Abstract: A method for forming a conduit with a radial flange for forming part of a beaded coupling by: positioning a conduit blank in a forming die, wherein the forming die defines a radially extending recess; inserting a forming post in the conduit blank to define an annular space therebetween; inserting a flexible material in the annular space between the post and the conduit; placing a sleeve in a bearing relationship with the flexible material; compressing the flexible material between the post and the sleeve to force the flexible material against the conduit to expand the conduit outward into engagement with the radially extending recess in the forming die to form an annular flange; and releasing compression on the flexible material.

Abstract: A process and a device produces an assembly linkage on a hollow profile which is shaped for the installation of the assembly part by internal high-pressure remodeling. In order to achieve the shaping of an assembly linkage in a component space-saving, for a subsequent assembly correctly positioned, and with regard to its contour exactly fitted to the assembly part, in simple manner and even with high degrees of remodeling in a secure process, the hollow profile, under internal pressure, which is smaller than the remodeling pressure, is indented at the place of the to-be-produced assembly linkage by a die and by forming a rough contour. Afterward, while the die remains in this indenting position, a fluid high pressure is created in the hollow profile. Thereby, the hollow profile sides surrounding the die are molded to the external contour of the die, and that after releasing the fluid high pressure and the subsequent removal of the die, the finished trough-shaped assembly linkage is released.

Abstract: A flangeless pipe joint including lined pipes with the end section of the outer pipe spaced radially outwardly from the liner and insulating material filling the space between the end sections of pipe and liners. The ends of the liners are sealed to each other and the outer pipe ends are joined by an outer sleeve.

Abstract: An apparatus and process for selectively expanding the wall of a tube by compression and subsequent radial expansion of one or more elastomeric bars lodged within longitudinal slots of a bushing positioned inside the tube. Expansion of the elastomeric bars against the inner surface of the tube results in expansion of the tube wall at intermittent locations about the circumference of the tube.

Abstract: A tubular can body comprising a radially expanded central portion, a neck at each end of the central portion, and a radially extending flange adjacent each neck at the ends of the tubular member. A tubular, elastomeric member is positioned within a die-contained can body and is pressurized to mold the can body to the shape of the die. The operation forms a radially expanded can body, necks the can body adjacent the radially expanded portion, and flanges the ends of the body in a single operation. A tapered elastomeric mandrel may be utilized in place of the tubular mandrel, obviating the necessity of lubricating the mandrel and allowing the body to be axially extended so that the material from which the can is formed is altered in cross section both radially and axially. A structural groove, suitably positioned in the mandrel surface allows flanging to be effected at the upper end of the can body without damage to the mandrel. Alternatively, an expandable member may be substituted in place of either the tubular or tapered mandrel to form the can body through use of hydraulic pressure.

Abstract translation: 包括径向膨胀的中心部分的管状罐体，在中心部分的每个端部处的颈部以及在管状部件的端部处与每个颈部相邻的径向延伸的凸缘。 管状的弹性体构件定位在一个装有模具的罐体内，并被加压以将罐体模制成模具的形状。 操作形成径向扩张的罐体，颈部靠近径向扩张部分的罐体，并且在一个操作中对主体的端部进行凸缘。 可以使用锥形弹性体心轴来代替管状心轴，从而避免了润滑心轴的需要，并允许主体被轴向延伸，使得形成罐的材料在径向和轴向方面的横截面都改变。 适当地定位在心轴表面中的结构凹槽允许在罐体的上端实现凸缘，而不损坏心轴。 替代地，可膨胀构件可以代替管状或锥形心轴，以通过使用液压来形成罐体。
