Product Characteristic                                                                                                   

• Light weight: Density is 0.89-0.92g/cm3 only 1/9 of steel pipe, 1/10 of purple steel pipe. Due to light weight,it can reduce the transportation cost and works for installing
• Long service life: Under the normal environment temperature,and the working pressure of PP-R pipe is 10kg/cm2 its service life is longer than other pipes made of different material, the reason is that it has the anti-heat performance( the service life is up to 50 years under 70℃.
• Good anti-corrosion property: The ion in the water and the chemical matter in the building can't make the pipe cause extra chemical reaction, it can't rust,erode,and bring the bacillus.
  Low thermal conductivity: Heat conduction is 0.23-0.24W/mk at 20oC, it is much lower than that of steel pipe(43-52W/mk) and purple steel pipe (333W/mk). 
• Strong heat resistance:  When the working water temperature is 70oC, It can be used for long time,when it is used for short term,the temperature reaches 95oC.
• Firm pipe fittings connection :Because polypropylene has fine thermal casting performance, thermal casting between the pipe and pipe fittings with the same material as a integration, it can prevent water leaking.
• Recycling property:During being produced, constructed and used, it has no pollution to environment, its waste can be recycled, it is belong to healthy product.

The mating of PP-R pipe system is complete, so it can meet the project mating requirement of water supply pipe in the room and residential district.
