Abstract
An expansion-joint system (48) for forming a seal between a steam turbine and a condenser includes an expansion-joint belt (50, 51) having a width-wise cross-sectional shape with first and second knobs (62, 64) at respective first and second opposite ends (72, 74) of a thinner elongated web (70). The knobs are formed by an abrupt bulge (66, 68) on only a first opposite side, while each of knob portions (76) of a second opposite side of the belt, opposite the bulge, forms a substantially straight line with a lead-in portion (80) from the elongated web. The knob portion and the lead-in portion of the second side are parallel with a symmetrical center (57) of fabric layers (56) in the belt. In one embodiment the substantially straight line formed by the knob portion and lead-in portion of the second side continues over a distance of approximately at least twice the length of the bulge. Clamping mechanisms (52) for clamping onto the first and second knobs each includes a clamping element (84) to be attached to a wall and having and indentation for receiving the bulge, and a clamping bar (88) having a substantially flat surface for mating with the knob portion and lead-in portion of the…
