Problems using PPR pipes
Sep.23.2023
PPR (polypropylene random copolymer) pipe is a pipe material commonly used in hot and cold water supply systems. It has good heat resistance, pressure resistance and corrosion resistance. Here are some common questions and answers related to the use of PPR pipes: Can PPR pipes be used in cold water systems?
Yes, PPR pipes can be used in cold water systems. It has high pressure resistance and corrosion resistance and is suitable for cold water supply pipelines.
Can PPR pipes be used in hot water systems?
Yes, PPR pipes can also be used in hot water systems. It has excellent heat resistance, can withstand high temperature water flow, and is suitable for hot water supply pipes.
What are the advantages of PPR pipes?
PPR pipe has the following advantages:
Heat resistance: PPR pipes can withstand high-temperature water flow without softening or deformation.
Pressure resistance: PPR pipes have high pressure resistance and can withstand a certain amount of water pressure.
Corrosion resistance: PPR pipes have good resistance to common chemicals and corrosive media.
Long service life: PPR pipes have a long service life, usually more than 50 years.
Easy to install: PPR pipes are light in weight, simple to connect, and easy to install.
What are the sizes and specifications of PPR pipes?
The sizes and specifications of PPR pipes may vary according to different countries and regions. Generally speaking, the diameter of PPR pipes ranges from 20mm to 110mm, and common specifications are 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm and 110mm.
What are the connection methods of PPR pipes?
The main connection methods of PPR pipes are as follows:
Hot melt connection: Use a hot melt welder to heat and join the pipes together to create a strong connection.
Electrofusion connection: A connection made using an electrofusion welder, similar to a heat fusion connection, but using electricity instead of heat fusion.
Threaded connection: Connecting pipes together through threaded joints, suitable for smaller diameter pipes.
Note: The above answers are for reference only. PPR pipes should be selected and used according to local standards and specifications. During installation and use, it is recommended to follow relevant safety operating procedures and consult a professional pipeline engineer or supplier for advice.
