Rigid PVC Pipes-The Piping Material of Today

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.
