Polymer pipes have found a special place in various industries due to their light weight, good chemical resistance and economical price. Among these pipes, PVC, UPVC and CPVC are the most widely used. Although these three types of pipes are from the same polymer family, there are important differences in their structure, physical properties and applications. This article examines the differences between these three types of pipes in order to make the right choice for construction and industrial projects; a topic that has always been of interest to activists in this field, including Pars Polymer Company.
What is PVC pipe?
PVC stands for Polyvinyl Chloride. Regular PVC pipes are produced by adding plasticizers to make them more flexible. These pipes are commonly used in the following applications:
- Low Pressure Sewage Systems
- Cold Water Transfer
- Non-Industrial Applications
Advantages:
- Low price
- Easy installation
- Good corrosion resistance
Limitations:
- Low thermal resistance
- Reduced strength at high temperatures
What is UPVC pipe?
UPVC or Unplasticized Polyvinyl Chloride is a type of hardened PVC in which no plasticizer is used. Removing the plasticizer increases the mechanical strength and durability of the pipe.
Features and uses:
- Higher resistance than regular PVC
- Suitable for drinking water piping
- Widely used in building and sewage systems
Due to the lack of release of harmful chemicals, UPVC is considered a safe option for transporting drinking water, and many reputable manufacturers, including Polymer Pars Company, have a special focus on developing this type of pipe.
What is CPVC pipe?
CPVC, or Chlorinated Polyvinyl Chloride, is produced by chlorinating PVC. This process increases the pipe's thermal and chemical resistance.
Benefits and uses:
- High temperature resistance (up to about 90 degrees Celsius)
- Suitable for hot water transfer
- Widely used in chemical industries and advanced facilities
CPVC is an ideal choice for environments where the pipe is exposed to heat or harsh chemicals.
Feature PVC UPVC CPVC
Flexibility High Low Medium
Thermal Resistance Low Medium High
Mechanical Strength Medium High High
Main Application Wastewater and Cold Water Drinking Water and Building Hot Water and Industries
Conclusion
If you are looking for an economical pipe for simple applications, PVC is a good choice. For construction projects and drinking water transportation, UPVC will be a safer choice. In contrast, CPVC is considered the best option for hot water systems and certain industries due to its high thermal resistance. Understanding these differences helps in making the right choice and increasing the lifespan of the piping system; a topic that is always considered in the products and specialized consultations of Polymer Pars Company.
