Article Introduction
In the pipe market, CPVC pipe’s main competitor is polypropylene (PPR pipe). PPR is relatively new to the market, which has some homeowners, plumbers and trades questioning which product is better for their homes.
If you are considering CPVC pipes or PPR pipes for your piping system, the following article will give you some information on how to choose !
PPR Pipes vs CPVC Pipes
Temperature resistance:
CPVC pipes: The operating temperature of CPVC pipes can reach up to 93-100℃, which is 30-40℃ higher than PVC. It can withstand higher temperatures and is suitable for high temperature environments.
PPR pipes: PPR pipes have excellent high temperature resistance and can be used for a long time at a high temperature of 70℃ and can withstand instantaneous high temperature shocks of 95℃.
Corrosion resistance:
CPVC pipes: CPVC has excellent corrosion resistance and can resist chemical corrosion from strong acids, strong alkalis, salts, fatty acid salts, oxidants and halogens.
PPR pipes: PPR pipes have good corrosion resistance, but not as good as CPVC pipes.
Service life:
CPVC pipes: The service life of CPVC pipes can reach 50 years and has excellent aging resistance.
PPR pipes: The service life of PPR pipes is also longer, but not as good as CPVC pipes.
Application scenarios:
CPVC pipes: Due to their excellent high temperature resistance and corrosion resistance, CPVC pipes are widely used in the manufacture of various industrial pipes, hot and cold water pipes, and fire protection pipes.
PPR pipes: PPR pipes are mainly used for hot and cold water pipe systems in homes and commercial buildings, especially for hot water pipes.
Price:
CPVC pipes: Due to the high material and processing costs, the price of CPVC pipes is usually higher than that of PPR pipes.
PPR pipes: The price of PPR pipes is relatively low and more suitable for users with limited budgets.
Antimicrobial and Drinking Water Safety Issues
Bacterial Growth:
Despite disinfection, bacteria may still be present in your drinking water or hot water and may grow inside the pipe walls. When using CPVC piping systems, the smoothness of the pipe surface and the lack of plasticizers hinder the growth of microorganisms. Several international studies have confirmed that CPVC piping systems have better antimicrobial properties than other piping materials, especially PPR.
Drinking Water Safe：
CPVC is certified for drinking water applications by all major international agencies and holds NSF 61 Annex G certification. NSF/ANSI 61 focuses on cold water/drinking water system components and corresponding health effects, with a particular focus on lead. It was established to control the potential adverse effects on human health from products that come into contact with drinking water.
Environmentally Friendly and Sustainable
Compared to other plastic materials, including PPR pipe, CPVC pipe has a lower petroleum content. This means it requires less energy in the manufacturing process. At the end of its useful life, it can be reground into pellets and recycled into new pipes, or turned into things we use every day – floor padding, floor coatings, speed bumps, car mats, and more.
Summary
In summary, the choice of CPVC pipes or PPR pipes depends on the specific application requirements. If higher temperature resistance, stronger corrosion resistance, and safer drinking water safety are required, and the budget is sufficient, CPVC pipes are a better choice. If it is mainly applied to domestic hot water pipes and the budget is limited, PPR pipes are more suitable.
