detailed product description our pp-r system provides combination of benefits in handling cold and hot water, as it provides: 1) long durability due to the high resistance to aggressive elements, which gives the system extremely long service life of 50 years and more 2) incomparable smooth and porosity-free internal surface of both pipes and fittings, which results in a very low pressure loss and absence of incrustation (reduction of section due to the limestone and scaling) 3) nontoxic and physiologically harmless material 4) resistance to bacteriological attack thus enabling safe potable water transfers 5) resistance to wide range of chemicals and so corrosion is avoided in service lines 6) good impact strength so as to be used in all environments and around buildings 7) heat preservation and energy-saving abilities 8) the heat conductivity of pp-r pipes is much lesser than metals and hence offers significantly high levels of heat preservation for transported fluids 9) high acoustic insulation against fluid noise 10) the fluid flow and hydraulic shocks with in the building create noise which can be very well avoided by the noise absorption ability of pp-r materials 11) lighter weight compared to the metallic piping systems (1/9 of the steel specific gravity) 12) convenient and reliable installation methods 13) the pp-r pipes can even be installed in suspended form under ceiling without problem of flexion 14) easy connectivity over a complex network 15) no perforation caused by electrical currents 16) no furring while cutting 17) cost effective pipeline network 18) safe environment with recyclable ability our pp-r system can be used for: 1) hot and cold potable water piping networks in residential and commercial building, such as hospitals, hotels, offices, and school buildings 2) chilled water networks in air conditioning systems, as an effective light weight and corrosion free substitute for steel pipes 3) transport of wide range of chemicals in the industry 4) irrigation systems for gardens 5) piping networks for rainwater utilization systems 6) piping networks for swimming pools facilities 7) compressed air installations 8) piping networks for solar plants
