Unplasticized PVC pipes today need no introduction being one of the most ubiquitous piping systems, which are cost effective and improve the reliability of pipeline installations. They can be fabricated to close dimensional tolerances, are light without being weak, rigid without being brittle and cheaper per unit volume when compared with any other piping material. The principle reason for the great economy of uPVC pipe is not so much their cost per meter as delivered at site but the dramatic reduction in installation cost which can be achieved by intelligent exploitation of their being lightweight, their availability in longer lengths, their ease of joining and immunity from corrosion.
