CPVC PIPES & FITTINGS

SURYA CPVC plumbing system is a thermoplastic material made from CPVC compound and is manufactured as per Japanese Technology. It is long lasting and cost effective solution for the hot and cold water. Pipes are available in complete range from 1/2" to 2" sizes as per copper tube size (CTS). Pipes are available in sizes SDR 11 and SDR 13.5 as per IS 15778 and Fittings in SDR 11 as per ASTM D-2846. Threaded inserts in the transition fittings are made from brass withstand chemical corrosion at the elevated temperatures. The choice of the Raw material, the structural accuracy and the strict quality control give the Surya CPVC system a high degree of reliability which is the most suitable, easy and economic solution for transportation and distribution of potable water. It is technically superior, cost effective and offers many advantages over metallic and other conventional systems.

Support spacings are a function of pipe size operating temperatures, the location of heavy valves or fittings and the mechanical properties of the pipe material.
All piping should be supported at interval sufficiently close to maintain correct pipe alignment and to prevent sagging or geade reversal. Pipe should also be supported at all branch ends and at all changes of direction.
NOTE: The above information provides general guidelines. It should be used only as a reference and not as a guarantee of performance. Specific installation instructions and techniques may be required as a result of local plumbing and building codes, engineering specifications and instructions.
