PP-R pipe as a new type of pipe material has the following performance characteristics:

1. Energy saving: The energy consumption of PP-R pipe is only 20% of that of steel pipe, and its thermal conductivity is low [0.2W/（M.K）], only 1/200 of that of steel pipe. When used in hot water systems, it will greatly reduce heat loss.

2. Corrosion resistance, scale-free, hygienic, non-toxic: Using PP-R pipe can eliminate the internal scale and rust caused by galvanized steel pipe, and avoid water quality "secondary pollution". Due to the simple composition of PP-R, the basic components are carbon and hydrogen, which comply with food hygiene regulations, non-toxic, and more suitable for drinking water transportation.

3. Heat resistance, pressure resistance, long service life: The long-term use temperature of PP-R pipe reaches 95℃, and the short-term use temperature can reach 120℃. Under the condition of using temperature of 70℃ and working pressure of 1.2MPa, the service life can reach more than 50 years.

4. Lightweight, high strength, low fluid resistance: The density of PP-R pipe is only 1/8 of that of metal pipe, the pressure resistance test strength is as high as 5Mpa, and it has good toughness and impact resistance. Due to the smooth inner wall, no rust, no scale, and low fluid resistance.

Product features:

1. Non-toxic, hygienic.

The raw material molecules of PP-R contain only carbon and hydrogen elements, without harmful and toxic elements, which are sanitary and reliable. It can be used not only for hot and cold water pipes, but also for pure drinking water systems.

2. Insulation and energy saving.

The thermal conductivity of PP-R pipe is 0.21w/mk, only 1/200 of that of steel pipe.

3. Good heat resistance.

The Vicat softening point of PP-R pipe is 131.5℃. The high working temperature can reach 95℃, meeting the requirements of hot water systems in building drainage specifications.

4. Long service life.

Under the conditions of working temperature of 70℃ and working pressure (P.N) of 1.OMPa, the service life of PP-R pipe can reach more than 50 years; at room temperature (20℃), the service life can reach more than 100 years.

5. Easy installation, firm connection.

PP-R has good welding performance, and pipes and fittings can be connected by hot melt and electrofusion. It is easy to install, the joints are firm, and the strength of the joints is greater than that of the pipes themselves.

6. Material can be recycled.

PP-R waste can be recycled after cleaning and crushing for the production of pipes and fittings. The amount of recycled material does not exceed 10% of the total amount, and does not affect the product quality.

Main uses:

1. Cold and hot water systems in buildings, including central heating systems;

2. Heating systems in buildings, including floor, wall, and radiant heating systems;

3. Direct drinking pure water supply systems;

4. Central (centralized) air conditioning systems;

5. Industrial pipeline systems for conveying or discharging chemical media, etc.
