摘要: A pipe connection is formed in a tube plate (10) with a tube (12) of plastically deformable material which is inserted into a hole (14) in the tube plate. An annular seat (16) is provided in the wall of the hole (14). A sealing ring (18) of deformable material is placed between the seat (16) and the tube (12) in a gap formed as a result of constricting the tube (12) on its section. The tube is then expanded on its section (13) within the tube plate (10) resulting in metal to metal contact between the tube and tube plate. Expansion on the section (h1) results in the seat (16) becoming closed by an outward bent rim (20) of the tube (12), thereby compressing the sealing ring (18). The resultant pipe connection has an outer diameter (D1) on the section L1 in the hole (14) which is greater than that on the section (L) outside the hole (14).

摘要: A jet condenser of the type comprising a water chamber in a mixing chamber (24) and an after-cooler (52), wherein the water chamber is subdivided in a narrower upper water chamber portion (38a) and a broader lower water chamber portion (38b). The after-cooler (52) is fixed at the junction (66) of both water chamber portions (38a, 38b). Cooling water is injected into the mixing chamber (24) by nozzles (40) of the upper water chamber portion (38a) where it flows in vertical direction. By the reduced width of the upper water chamber portion (38a) flow resistance of steam flow in the mixing chamber (24) and, thereby, undesired subcooling is substantially diminished.
