Abstract

1353240 Repairing ruptured tubes FOSTER WHEELER CORP 14 Sept 1971 [14 Sept 1970] 42826/71 Headings F2P and F2G A tube 16 having a hole therein is repaired by enlarging the hole to form a window 30 and inserting a sealing device through the window. The sealing device comprises a pipe having an axially movable collar at each end. A respective sealing gasket is disposed adjacent each collar on the side nearest the ends of the pipe, and a respective ring is placed adjacent each gasket. Axial movement of the collars compresses the gaskets against the rings thus causing them to radially expand to grip the tube walls beyond the opening. As shown the collars and rings are screwed on to screw threaded portions of the pipe, and the collars are provided with sockets 54 to take a thomas bar or the like. In practice the sealing device is inserted by sliding one end into the enlarged opening until the other end may be inserted in the opening and then moving the sealing device back until both sealing gaskets bear on sound parts of the tube wall. The tube 16 may be one of a plurality of parallel tubes interconnected by longitudinal ribs to form a furnace wall.
