1. Non-toxic, hygienic, corrosion-resistant, non-scaling. PP-R raw material molecule only carbon and
hydrogen elements, no harmful and toxic elements exist, sanitary and reliable, in the production, cons-
truction and use process of environmental pollution-free, belongs to green building materials. It can
be used not only in hot and cold water pipelines, but also in pure drinking water systems. It can avoid
the worry of macular rust stains in water basins and bathtubs caused by pipeline corrosion, and avoid
the blockage caused by pipeline corrosion and scaling.
2. High temperature resistance, high pressure resistance, heat preservation and energy saving: When
the working water temperature is 70 degrees, it can be used for a long time, and the short-term water
temperature can reach 95 degrees. The Vicat softening point of PP-R pipe is 131.5 degrees. The worki-
ng temperature can reach 95 C, which can meet the requirement of hot water system in building water
supply and drainage code. The thermal conductivity is only 2% of that of the metal pipe, which is very
good for heat preservation and energy saving of the hot water pipe.
3. Light weight, beautiful appearance, only one seventh of the proportion of metal pipe, light weight,
greatly reducing the construction intensity. The inner and outer walls of the product are smooth, the
fluid resistance is small, the color is soft and the shape is beautiful.
4. Installation is convenient and reliable, service life factory, hot melt connection, several seconds to
complete, safe and reliable. Under the prescribed service conditions, the service life can be more than
50 years, and under the working pressure (P.N) of 1.0 MPa, the service life can be more than 50 years
(provided that the pipe must be of the series of S3.2 and S2.5), and at room temperature (20 C), the
service life can be more than 100 years.
