摘要： An apparatus for hydrostatic pressure testing of tubular products that enables short segments of the tubular product to be individually tested under conditions simulating a capped tube hydrostatic test. The apparatus includes a first seal bladder and gripper member assembly connected to a second seal bladder and gripper member assembly by a connecting member that allows relative axial movement between the two assemblies. A fluid outlet port is provided in the connecting member to introduce pressurized fluid into the short segment of the tubular product between the seal bladders of the two assemblies. Since the first seal bladder and gripper member assembly is axially movable relative to the second seal bladder and gripper member assembly, an axial stress as well as a hoop stress will be induced in the tubular product during testing.
摘要翻译： 用于管状产品的静水压力测试的装置，其能够在模拟封盖管静水压试验的条件下单独测试管状产品的短段。 该装置包括通过连接构件连接到第二密封囊和夹持器构件的第一密封囊和夹持构件组件，其允许两个组件之间的相对轴向移动。 流体出口端口设置在连接构件中以将加压流体引入到两个组件的密封囊之间的管状产品的短段中。 由于第一密封囊和夹具构件组件相对于第二密封囊和夹持构件组件可轴向移动，因此在测试期间将在管状产品中引起轴向应力以及环向应力。

摘要： A nuclear steam generator having anti-vibration bars for limiting the motion of spaced heat exchanging tubes is provided with a shim located between every n.sup.th tube where n is greater than 1. The shims have a thickness equal to n times the dimensional difference (x-y) of the distance x between a pair of tubes and the width y of an anti-vibration bar between the tubes. The shim is of channel-shape and is put in position by cutting and removing the wrap-around bars from the outside of the tube bundle, inserting and expanding a bladder to spread the pair of tubes in the bundle on opposite sides of an anti-vibration bar, moving the anti-vibration bar between the pair of tubes to one side of the opening created by the bladder, inserting a shim of modular links between the anti-vibration bar and one tube of the pair of tubes and repeating the bladder inserting, expanding and anti-vibration bar moving steps to insert shims at intervals n along the bundle. Thereafter, a new wrap-around bar is welded to the ends of the anti-vibration bars on the outside of the tube bundle.

摘要： A stamping device (28) having a stationary base assembly (76), a carriage assembly (52) mounted on the base assembly for stepwise horizontal movement in a first direction relative to the base assembly, and a marker assembly (34) mounted on the carriage assembly for stepwise horizontal movement in a second, perpendicular direction. The marker assembly includes a marking pin (30) vertically actuable by an air cylinder (42) for impacting the tube sheet (14) adjacent a preselected tube (16). A control system (124) sequentially activates stepping motors (60,66) and the air cylinder to produce a dot matrix character (114) on the tube sheet.

摘要： A radiation reducing door assembly comprises a mounting bracket having hinge means affixed thereto, said hinge means defining different axes of rotation for doors of at least two types, the doors being sized and shaped to overlie at least a portion of the opening with which the assembly is associated. The door assembly also includes means for rotatably coupling the removable doors to the hinge means whereby the mounted door is supported from said bracket and may be pivoted between open and closed positions.
