A high-quality pipeline should not only have good durability, but also be economical and practical, but also have a series of advantages such as stable and reliable interfaces, anti-cracking, anti-aging, corrosion resistance, and its material anti-impact. Compared with traditional pipes, the PP-R piping system has a series of advantages as follows:
One is sanitation and non-toxic. Polypropylene is a polyolefin compound with carbon and hydrogen elements in its molecule, non-toxic, tasteless, and reliable in hygiene. This product will not cause adverse effects on the human body and the environment during the whole process of raw material production, pipe forming, use and disposal. The additives added also meet the requirements of food hygiene. It is the same as the green environmental protection pipe of the polyethylene pipe, and it is suitable for cold storage. Hot water system is also suitable for pure water system.
The second is heat insulation and energy saving. The Vicat softening point of the aluminum-lined plastic PP-R pipe is 131.3℃, and the working temperature of the aluminum-lined plastic PP-R pipe is as high as 95℃. It can be used normally for 50 years under the conditions of 1 MPa and 70℃, which fully meets the design specifications for building water supply and drainage. Requirements for hot and cold water systems. The thermal conductivity of this product is 0.21 W/(m. k), which is only 0.5% of the thermal conductivity of steel pipes. It has good thermal insulation performance and can be used in hot water and heating systems to save a lot of energy.
Third, the wiring installation is simple and reliable. The aluminum profile PP-R lined pipe and pipe fittings are made of the same raw materials, and have good hot-melt welding performance. Hot-melt connection and electro-fusion connection can be used, the connection is simple, and the strength of the joint is greater than the strength of the pipe body. Compared with the mechanical connection method, this connection method is low in cost, fast in speed, simple in operation, safe and reliable, and is especially suitable for direct-buried and concealed installation occasions, without the need to consider whether there is leakage in the connection during long-term use.
The above are the advantages of aluminum alloy-lined PP-R pipe. The pipe is hygienic, non-toxic, energy-saving and heat-preserving, and its connection is simple and quick. It is especially suitable for direct-buried and concealed installation occasions.
