EXECUTIVE SUMMARY
' Phase one of the Vinyl Institute's research program "Evaluation of the.-Permeation of Organic Solvents through Gasketed Jointed and Unjointed Poly(vinyl chloride). Asbestos Cement and Ductile Iron Water Pipes", has been completed. Phase, one involved the exposure of commercially available four-inch water pipe joints to three neat-organic solvent environments, toluene, hexane, and 1,1,1-trichloroethane, for a period of six weeks. Each pipe specimen contained demineralized water under a pressure of 40 psig and throughout the six-week exposure period, samples of water were removed from each pipe and analyzed for traces of the appropriate organic liquid.
The objective of this study was to study when and how permeation of selected solvents occurs through the jointed and unjointed pipes and to develop a hypothesis for the mechanism of permeation. The test results indicate that the mechanism for fastest breakthrough (permeation) is through the gasketing material. The unjointed pipe showed slower permeation or no permeation com pared to the jointed pipe-. When permeation did occur w.ith the jointed pipe, it happened much earlier than with the straight unjointed pipe. Another mechanism for breakthrough is based on the composition of the pipe. The more porous asbestos cement unjointed pipe showed earl-y permeation with toluene and 1,1,1trichloroethane and the unjointed PVC pipe swelled to permeation with toluene after day 37 of the 42-day test. These results are summarized in Table 1.
The initial work was performed under "worst case model" conditions. The breakthrough of neat solvents in the jointed test specimens indicates that the joints of all three materials are susceptible to permeation. The second phase of the program, exposure to aqueous solutions of the same organic sol vents, appears to be warranted in order to determine permeation under more realistic conditions. Consideration should be given in characterizing the rubber compounds used in the gaskets. Differences in the gaskets used with each type of pipe may explain the apparent differences in permeation, particu larly the hexane results.
