Abstract

Polyolefin pipes are in use since few decades in numerous applications. Polyolefins have numerous advantages vis-à-vis its competing polymer material the PVC. However PVC still continue to be the most preferred pipe making polymer all over the world. One of the main reasons which hinder growth of polyolefins in pipe applications is difficulty in joining/bonding of polyolefin pipes. To overcome this shortcoming of polyolefin pipes and pipe-fittings, we have devised a polyolefin pipe and pipe-fitting system which can be easily, economically and satisfactorily joined / bonded like PVC pipes and pipe-fittings. The scheme is to coextrude polyolefin pipe and coinjection mould polyolefin pipe- fitting in multilayers, where the outermost layer of pipe and innermost layer of pipe-fitting shall be made of material which is amenable (suitable) to solvent welding/bonding and/or adhesive bonding. And when solvent is applied to the outer surface of pipe and inner surface of pipe-fitting, the two surfaces shall become pliable and on mating, the surface shall weld / fuse/bond, thus bonding pipe to the pipe-fitting. Similarly pipe and pipe-fitting can be adhesive bonded.
