SMOOTH, LIGHT, FEW JOINTS - PLUSES FOR UPVC. USE OF UPVC FOR UNDERGROUND PIPES
The advantages of unplasticised polyvinyl chloride (upvc) as a pipe material are described. These include the provision of a flexible system of pipes, fittings and joints which can absorb vibration and movement without fracture or joint failure. They are made in diameters that are interchangeable on a world-wide basis and being light can be handled easily. Smooth internal bores and infrequent joints result in reduced turbulence and the possibilities of blockage are reduced to a minimum. The availability of injection moulded specialist fittings has led to the position of a wide choice of means of access to drains and sewers. These factors have led to an increase in use of upvc in the building drainage market and further developments in engineering applications are expected to lead to their popularity in other fields. When upvc pipes were introduced a very conservative approach was adopted with regard to bedding and backfilling but it has since been demonstrated that this was overcautious and that most as-dug material will support the system. The next development expected is the use of extruded upvc strip helically wound on site to form pipes of whatever diameter required. (TRRL)
