ABSTRACT:
Breaks in the lining of a protectively lined reactor vessel are repaired without introducing unwanted electrical paths through the vessel. Specifically, the breaks are repaired using a plug comprising an insulated anchor stud anchored into the portion of the metal support wall underlying the break; a sealing gasket disposed on the portion of the protective lining surrounding the break; a washer disposed outside the sealing gasket; and a clamping arrangement mechanically coupling the washer and the anchor stud for clamping the gasket onto the protective lining throughout a path surrounding the break. In preferred embodiments, the insulating stud is a threaded cylindrical stud anchored into the wall by threading into a correspondingly threaded aperture, the sealing gasket is a corrosion-resistant, insulating plastic material such as a fluorocarbon, the washer is concave with respect to the gasket and filled with insulating cement, and the clamping arrangement is either a nut threadedly engaged to the insulating stud or a nut in combination with a second stud attached to the first. Reactor vessels using such repair plugs can utilize dip tubes of dissimilar metal without premature deterioration.
