyvinyl Chloride) is a man-made durable plastic that has various uses. While its fabrication, manufacturers add stabilisers to make it resistant to oxidation & deterioration. CPVC is similar to PVC, except for the fact that the process of manufacturing CPVC additionally chlorinates the plastic material. CPVC modifies its chemical composition which enables the CPVC pipe fittings to withstand degradation highly and facilitates it to last a long time.

The manufacturing process of CPVC makes it ideally useful in commercial and industrial fields that are likely to have the presence of chemicals and high temperatures.

Why Should You Use CPVC?

The chemical composition of CPVC pipes & fittings provides high corrosion resistance and helps in withstanding wear & tear over long usage. Also, in comparing the PVC, CPVC pipes and plumbings are better suited for high temperatures. The maximum working temperature of PVC is 140 degrees, while that of CPVC is up to 200 degrees (after which it may start softening).

The CPVC material is more flexible than the traditional metal pipes made of cast iron or copper. The CPVC are lightweight and easy to install.

Types of CPVC Pipes & Fittings

  • Plain Pipe Fittings: Plain pipe fittings are basic CPVC fittings, such as CPVC Elbow, CPVC T-fitting, CPVC Socket, & CPVC End cap, etc.
  • Threaded Pipe Fittings: Threaded pipe fittings are mechanical joints among male-female threaded fittings, such as CPVC MTA and CPVC FTA. A Teflon tape is used as a sealant for such fittings.
  • Transition Pipe Fittings: Transition pipe fittings are useful for joining pipe meetings. These include Brass Tee, Brass MTA, Brass FTA, and Brass Elbow.
  • Tank Nipple: Tank nipples are available as both end or one end thread. They are used to connect the overhead tank with the entire piping system.
  • Union: Union is a combination of a threaded adaptor, a plain adaptor, and a threaded ring. Its main function is to connect two pipes, similar to a socket, except for the dissimilar fact that a union can be easily removed at any time.
  • Valves: CPVC Valves regulate the flow of water & other fluids, with opening & closing functionality. The most common valves used in piping systems are the Ball valve & concealed valve.
  • Flange: A flange joint is useful for connecting pipes, valves, pumps & other plumbing equipment in a piping system. CPVC flanges offer great strength & are corrosion-resistant. These joints are made by bolting two flanges together with a sealing gasket between them.

Applications of CPVC Fittings

CPVC Fittings & Plumbings have wide usage in piping systems in different settings. These are extensively used in places like hospitals, hotels & resorts, academic institutes, industrial plants, residential structures & high-rise buildings, swimming pools, and more.

Here are a few notable applications of CPVC fittings:

  • Water Supply – The CPVC fittings are suitable for hot and cold distributing water in residential and industrial infrastructures. They can be safely used to supply potable water and food liquids. Also, they are useful in water treatment plants.
  • Chemical Transportation –  The CPVC plumbings & fittings are extensively used in industrial plumbing for the transportation of chemicals. They are useful for distributing aggressive chemicals or other hot corrosive fluids, including inorganic acids, bases, and other fluids used across the industrial plant for processing.
  • Fire Sprinkler – CPVC pipe fittings are also used for fire sprinkler applications that automatically discharge water when it detects any fire element.

Another good material that can be used for pipes and fittings is UPVC (Unplasticized Polyvinyl Chloride). It does not involve BPA or phthalates and is regarded as a safe product for the environment. Notably, UPVC fittings are also better than PVC, concerning high tensile strength & durability.

Conclusion

CPVC is superior to conventional PVC material. Though both of these are sturdy, flexible, and resistant to wear & tear, CPVC stands out in each of these features. Remarkably, apart from its extensive usage in commercial infrastructure and factories, CPVC is also useful for residential applications. CPVC pipes are a great medium of distribution for potable water, which makes them a feasible choice for residential plumbing applications as well.
