what's pp-r pipes

PP-R pipe as a common pipe water supply system is widely used in various construction industries, including residential domestic piping systems, hotels and shopping malls water supply projects, etc.

It is one of the most energy-efficient and environmentally friendly plastic pipe products, so how much do you know about the PPR pipes you use? How to choose the best PP-R pipes or fittings for your project?

Content Quick View

PP-R pipe (type III polypropylene pipe), using random common polypropylene as raw material, and then add the appropriate amount of antioxidant, nucleating agent and other mixing and stirring, and then after cooling and other processes, pressed into a pipe.

It can be used with almost all hot and cold water systems, and is now an integral part of the home plumbing system. ppr pipes and fittings are made of non-toxic, odourless, high-quality materials, which are able to withstand extreme temperatures ranging from -20°C to 95°C. The colours are usually green and white.

Each size of pipe comes with a set of fittings for the corresponding size, and it is an essential part of modern plumbing systems for a wide range of hot and cold water systems.

  1. Heat-resistant: PP-R pipes can work at temperatures up to 95°C, meeting the requirements for the use of hot water systems in the building water supply and drainage code.
  2. Environmental protection and non-toxic: PPR plastic pipe raw material molecules only carbon and hydrogen elements, there is no harmful and toxic elements exist, reliable hygiene performance, not only for hot and cold water pipelines, but also for pure drinking water system.
  3. Corrosion resistance: PP-R pipe does not produce chemical effects on most of the ions in the water and chemicals in the building, and will not rust, corrode, breed bacteria, and will not be scaled and clogged.
  4. Thermal insulation and energy saving: PP-R pipe has low thermal conductivity, only 1/200 of steel pipe, good thermal insulation performance, which can minimise heat loss or heat gain in the transmission of hot and cold fluids.
  5. Convenient installation: the installation can be connected by heat fusion, convenient, safe and reliable, the weight is also smaller than the metal pipe, which can greatly reduce the operating time, and the difficulty of installation.
  6. Long-lasting: PPR pipe in the normal working environment and use conditions, the service life can reach more than 50 years.
  7. Maintenance-free: ppr pipe and fittings connected by heat fusion, the probability of leakage is almost zero, which means that the later maintenance costs will be greatly reduced.


  • PP-R pipe also has some non-negligible disadvantages, long-term working temperature can not exceed 70 ℃, the length of each section is limited and can not be bent construction. Therefore, when choosing and using PPR pipe, you need to make comprehensive consideration according to the actual needs and conditions.

> Application of PP-R pipes

Modern hot and cold water systems

  • PP-R pipe is non-toxic, environmentally friendly, lightweight, is the first choice of water pipe materials in home decoration, water supply system in industrial buildings, drainage systems, can use PPR pipe for connection.PPR pipe’s excellent performance can ensure the safety and reliability of the building’s water supply, to improve the effectiveness of the use of hot and cold water systems and life.

Chemicals and corrosive fluids transport:

  • PP-R pipe is corrosion-resistant, not easy to scale, and can be used to transport all kinds of acid and alkali liquids, water, salt water and so on. In chemical, petroleum, electric power and other fields, PPR pipe can replace the traditional steel pipe and plastic pipe, improve the conveying efficiency and reduce the maintenance cost.

Agricultural irrigation:

  • PP-R pipes are pressure-resistant, corrosion-resistant and lightweight, and can be easily laid in agricultural fields to provide crops with sufficient water. At the same time, the environmental performance of PPR pipe is also in line with the requirements of sustainable development of modern agriculture.

Infrastructure development:

  • PPR pipes are widely used in infrastructure projects such as sewage systems, drainage systems and cable conduits due to their excellent corrosion and abrasion resistance. It can ensure the long-term stable operation of infrastructure projects and improve the reliability and safety of the overall system.

> Summary

Regardless of the material of the pipe, it has its advantages and disadvantages. In engineering, pipes need to be selected according to their characteristics and in conjunction with the actual situation.
