PVC pipes are produced by extrusion process followed by calibration to ensure maintenance of accurate internal dia with smooth internal boxes. These pipes generally come in lengths of 6 meters. A wide range of injection moulded fittings, including tees, elbows, reducers, caps, pipes saddles, inserts and threaded adaptors for pipe sizes 15-150 mm are available. The PVC pipes are much lighter than cast iron or A. C. pipes. Because of their lightweight PVC pipes are easy to handle, transport, and install. PVC pipes have elastic properties and their resistance to deformation resulting from earth movements is superior compared to conventional pipe materials especially asbestos. Thermal conductivity of PVC is very low compared to metals. PVC pipes are available in sizes of outer dia 20, 25, 32, 50, 63, 75, 90, 110, 140, 160, 250, 290, 315 mm at working pressure of 2, 5, 4 and 6, 10 Kg/cm2.
The demand estimates for all polymers including engineering polymers was envisaged to increase from 7.5 mn tonne in 2006-07 and to 9.5 mn tonne in 2009-10. It was projected at close to 14 mn tonnes in 2014-15. India is one of the fastest growing polymer market in the world, and is expected to become the world's third largest polymers market, with a consumption of 12.5 mn tonne, after the US and China, by 2010. At present, the US is the largest market in the world consuming 27.3 mn tonne of polymer products. Thus, as an entrepreneur this project offers an exciting opportunity to you.
