The many technologies associated with the production, installation and uses of plastics pipes systems increase in their sophistication and diversity This paper selects and reviews changes that have and are taking place with polyvinyl chloride (PVC) and polyethylene (PE) pressure pipe systems designed for canying potable water, effluent and fuel gas. Changes in installation technologies are of equal importance but are outside the scope of this paper. The topics covered in this review are developments in PE and PVC materials, improvements in the production of PVC and PE pipes and fittings, changes in pipe jointing , and methods to improve the strength of plastics pipes. The author is seeking, for gas and water utility engineers, to paint the bigger picture of some of the performance changes that have and are taking place in the technologies associated with the PVC and PE pipe industries.
