PP-R pipe、fitting apply field
"SHSU"PP-R pipes manufactured by Shanghai ShangSu Holding Group are widely used for installing the new construction pipeline system and changing the current water network pipeline system. They serve for following fields;
● Hot&cold water facilities served for civil buildings,such as:dwelling house air port,hospital,hotel.office,school,marine facilities,etc.
● Industrial pipe networks of food,chemical as well as electron,for instance,pipe network for carring kinds of corrosive liquid like acid,goaf water and deionized water；
● Drinking water(like pure water,mineral water,etc.) production system pipe networks；
● Pipes for air-conditioning device；
● Residence warming pipes；
● compression air pipe networks for factories；
● Pipe networks for swimming pools；
● Pipe networks for solar energy facilities；
● Conveying system for agriculture and gardens production
PP-R pipe 、fitting product performance
Water supply Poly: Propylene Random(PP-R)pipe for construction with international leading level, which is of environmental protection and saves the energy has following features：
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 70o C.
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.
Complete setting：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.
Reasonable price：The price of PP-R pipe is equal to that of galvanized pipe, but it is more convenient in construction,even the construction price is lower。
