Features
Specifications

Non-Toxic and Hygienic -C.R.I. uPvc pressure pipes are most ideal for carrying potable water.
Corrosion Resistance – These pipes are not affected by chemical, electrolytic and galvanic action, hence free from corrosion.
Smooth Surface – Pipes are having mirror smooth inner surface and hence better flow characteristics in comparison to AC, CI & GI pipes.
Fire Resistant – C.R.I. uPVC pressure pipes are fire resistant and self-extinguishing.
Maintenance Free – These pipes & fittings are free from corrosion, rust, weathering & leakage and ensures years of trouble free performance
Strong & Light Weight -The pipes are light in weight for easy handling and have good mechanical strength & toughness.
Longer Life – The system is free from weaknesses caused by rusting, weathering and chemical action, and hence lasts for a lifetime.

Note : The wall thickness of pipe is based on a safe working stress of 8.6 MPa at 27"C. The working pressure gets reduced at sustained higher temperatures. Occasional rise in temperature, as in summer, with concurrent corresponding reduction in temperature during nights has no deleterious effect on the working pressure of the pipes considering the total life of pipe.
