PPR Pipe Fittings PPR Flange Core ISO9001 DIN8077/8078 Colour OEM size 40-160mm
PPR fitting manufactured from Polypropylene Random Copolymer raw material. The most important feature of PPR that distinguishes it from the others is that it could also be used in hot water systems besides being used in sanitary networks.
PP-R fitting is light, anti corrosive, anti-scaling and durable as ordinary plastic pipes and also has following main features:
1. Non-toxic and hygienic. Raw materials for PP-R fitting only contain carbon and hydrogen elements, and no harmful and toxic elements exist. Thus, PP-R fitting is hygienic and reliable. It is applicable not only to cold and hot water pipeline, but also to pure drinking water system.
2. Thermal insulating and energy saving. The thermal conductivity of the PP-R fitting is 0.21w/mk, which is only 1/200 of that of steels'.
3. Heat resistant. The vicat softening point of the PP-R fitting is 131.5 °C . The highest working temperature is up to 95 °C . It can meet the application requirements of hot water system in building water-supply and drainage standard.
4. Long service life. Under the condition that the working temperature is 70 °C and the working pressure is 1.OMP, the PP-R fittings' service life is up to over 50 years; the service life may be up to over 100 years under normal temperature.
5. Easy to install and reliable to connected. The PP-R has good weld ability, and the pipe and fittings may be connected through hot melting and electric melting. It is convenient to install and has reliable joints. The connection parts are tougher than the pipe itself.
6. There are bar code label on the tube, can easy track product information.
