Abstract Use of glass reinforced epoxy disposal well tubing and line pipe in a chlor-alkali plant is described. Tubing was used in a well disposing of an average 275 gpm of corrosive wastes at about 120 F maximum including varying concentrations and proportions of hydrochloric, acetic, sulfuric and other acids, sodium hydroxide, sodium chloride, sodium hypochlorite, benzene, chloroform, carbon tetrachloride and other corrosives. Line pipe was used to handle various concentrations of acids and fume scrubbing liquids at temperatures from 60 to 200 F. Some difficulties with tubing were reported, attributed to improper joint design, variations in curing and variations in epoxy formulation. Line pipe failures were found to result from inadequate mechanical support and defective jointing, among other probable causes. Author concludes the glass reinforced epoxy materials are satisfactory under conditions prevailing in his plant where other materials have failed. Some precautions concerning selection are given. 6...
