(1) application scope of PP-R pipe: cold and hot water system in civil and industrial buildings. Industrial compressed air pipe network system, drinking water system and food industry piping system. Irrigation and pipe network systems for gardens and greenhouses.
(1) application scope of PP-R pipe:
Cold and hot water systems in civil and industrial buildings.
Industrial compressed air pipe network system
Irrigation and pipe network systems for gardens and greenhouses.
Traditional heating and heating piping system.
Central air conditioning piping system.
(2) The water supply equipment manufacturer will bring you to understand the true and false PP-R water supply equipment PP-R cold and hot water supply pipe advantages:
Lightweight: Density of 0.89-0.92g/cm 3, due to light weight, can greatly reduce the cost of transportation and installation of construction intensity.
Good heat resistance: instant water temperature can reach 95 degrees Celsius. It can be used for a long time at 75 water temperature. It is an ideal indoor hot and cold water pipe.
Long service life: PP-R pipe at normal ambient temperature, working pressure 10KG / cm 2, its service life longer than other materials made of pipe.
Good corrosion resistance: for most of the ions in the water and chemical substances in buildings do not produce chemical effects, will not rust, corrosion, bacteria breeding.
Low thermal conductivity: the thermal conductivity is 0.23-0.24 W/mk at 20 C, much smaller than steel pipe and copper pipe, so PP-R pipe has good thermal insulation.
Recyclability: In the production, construction, use of the process of no environmental pollution, waste can be recycled repeatedly, belonging to green building materials.
Complete supporting: PP-R pipeline system is complete, can solve indoor and residential water supply pipeline engineering requirements.

(3) how to identify the authenticity of PP-R water supply pipes.
How to identify the authenticity and the prevention of PP-R water supply pipes can be identified by the following methods:
First, intuition and measurement. The inferior products have bright luster, strong plasticity, rough processing, unstable tolerance, easy to appear "ripple", "hemp" and uneven color. The quality products are uniform in color and color, Hikaruzawa Akiahikaru is more soft, and the processing accuracy is higher. The color difference between the superior and inferior products is more obvious.
2. In actual welding, because of the different physical and chemical indexes of different raw materials, the melting time of high-quality PP-R pipe and fittings is longer, the insertion viscosity and tension of the welded joint is bigger, and the welding is more difficult; on the contrary, the hot melting time of the low-quality PP-R pipe and fittings is shorter, and the viscosity and tension of the welded joint is lower, so it is very labor-saving.
3. According to the different characteristics of the melting point of the material, the pipe will be placed in 15 you oven heating 1-2 hours, there is no sign of melting is a false P P-R pipe.
