Hot Water Supply PPR Pipe System

Hot water supply PPR pipe systems are designed for residential, commercial, and industrial water supply and drainage systems. They can also be used for urban gas, power and fiber optic cable sheath, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

Features of hot water supply PPR pipe system
1. Light weight: density of 0.89-0.9g/cm3, greatly reduces the cost of transportation and construction strength of installation.

2. Healthy and non-toxic: PP-R material is entirely composed of carbon and hydrogen without adding any toxic heavy metal salt stabilizer, the health performance of the material has been tested and approved by national authorities.

3. Good heat resistance: when the working temperature is 70℃, it can be used for a long time, the short-term use of water temperature can reache to 95℃, the softening temperature is 140℃.
4. Long service life: under the rated use temperature and pressure, the service life of PP-R pipe material is more than 50 years.

5. Good corrosion resistance: in addition to a small number of oxidants, PP-R material can withstand corrosion of a variety of chemical mediums. It will not rust and corrode, and there is no bacteria, no electrochemical corrosion.

6. Good thermal insulation performance: because of the low thermal conductivity of PP-R material, the thermal conductivity of PP-R at 20℃ is 0.21-0.24W/mk, much smaller than that of steel pipe (43-52W/mk) and copper tube (333W/mk), so the heat preservation of the pipe is good.
7. The expansion force is small: because the elastic modulus of PP-R material is small, the expansion force due to temperature change is small, which is suitable for embedded walls and floor surface of direct buried mode.

8. The flow resistance is small: the inner wall of the pipe is smooth and will not scale, the grinding resistance coefficient is only 0.007, which is far lower than the metal pipe, the water capacity is more than 30% of the same specification of the metal pipe.

9. The system connection is firm: PP-R pipe system is firmly connected by hot melt connection, when the pipes and fittings of the same material are connected as a whole, the interface stretching, bending and impact strength are all higher than the strength of the pipe body, thus eliminating the hidden dangers of water leakage.

10. Green environmental protection: in the production, construction and use of the process, there isn't any pollution to the environment, it will not cause pollution problems.

11. Complete fittings: the PP-R pipe system has complete fittings, which can solve general engineering requirements with moderate cost. The price of PP-R pipe is lower than that of galvanized pipe.
