Can the PPR pipe be used as a heating pipe?

PPR pipe is a new type of water pipe material, which can be used as cold water pipe and hot water pipes. In the water pipe industry, PPR pipe is very popular, so can PPR pipe be used as a heating pipe? IFAN will answer for everyone! This is our Facebook Website:www.facebook.com

Advantages of PPR pipe

PPR pipe has unique advantages. It can be used as a cold water pipe or hot water pipe. Because of its advantages of non-toxicity, lightness, pressure, and corrosion, it is becoming a material popularized in many decoration projects. In many decoration projects, PPR pipes have been widely used, not only for cold water pipes, but also for hot water pipes, and even for pure water pipes.

The PPR pipe interface adopts hot-melt technology, and the pipes are fully integrated. Therefore, once the installation and pressure test pass, there will be no aging water leakage like the aluminum-plastic pipe, and the PPR pipe will not scale. PPR pipe is a green high-grade water supply material that never scales, never rusts, and never leaks.

PPR pipes are very popular in the plumbing industry, but IFAN reminds everyone that PPR pipes cannot be used as heating pipes. Since the expansion coefficient of the PPR pipe is very large, about 0.15 mm/m? ℃, which means that when the external temperature (such as winter and summer) or the internal water temperature (cold and hot water) changes, the deformation will be large. Because the PPR pipe is a rigid straight pipe, it cannot absorb the deformation, so it is easy to form bending deformation or even leak piping system.


In terms of water supply, the long-term operating temperature of PPR pipes is low (70°C), so it is bound to be limited in terms of hot water delivery. If it is a heating system, since the long-term operation of the system has a water temperature above 70°C, the PPR (polypropylene) pipe used as a hot water pipe has obvious shortcomings in anti-aging, and leakage will occur at the joint after a period of operation.

In addition, thermal expansion and contraction have a great impact on the metal joints of PPR. It is best not to use PPR pipes as floor heating pipes or heating pipes, but to choose PE-RT pipes and other pipes as floor heating pipes or heating pipes.

Advantages of floor heating pipes:

Comfortable and hygienic

Comfort, hygiene, and health care. The floor heating pipe makes the indoor surface temperature uniform, and the room temperature gradually decreases from bottom to top, giving people a good feeling of warming the feet and cooling the head; it is not easy to cause dirty air convection, and the indoor air is clean; it improves blood circulation and promotes metabolism.

Save space

Save space and beautify the living room. The radiator and its branch pipes are canceled indoors, which increases the usable area, facilitates decoration and home furnishing, and reduces sanitary corners.

Energy efficient

High efficiency and energy saving. Users can adjust and control according to the situation to effectively save energy.

Good thermal stability

Good thermal stability. Floor heating pipes heat the ground layer and concrete layer with large heat storage and good thermal stability. Under the condition of intermittent heating, the indoor temperature changes slowly.
