Rigid, unplasticized, polyvinyl chloride is one of several thermoplastic materials which can be made available on a reasonable, commercial basis in the form of pipe, as well as in other forms necessary for the assembly of a complete piping system.

These materials offer resistance to widely varying conditions of environment, light weight, relatively low cost, ease and economy of installation, self-insulating characteristics, minimum solid-deposit tendency, and low frictional losses. On the other hand, these materials have lower mechanical properties than most metals, and these properties are subject to wider variations as a function of temperature.

Of the thermoplastic piping materials reasonably available on a commercial basis, rigid, unplasticized, polyvinyl chloride appears to offer the best combination of engineering properties for application in the chemical process industry.

Based on a survey of the chemical process industry, it appears that rigid, unplasticized, polyvinyl chloride has given the greatest satisfaction where it has been used, and appears to have a greater growth potential than any of the other reasonably available thermoplastic materials for chemical process applications.
