Difference between PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride):

PVC and CPVC

PVC pipes and PVC fittings are produced using polyvinyl chloride, a man-made plastic, regularly used to make with added stabilizers that forestall oxidation and corruption. These lines are otherwise called UPVC (unplasticized polyvinyl chloride) pipes.

CPVC plumbing pipes are produced using chlorinated polyvinyl chloride, a thermoplastic material that can endure higher temperatures and is more adaptable and sturdy. These lines are utilized for hot and cold water sections and other modern fluids.

Difference between PVC and CPVC:

Both PVC and CPVC are similar to each other, with some differences between them. The difference are listed below:

  • Life Duration

The existence of PVC pipes absolutely relies upon the nature of unrefined components and the level of fillers utilized in the lines. 

Though the existence of a CPVC pipe is nearly 50 years relying upon the line quality with the purpose of its usage.

  • Material Type

The material used to make PVC pipes are PVC gum + added substances [lead utilized as a handling aid]. 

The CPVC pipes are made up of lead-free finished compounds that make them strong and offer water-resisting certification.

  • Effect on Water

PVC pipes use lead as a treatment aid that is unsafe for human utilization. Likewise, these lines are different from what the national sanitation foundation confirmed. 

CPVC pipes utilize the tin as stabilizers that, make them consumable water affirmed.

  • Temperature

PVC pipes and PVC fittings are reasonable for temperatures under 50 degrees Celsius, which means that they can be utilized only in cold water applications.

CPVC lines can endure high temperatures up to 92 degrees Celsius, making them viable with both hot and cold water.

  • Breakage Chances

With time, the PVC pipes become weak as they are inflexible and loaded up with a high level of fillers. 

CPVC pipes have a low breakability. Even though the material is inflexible, the filler content is insignificant.

  • Plasticizer and Bendable Capacity

PVC pipes and fittings do not contain plasticizers and do not have the capacity to bend.

CPVC pipes are bendable and also composed of plasticizers.

  • Using for Drinking Water Purpose and Flexibility

PVC cannot be used to transmit water for drinking purposes, and it is a rigid material.

CPVC can be used for drinking water transmission, and it is also flexible.

  • Effect of Pressure

The chances of degradation in PVC Pipes are very high when each temperature point is raised.

The CPVC has the strength to handle the pressure at a high level and the chance of degradation is very less.

  • Quality

Without much care for the nature and quality of PVC pipes, the manufacturers overburden them with filler materials to remain seriously on guard and sustain themselves in the market.

CPVC pipes, the mixtures are pre-compounded and can’t be blended in with fillers. Additionally, the mixtures utilized for these lines are national sanitation foundation confirmed.

Wrapping it Up:

Thus, comparatively, the chlorinated polyvinyl chloride or CPVC pipes and fitting have more advantages for usage. So you are recommended to buy CPVC than PVC, as it contains many benefits for all kinds of uses.
