The company is committed to producing high-quality R pipes, R pipes, R pipes, R floor heating pipes and other series of products. You can learn more through the following methods!

Generally there will be no water leakage and the reliability is extremely high. But this does not mean that the R water pipe is a water pipe without defects. Its high temperature resistance and pressure resistance are slightly worse. The long-term operating temperature cannot exceed ℃. Each section has a limited length and cannot be bent for construction. If the pipeline is laid over a long distance or has many corners, A large number of joints are used in construction. Pipes are cheap but accessories are relatively expensive. In terms of comprehensive performance, R pipe is a cost-effective pipe material, so it has become the first choice material for home decoration water pipe renovation. Commonly used colors of R tubes: R tubes sold on the market mainly have the following colors, white, gray, green and curry color. The reason why there is this difference is mainly caused by the different color masterbatch added. It is generally recommended to buy white R-tubes, because a very small number of greedy manufacturers will use recycled materials to produce R-tubes and add color masterbatch to cover up defects caused by impure raw materials.
Recommendations for R-pipe installation:
Generally, during the renovation of water and electricity, the original water pipes will be replaced. Home decoration companies and merchants recommend that decorators use all hot-water pipes when installing R-pipes, even those that flow through cold water. The place also uses hot water pipes. Their argument is that because the technical parameters of hot water pipes are higher than those of cold water pipes, and the prices are not much different, hot water pipes are used in waterway reconstruction. The diameter of R pipes can range from If the economy allows, we recommend using pipes with an outer diameter of 1 mm (commonly known as branch pipes), especially the cold water pipes for incoming water, because modern families are highly concentrated in more and more water appliances, and the probability of using water is very high. May reduce the problem of low water pressure and low water flow.
Features of R pipe:
In addition to the characteristics of ordinary plastic pipes such as light weight, corrosion resistance, non-scaling and long service life, R pipe also has the following main features:
Green and hygienic. The raw material molecules of R only have hydrocarbon elements, and there are no harmful elements. It is hygienic and reliable. It can be used not only for hot and cold water pipes, but also for pure drinking water systems.
Insulation and energy saving. The thermal conductivity of R pipe is /, which is only / of steel pipe.
Better heat resistance. The Vicat softening point of R tube is ℃. The maximum working temperature can reach ℃, which can meet the usage requirements of hot water systems in building water supply and drainage regulations.
Long service life. The R pipe has a service life of more than 10 years under the conditions of working temperature ℃ and working pressure (provided that the pipe must be of series and above at normal temperature (℃)). The service life can reach more than 10 years under normal temperature (℃)
It is easy to install and the connection is reliable. R has Good welding performance, pipes and fittings can be connected by hot melt and electrofusion, easy installation, reliable joints, the strength of the connection part is greater than the strength of the pipe itself.
Materials can be recycled. R waste materials are recycled after cleaning and crushing It is used in the production of pipes and fittings. The amount of recycled materials does not exceed % of the total amount and does not affect product quality.
Advantages of R pipe
Light weight, the density is / at ℃, the weight is only one-ninth of the steel pipe, red copper One-tenth of the pipe, light weight, greatly reducing construction intensity.
Good heat resistance. The instantaneous operating temperature is ℃. When used for a long time, the temperature can reach ℃. It is currently the most ideal indoor hot and cold water pipe.< br /> Corrosion resistance, non-polar material, has no chemical effect on all ions in water and chemicals in buildings, and will not rust or corrode.
Low thermal conductivity, good thermal insulation properties, used for In hot water systems, there is generally no need for additional insulation materials.
The small pipe resistance and the smooth inner wall of the pipe make the resistance along the way smaller than that of metal pipes and lower energy consumption.
The pipe connections are firm and have good hot melt performance. Hot melt connection connects pipes and fittings of the same material into a perfect whole, eliminating the risk of water leakage.
Sanitary and environmentally friendly, it does not pollute the environment during production, construction and use, and is a green building material.
Application fields:
The building's hot and cold water system, including central heating system
The building's heating system includes floor siding and radiant heating systems
Directly drinkable pure water supply system
Central (centralized) air-conditioning system
Industrial piping systems for transporting or discharging chemical media.
Piping systems such as gas lines for cylinder transmission.
How to buy:
Real The R pipe shall comply with the standard B/Plastic piping system for hot and cold water Part 2 pipes and fittings shall comply with the standard B/Plastic piping system for hot and cold water Part 3 pipe fittings The performance of pseudo-R pipes and fittings is unable to pass the above standards. Should It is pointed out that the service life of pseudo R tubes is only 10 years, while the service life of real R tubes is more than 10 years.
