Performance Characteristics Of PPR Pipe

Good corrosion resistance: Except for a few oxidants, it is resistant to erosion by various chemical media, will not rust, will not corrode, will not breed bacteria, and has no electrochemical corrosion.

Good heat resistance: when the working water temperature is 70 degree , it can be used for a long time, the short-term use water temperature reaches 95 degree , the softening temperature is 140 degree , and the weight is light. The density is 0.89~0.9g/cm3, which is only one-ninth of the steel pipe and one-tenth of the copper pipe. Due to the light weight, the transportation cost and the construction strength of the installation can be greatly reduced.

Hygienic and non-toxic: PP-R material is completely composed of carbon and hydrogen, without adding any toxic heavy metal salt stabilizer, and the hygienic performance of the material has been tested by the national authoritative department.

Long service life PPR pipes have a service life of more than 50 years under the rated operating temperature and pressure.

Small water flow resistance: The inner wall of the pipe is smooth and will not scale. The friction coefficient is only 0.007, which is much lower than that of metal pipes. The water passing capacity is more than 30 percent higher than that of metal pipes of the same specification.

Good thermal insulation performance: Due to the low thermal conductivity of PP-R material, the thermal conductivity at 20 degree is 0.21 ~ 0.24W/mk, which is much smaller than that of steel pipe, so PP-R pipe has good thermal insulation performance.

Small expansion force: Due to the small elastic modulus of PP-R material, the expansion force caused by temperature changes is small, and it is suitable for direct burial and concealed laying in embedded walls and floor surfaces.

System connection is firm: PP-R pipes are connected by hot-melt connection, connecting pipes and fittings of the same material into a whole, and the tensile, bending and impact strength of the interface are higher than the strength of the pipe body, thus preventing water leakage hazard.
