Abstract

1332461 Tube expanding FOSTER WHEELER JOHN BROWN BOILERS Ltd 19 April 1971 [3 March 1970] 10197/70 Headings B3J and B3Q A tube expander comprises a stem 12 for insertion in the tube 102 and a sleeve 16 expansible by hydraulic fluid supplied along the stem, seals 36, 38, 40, 42 preventing escape of the fluid and parts 20, 22 of the stem preventing expansion of the ends of the sleeve 16. As shown, the sleeve 16 is of polyurethane and is secured by nuts 20, 22 on the stem, a nozzle-section of the stem being clamped by a screw 24. Compressedair acting on a piston 46 operates a plunger 50 to supply the hydraulic fluid from a reservoir 62. The expander is located by a stop 101 on the nut 20 and a safety device prevents expansion of the sleeve if the expander is out of a tube. The safety device includes a rod 90 moved endwise by a tube plate 100 or the expander is inserted in a tube. A lever 94 turned by the rod allows a spring-pressed valve 36 to close, sealing an exhaust passage 84.
