Why is PP-R fittings important to you?

PP-R fittings

PP-R fittings, or Polypropylene Random, is a chemical industrial material made of random copolymer polypropylene. This material is generally used in industries involving plumbing systems, where the main purpose is to join pipes together and to allow the different pipes to fit tightly together for sealing. PP-R fittings have a number of advantages over the common cast iron, cement and other plumbing materials, which allows the material to be used in a wide variety of industries related to plumbing, including construction and drainage, city gas, power and fiber optic cable sheathing, industrial fluid transfer, agricultural irrigation and other construction, municipal, industrial and agricultural fields. By using PP-R fittings in the construction of plumbing pipes, it ensures the reliability of the pipes and the great possibility of no more water leakage. In the following article, you will find more detailed information about PP-R fittings.

Main features of PP-R fittings

PP-R fittings, as a highly used industrial water pipe material, has a series of advantages and is less expensive, making it more cost-effective than other materials such as cement and cast iron pipes. Its main features include

Lighter weight: PP-R fittings are only one-ninth the weight of steel pipe and one-tenth the weight of copper pipe, and their lighter weight greatly reduces the intensity of construction.

Better heat resistance and insulation performance: PP-R fittings have excellent heat resistance and are ideal for indoor plumbing, with a maximum working temperature of 95 degrees Celsius. In addition, PP-R fittings also have good thermal insulation properties and generally do not require additional insulation materials when used in hot water systems.

High hygiene: The main chemical substances of PP-R fittings contain only carbon and hydrogen elements, and no harmful and toxic elements exist, so they can be used not only for hot and cold water pipes, but also for pure drinking water systems.

Long service life: PP-R fittings can last up to fifty years at a long-term temperature of 70 degrees Celsius. At room temperature of 20 degrees Celsius, PP-R fittings can last up to 100 years.

Corrosion resistance: PP-R fittings have no chemical effect on all chemicals in water and will not rust or corrode.

Easy installation and reliable connection: PP-R has good welding performance, pipes and fittings can be connected by hot fusion and electric fusion, which is easy to install and the joints are very reliable and not easy to fall off. This can also well eliminate the hidden danger of water leakage.

Common applications of PP-R fittings

As a universal plumbing material, PP-R fittings are often used in many industries. The following are the common areas of application for PP-R fittings.

  • Hot and cold water systems in buildings, e.g. central heating systems
  • Heating systems, including in-floor, wall panel and radiant heating systems
  • Purified water supply systems.
  • Central air conditioning systems.
  • Industrial piping systems for transporting or discharging chemical media

and others, etc.
