CPVC pipe and UPVC pipe are two common plastic pipes, both of which have good corrosion resistance, high temperature resistance and aging resistance, so they have been widely used in many occasions. However, there are some significant differences between CPVC pipes and UPVC pipes, which are described in detail below.
1.Material Properties:
CPVC pipes are made of chlorinated polyvinyl chloride (CPVC) resin, while UPVC pipes are made of polyvinyl chloride (PVC-U) resin. Due to the chlorine atoms contained in CPVC resin, the heat resistance and aging resistance of CPVC pipes are better than those of UPVC pipes. In addition, CPVC pipes also have high rigidity and strength, so they are suitable for some high-pressure and high-temperature applications.
2.Thermal conductivity:
CPVC pipes have lower thermal conductivity than UPVC pipes, so CPVC pipes are more suitable for hot water delivery systems. In addition, the coefficient of expansion of CPVC pipes is low, so the deformation of the pipe is less when the temperature changes, making it suitable for use in floor heating systems.
3.Weather Resistance:
CPVC pipe is more weather-resistant than UPVC pipe because it contains chlorine atoms, which are better able to resist ultraviolet radiation. Therefore, CPVC pipes are more suitable for outdoor laying and direct burial applications.
4.Connection:
Both CPVC pipes and UPVC pipes can be glued and threaded. However, due to the low coefficient of expansion of CPVC pipes, certain measures need to be taken to eliminate the stress caused by temperature changes during installation.
CPVC pipes are more expensive to produce, so they are more expensive than UPVC pipes. However, CPVC pipes are more cost-effective from the perspective of long-term use due to their better durability and weather resistance.
There are certain differences between CPVC pipes and UPVC pipes in terms of material properties, thermal conductivity, weather resistance, connection methods and **. When selecting pipes, comprehensive consideration should be made according to the needs of actual applications to select the most suitable pipes.
