THERMAL EXPANSION OF THE SYSTEM
In PP-R, deformation due to expansion are absorbed due to "low elastic modulus" of the pipe material.Therefore no real problems are envisaged due to expansion in concealed installations.In case of external applications on ceiling or walls, where long lengths are installed, the effects of expansion contractions shall be considered while assembly of indo green system. This problem can be solved either byusing suitable expansion loops or clamps. (for more detail please refer to our assembly regulation manual).
HEAT LOSS AND INSULATION REQUIREMENTS
Due to the low thermal conductivity of indo green PP-R (0.21 W/mK) normally it may not be necessary to insulate, when used for hot water concealed application. However, for application where central boiler is used for distribution of hot water, and the circulation of hot water being continuous, it is necessary to insulate distribution lines to prevent excessive loss of heat and energy wastage.
POLYFUSION WELDING
Joints of the indo green pipes and fittings are usually jointed together by poly-fusion welding, which is a fundamental property of this system. This process consists of mixing of melted material of external surface of the pipe and internal surface of the fitting, after heating them up to 260 °C to 280 °C on the small welding machine called poly-fusion device. Properly made welded joint, when cut through, shows no traces of contact surface between two elements i.e. pipe and fitting in the entire volume of joint. Thus fusion process gives homogeneous, integral, long lasting, leak proof joints.
Light weight, easy and quick assembly
which results in extensive saving on time and labour.
Safest system for carrying drinking water
PP-R is absolutely free from corrosion and negative biological effects. It does not break down even under the harshest of water conditions, hence the quality of water never deteriorates. It is in full compliance with the International standards on the use of plastics materials for the transportation of potable water.
Excellent resistance to corrosion and chemical attacks
PP-R pipes and fittings are stable against the majority of known aggressive and toxic chemicals, aggressive soils and fluids in the external environment.
Reduced head loss
Mirror smooth inside surface ensures high flow rates and very low frictional losses.
Low thermal conductivity
which results in saving on insulation cost, thereby reducing overall operational costs.
Free from scaling
Due to the unique properties like extremely smooth surface, non-polar nature of the material, and low surface energy of the PP-R, limestone or other deposits cannot form and hence there is no scaling or blockage in the pipelines, throughout the life of the piping system.
High impact strength
Indo green PP-R has a very good impact strength.
Low on sound
The sound-dampening property is a major attraction in plumbing, flushing and pressurized flow applications.
Long operational durability
Indo green system ensures a minimum 50 years of trouble free performance.
Overall Economy
This system is most cost effective than any other plumbing system. Moreover, due to savings in installation and insulation costs, this system is even comparable with standard make G.I. B class piping system.
Besides above stated benefits, it has very good resistance to frost, abrasion and stray current, and is considered to be most suitable in seismic areas.
