PLASTICS PIPING: Survey of Properties and Applications in the Prevention of Corrosion

During the past few years the use of plastics piping has increased manyfold, although when compared with the established metallic tubes and pipes its proportion of the market is still relatively insignificant. Several factors, however, are likely to advance the use of plastics piping; these include improvements in the performance of the polymers available, improvements in pipe fabrication and user recognition of the advantages of these products. A further important consideration is that the future economic trends are likely to favour plastics in two ways. Firstly, the general price trend of metals is upwards, while in contrast the increasing production of plastics and improved control of fabrication processes are tending to reduce the price of plastics.
