PPR hot water pipe
PPR water pipes, officially known as polypropylene random copolymer (PP-R) pipes, are pipe materials made by extrusion molding from the copolymer of propylene and ethylene. This material's molecular structure characteristics give it inherent excellent high-temperature and high-pressure resistance, making it particularly suitable for use as connection pipes for heating systems, water heater pipelines, and other applications that require the transportation of hot water. Currently, most PP-R pipe materials on the market are produced in accordance with the national standard GB/T 18742, with outer diameters ranging from 20mm to 160mm and various specifications available.
How to distinguish between cold and hot water pipes
Look at the identification lines: This is the most intuitive method. The outer wall of the PPR hot water pipe is usually marked with red lines, while the cold water pipe has blue lines.
Wall thickness of the pipe: Under the same outer diameter, the wall of the hot water pipe is thicker than that of the cold water pipe. For example, for the same DN20 pipe, the wall thickness of the cold water pipe might be 2.3mm, while the hot water pipe would need 2.8mm or 3.4mm. This is because the hot water pipe needs to withstand higher pressure and temperature.
Why Choose PPR Pipe
- Hygiene and health
The pipes are completely non-toxic both inside and outside, meeting the hygiene standards for drinking water. There is no need to worry about secondary pollution of the drinking water. - Corrosion resistance
It can resist the erosion of acidic and alkaline substances in water, does not rust, and greatly extends its service life. -
Non flouling behaviour
The inner wall of the pipe is very smooth, with low water flow resistance. Even after long-term use, it will not form scale on the inner wall like metal pipes, thus ensuring smooth water flow. -
Heat preservation and heat insulation
The PPR material has poor thermal conductivity. When used for hot water pipes, the heat loss is very small, and it inherently has a certain degree of insulation effect. -
Heat and pressure resistant
Under the conditions of long-term transportation of 70℃ hot water and working pressure of 1.0 MPa, it can be safely used for over 50 years. The maximum short-term operating temperature can reach 95℃. -
Reliable connection
Using the hot-melt connection technology, the pipe material and pipe fitting are heated and fused together. The strength at the connection point is even higher than that of the pipe material itself, completely eliminating the risk of water leakage. -
Shock resistanc
The material has good toughness and excellent impact resistance at low temperatures, and it is not prone to cracking. -
Sound insulation and noise reduction
The PPR material has excellent sound insulation properties and can effectively reduce the noise caused by water flow. -
Portable and easy to install
The weight is only 1/8 of that of the metal pipe, making it extremely convenient for transportation and construction
