摘要： Seal for tubular heat exchanger comprising groove (11) with an inner edge (404); tongue (401) of the diaphragm (13) having front face (402) extending in the radial direction and inner edge (403) parallel to the axis of the channel; the face (402) extending beyond the radial width of the groove (11) in inward direction and overlapping the face of the shoulder of the channel in which the groove (11) being provided. The tongue (401) of the diaphragm (13) being thus kept away from entering the groove (11); the diaphragm having flexibility to permit deflection of the tongue, the tongue of the diaphragm being loaded from outer side by the internal compression ring (9), the said internal compression ring (9) being loaded in turn by the threaded push bolts/rods (10) being fitted in the threaded holes on periphery of the threaded lock ring (2). This load is ultimately transferred to the joint between the gasket (7) and face (402) to achieve leak-proof joint.

摘要： Sealing arrangement for an internal tubesheet(4) for tubular heat exchangers comprising, a gasket (21) fitted between a shoulder (51) and a tubesheet (4), the gasket (21) being made of spiral wound construction but without any metallic rings and without any locating groove in the adjoining components. On the outer side of the tubesheet (4), a channel box (22) is provided with its inner face resting on a shoulder provided on an outer diameter of the tubesheet (4) while the outer face of the channel box (22) is reduced in diameter and arranged to align with the centerline of the push bolts (13), the outer face of the channel box (22) resting against and attached to an annular ring (12) and the push bolts (13) being provided in threaded holes that reach up to the outer face of an internal flange (24). The push bolts (13),when tightened, load the annular ring (12), which in turn loads the gasketed joint through the channel box (22) and the tubesheet (4).
