Abstract

Rigid PVC pipes produced in the country are hundred per cent indigenous as these are produced from PVC resin manufactured in the country. Each traditional piping material has an imported component either in its manufacture or in its use. CI pipes require imported lead for making joints although new jointing material is being evolved. AC pressure pipes require imported asbestos fibre to provide necessary tensile strength. GI requires zinc which again has to be imported. Hence considerable foreign exchange could be saved by using PVC pipes. It will be a very, very long time—if ever—for stasis to be reached in the exploration of new avenues for the use of PVC. A fascinating example of fresh fields being conquered by PVC is the evolution of PVC water stops for expansion joints in road bridges and construction joints—several times more economical and lasting than copper, monel, rubber, etc.

Abstract

In this article the author discusses briefly about PVC (Poly Vinyl Chloride) as pipe material for potable water supply. The physical, mechanical and other properties are presented for ready reference. The increased trend of usage of PVC pipes in water distribution systems in developed countries has been shown. Lastly the author suggests that PVC pipes should be used in India for water systems in urban and rural areas in view of the economy and overall efficiency of the PVC pipes compared to the conventional piping systems.

Abstract

The use of rigid PVC pipes for the distribution of potable water are gradually increasing its popularity throughout the world for its efficiency and economy. Though its advent in India is very new, extensive studies have already been made by several Governmental authorities and Central Public Health Engineering Research Institute and consequently ISI has laid down standards (IS:4985-1268) for rigid PVC pipes for protected water supply in India.
