摘要： A multilayered pressure vessel for handling hydrogen gas wherein the inner layer of the vessel is formed of a material resistant to hydrogen embrittlement. Individual sections of the inner layer and of the outer layers are welded together at circular joints. The welded joint for the inner layer is formed of a material which is resistant to hydrogen embrittlement, however, the weld material joining the outer layers is not resistant to hydrogen embrittlement. In constructing the vessel the welded joints securing the outer layers are displaced from and are out of contact with the welded joint securing the individual sections of the inner layer. Additionally, outlet holes extend from the outer surface of the vessel through each of the outer layers to the outer surface of the inner layer. The outlet holes are located in the area adjacent the welded joint securing the individual sections of the outer layers. Where the inner layer is secured to the outer layers as the final step in constructing the pressure vessel, a hole is bored through the innermost of the outer layers extending from the outer surface of the inner layer to the inner surface of the next outer layer. Further, where a solid flange member is secured at one or both ends of the vessel the welded joint securing the flange to the inner layer and the welded joint securing the flange to the outer layers are spaced from one another so that they are not in contact and outlet holes are provided in the region of the welded joint securing the flange to the outer layers. In the outlet holes hydrogen gas at the interface between the inner layer and the innermost of the outer layers is prevented from diffusing into the deposited metal and the outer layers of the vessel are protected from failures due to hydrogen embrittlement.

摘要： A welded joint construction is provided for large vessels, e.g., reaction vessels or tanks, having inner surfaces subject to hydrogen embrittlement and having a pair of multilayer laminated walls arranged to form a special weld joint. This joint is made by having a first metal cladded on at least a portion of the opposing edges of the weld joint and extending from the inner surface of the vessel subject to hydrogen embrittlement toward the opposite surface of the vessel. The first metal is (a) only slightly hardenable by the heat of welding, (b) resistant to hydrogen embrittlement, and (c) annealed prior to the welding of the joint. A quantity of the first metal weld is deposited between and joining the opposed faces of said first metal cladded on the edges of the weld joint. The welding of the joint is completed by depositing a second metal, which is only slightly hardenable by welding heat, between the opposed edges of the joint and extending from the first metal weld deposited therein toward the opposite outer surface of the vessel. At least one of the pair of walls which are joined consists of a plurality of layers of metal sheets (e.g., Cr-Mo or Mo steel) forming the exterior of the vessel, and an inner sheet forming the inner surface of the vessel which is made of steel rsistant to hydrogen embrittlement. Generally, the outer layer of sheets are only mechanically placed together without metallurgical joining, and also a plurality of vents are provided extending through these layers to the inner sheet''s outer surface. The method joins such walls without necessity of annealing, and is especially useful in large vessels which cannot be annealed after fabrication by welding.

摘要： 1,086,509. Welding by fusion; making pressure vessels; improving physical characteristics. MITSUBISHI JUKOGYO KABUSHIKI KAISHA. Dec. 1, 1964, No. 48885/64. Headings B3A, B3R and B3V. A pipe end is fixed in a hole in a wall of a laminated pressure vessel by welding. Layers 3, 5 of soft weld metal (i.e. metal softer than the metal of the laminations 1) are deposited on the periphery of the hole and around the pipe end 2 and are further softened by flame heating. The pipe end is secured in the hole by layers 5, 6 of soft weld metal and a flame or electric heater is applied to the interior of the pipe end to soften the surrounding parts. To further relieve the stresses in the weld zone the pipe end 2 is expanded by a tube expander. In a modification, the laminations are joined by a weld deposit and after heating to red-heat the zone surrounding the hole is permanently deformed outwardly by a jack located inside the vessel. The pipe end is then welded in the hole.

摘要： The apparatus is for bending a steel plate into any configuration having a compound curved surface. An upper punch group consists of at least three rows of punches aligning widthwise of the plate, disposed above it and adapted to form a curved surface for shaping the plate. A lower punch group consists of at least three rows of punches aligning widthwise of the steel plate and under it. The upper punch group is disposed so that the punches are individually adjustable in height, and the respective punch rows in the rows of punches can be arbitrarily preset in position w.r.t. the relative heights of the rows and the distances between the rows, as is the lower punch group.
