PPR Water Pipe

PPR water pipe is everywhere to see. PPR pipe is the most popular pipe for water supplying. PPR stands for Polypropylene Random Copolymer, a tough, flexible plastic material resistant to heat, pressure, and chemicals. Polypropylene is formed into pipes using a process called random copolymerization, which produces a strong molecular bond.

Under the current background of increasing environmental awareness, PPR pipe, as a green environmental protection product, has the characteristics of renewable and not easy to be polluted, and is favored by more and more markets. In the future, through technological improvement and innovation, PPR pipe fittings will have greater breakthroughs in pressure resistance, corrosion resistance, heat resistance and other aspects to provide a better use experience.

PPR pipe applying in cold and hot water supply in buildings, with variety of advantages as following:

(1)Light weight:

The density of the pipe is only 0.895-0.915g/cm3,which is only 1/9 of steel pipe and 1/10 of copper pipe. It makes handling and installation more convenient.

(2)Good heat and pressure resistance:

Its short-term operating temperature can up to 95°C. And under the temperature of 80°C, it still can bear some pressure for a long term. That's the best choice for cold and hot water supply pipeline in buildings.

(3)Long service life:

Under proper temperature and pressure, its service life can reach over 50 years.

(4)Good corrosion resistance:

PPR pipes have excellent corrosion resistance to most inorganic ion and common chemical substances in buildings. It is anti-corrosion and does not rust in long term use.

(5)Reliable and convenient connection:

PPR material has excellent melting welding performance. The pipes and fittings are made from the same material, joined together by melting welding. Compared to single pipe, the tensile, bending and impact strength in joint are much higher, which prevents the danger of leakage, and this kind of connection method also makes the site installation reliable and convenient.

(6)Nonpoisonous and harmless:

PPR belongs to polyolefin, which is a kind of thermoplastics, whose molecule is only composed of carbon and hydrogen. And the sanitary property of the materials for PPR pipes and fittings has been certificated by national authority organization.

(7)Good thermal and sound insulation property:

The thermal conductivity coefficient of PPR is 0.23w/m℃, which is only 1/200 of steel pipe (43-52w/m°C).No need to use insulating materials when used in hot water systems, which saves insulation materials and energy. And it has lower noise when water delivery in pipeline system.

(8)Better water passing capacity:

The smooth inner surface of PPR pipes and fittings have lower friction, which ensure fast running of the water.

(9)Environment-friendly building material:

During production, installation and application, no pollution will be caused to the environment.
