PVC vs UPVC vs CPVC: Which PVC Pipes are better for you?

The qualities and materials utilized in PVC, uPVC and CPVC pipes are significantly different. Yes PVC, uPVC, and CPVC are non-metallic pipes but they have various chemical compositions and are used in plumbing and other non-critical applications. So let’s see what are the major differences in these 3 materials and which one is the best to use amongst them. 

The following are some of the benefits of using plastic pipes:

  • – They are less expensive 
  • – They are corrosion-resistant and do not require painting
  • – It does not require any heat conservation insulation
  • – Plastic pipes are easy to install, use and maintain. 

– So let’s understand the basic difference between 3 of the most used plastic pipes. 


What is PVC?

PVC (polyvinyl chloride) is a thermoplastic made up of 57% chlorine (derived from industrial grade salt) and 43% carbon (derived primarily from oil/gas via ethylene). It is one of the most commonly used plastics on the planet. It’s frequently used to replace copper and aluminium pipes, although it’s not recommended for window frames.

  • – It’s a highly adaptable and versatile substance.
  • – When compared to UPVC, it is less durable.
  • – It’s impervious to oxidation, oil, and a variety of substances. It can also endure heat and sunlight.
  • – For unheated water, PVC is utilised. It’s more suited to cold water systems.
  • – PVC can be utilized for a variety of purposes, including pipes, recreational use/building, drainage systems, cable insulation, toys, and so on.
  • – It is cost-effective and accessible.
  • – It is a biodegradable material that has a low environmental impact.
  • – Unlike UPVC, just 1% of PVC is recyclable.


Limitations of PVC pipe

PVC can not manage a temperature of more than 140° Fahrenheit. If the application requires a temperature above that then it is better to use CPVC as the material.

The name is self-explanatory. Because both CPVC and uPVC contain PVC, the real comparison is between CPVC and uPVC at the end. Although some items are manufactured entirely of PVC and include no additional materials.

So, what exactly is the distinction between CPVC and uPVC? Let’s have a look.


What is CPVC?

The chlorination of PVC polymer produces Chlorinated Polyvinyl Chloride (CPVC). It gains several special features as a result of chlorination, such as elasticity and the capacity to tolerate severe temperatures. It has good chemical resistance, particularly to acids, alkalis, and salts, because of its chlorine concentration, and is thus suited for the chemical process industry.

The fundamental distinction between CPVC and PVC is the temperature range that each can sustain. PVC can withstand temperatures up to 140 degrees Fahrenheit, while CPVC can withstand temperatures up to 200 degrees Fahrenheit. Both CPVC and PVC will soften at those temperatures, increasing the chance of joints and pipes failing, and hence the plumbing system failing.

Because of the changes in chemical makeup, primers, solvent cement, and bonding agents are different for PVC and CPVC. CPVC solvent cement, for example, must fulfill ASTM F493 standards, while PVC solvent cement must meet ASTM D2564 standards. As a result, CPVC and PVC pipes and fittings, as well as their solvents and bonding agents, should never be mixed. In addition to adhering to ASTM standards, depending on the pipe’s size and intended application, different solvent cement are necessary, so double-check the product containers to ensure you’re using the right agent for the job.

Here are some common uses of CPVC and PVC. 



  • – Underground Wire Housing 
  • – Infrastructure for plumbing, drainage, and sewage
  • – Delivery and distribution of drinking and processed water
  • – Ventilation, fume, and exhaust ducts
  • – Systems for agriculture, livestock, and agricultural irrigation



  • – Sprinkler and irrigation systems for the home
  • – Ventilation duct in the house
  • – Distribution of drinking water
  • – Infrastructure for residential plumbing, drainage, and sewage



  • – Shaded sitting places and makeshift tents
  • – Greenhouse, carport, and raised garden bed frames
  • – Crafts & DIY projects



In applications where PVC is used, CPVC is safe to use. Both PVC and CPVC have been recognised safe for transporting potable water, such as for cooking, drinking, and bathing, but only ANSI / NSF 61 certified plumbing should be utilized. Both CPVC and PVC have a high chemical resistance and can withstand acid, alkali, and most inorganic compounds without degrading. Both materials, however, require UV stabilizers or underground installation to prevent sun damage.


What is uPVC?

Unplasticized Polyvinyl Chloride (UPVC) is unplasticized PVC that has been stripped of its plasticizer, making it hard. It’s also chemically resistant to a wide range of substances. UPVC is a durable, sinewy, translucent, and long-lasting material that is resistant to the elements, moisture, and a variety of chemicals. It also has good electrical qualities and isn’t very flammable.

Pipes and fittings made of UPVC are widely utilized around the world. These pipes are more stiff and less flexible. The durability, fire resistance, and recyclability of UPVC pipes are all well-known.


Some of the most prevalent characteristics of uPVC

– Durable and cost-effective

– Rigid 

– Smoother inner surface 

– Reusable 

– Ideal for door and window frames 

– Environmental friendly 

– Low-maintenance


Final Verdict 

Because each of these materials is designed for a certain product or application, it’s best to use the right one for the job. Using uPVC for a product that should be made of PVC or CPVC can only cause you problems in the long term. So conducting thorough study and then selecting a specific material for a certain product is a better approach.
