Abstract: The method is used to produce connecting elements (1). The connecting elements (1) are intended for coupling functional elements for applications in the field of oil drilling technology. The connecting element comprises two end pieces (2, 3) and at least one spacer (4) connecting the end pieces to each other. At least one spacer (4) is connected to at least one of the end pieces (2, 3) by pressure welding.

Abstract: The handling apparatus is used for positioning and holding of drill pipes. At least, a handling apparatus for the drill pipes is so arranged that it can be positioned both horizontally and vertically and it is equipped with a controllable clamping apparatus for the drill pipes. In the vicinity of the holding apparatus, a centering apparatus is arranged for the drill pipe to be held.

Abstract: A device for vertically holding pipes, which includes a base element in the form of a segment of a cylinder, a door element pivotably connected to the base element by at least one pivot joint, and a fastener assembly mounted opposite the pivot joint. The fastener assembly has a pivotable catch with a locking profile that, when in the locked state, grips a locking pin from behind. A safety pin and a safety plate are located in the area of the pivotable catch, and, depending on its position, the safety plate releases or closes at least one opening for the safety pin.

Abstract: The invention relates to a device for vertically holding pipes, comprising a base element in the form of a cylinder segment and at least one door-type access element which is pivotally connected to the base element by means of at least one pivot joint. A closure (13) is arranged opposite the pivot joint. Said closure has a pivotable lock which engages, when locked, with a latch profile (15) behind a locking pin (16). A securing pin (24) and a securing plate (23) are arranged in the area of the pivotable lock. The securing plate, depending on the position, releases at least one recess for the securing pin or closes the same.

Abstract: The invention relates to a device for handling pipes, comprising a clamping device (2) carried by a handle (1). The clamping device is configured from at least one spacer element (4) which is pivotally connected to the handle and a clamping jaw support (5) which is pivotally connected to the spacer element. The spacer element and the clamping jaw support are interconnected by an adjustable coupling (15). Said coupling provides at least two different pipe width dimensions for a handling space.

Abstract: An apparatus for vertically supporting pipes in oil production rigs. The apparatus includes an outer frame and a centering device. In the area of an inner side of the outer frame, at least one wedge device is provided for clamping the pipe. The outer frame is connected to the centering device so as to be vertically aligned and facing upwardly. A wedge device may additionally include a positioning device and a carrier provided with at least one wedge.

Abstract: A device for connecting and disconnecting pipe segments of drill pipes, includes an adjustable retaining element in the form of a collar. For firmly holding the pipe segments introduced into the collar, segments acting as clamping jaws are used for retention. The clamping jaws can be adjusted vertically by servo elements for reducing the receiving diameter. The segments have a conical outside contour and a conical guide on the collar and a corresponding conical guide is provided on the collar, so that, when the segments are vertically displaced, the receiving diameter is reduced.

Abstract: An elevator mechanism for use on drilling rigs for hoisting and lowering different sizes and types of pipe. At least two elevator frame sections are interconnected in relative moveable relation for movement between an open position for receiving a section of pipe and a closed position clamping about the pipe. At least two pipe clamping inserts being received in interengaged relation by respective elevator frame sections in a manner resisting upward and downward movement relative to the frame sections. The pipe clamping inserts are mechanically interengaged with the elevator sections to prevent inadvertent disassembly downward and are releaseably locked to secure the inserts against rotation relative to the frame sections. For assembly and disassembly of the inserts relative to the frame sections, the inserts, when unlocked, are rotated for engagement or separation of the mechanically interengaged relation.
