An impact device for a drill string has a pipe with a variable length and a longitudinal extension, which has a first pipe element and a second pipe element that can be moved in the direction of the longitudinal extension relative to the first pipe element, which second pipe element is accommodated in the first pipe element. An electrical line runs from the first pipe element to the second pipe element, which line is connected to the first pipe element and the second pipe element and is wound coil-like in a central section around the second pipe element. A coil-like groove is arranged on the first pipe element and/or on the second pipe element, in which groove lies an area of the central section of the line.

Impact device for a drill string

Installation kit for hollow rods of a pipe string, in particular a drill string, with a first end and a second end, which are connected to one another by at least one connecting line. One of the two ends is arranged in a pin of the hollow rod, and the other end is arranged in a box of the hollow rod. A seal is arranged on the first end and/or on the second end, where the first end of an installation kit that is to be connected is sealed relative to the second end, and a sealing element that seals the respective end relative to the pin or the box is arranged on the peripheral surface of each end.

Installation kit, hollow rod, drill string and a method for producing or reworking a hollow rod of a drill string

A device for transmitting data and/or power from a rotating part, for example a pipe handler, to a non-rotating part, for example a top drive, of a drilling rig or a workover rig has at least one slip ring with at least one sliding contact in contact therewith. The device includes a first ring and a second ring. The first ring and the second ring delimit a closed area. The slip ring(s) and the sliding contact(s) is/are arranged within the closed area.

Device for transferring data and/or power in a derrick or in a workover rig

A drill pipe, particularly for a drill string, having an outer and an inner pipe (), a female connector () with an internal thread at one end of the drill pipe (), and a male connector () with an external thread at the end opposite from the female connector (), wherein the inner pipe () is arranged substantially concentrically in the outer pipe () and the drill pipe () has a center region () with an internal diameter. The outer pipe () has an inwardly thickened wall portion at an end region () on the male connector side, having a smaller internal diameter than the internal diameter of the center region (), and the internal diameter of the outer pipe () remains substantially the same at an end region () on the female connector side in relation to the internal diameter of the center region ().

Drill pipe

A drill pipe (), particularly for a drill string, has at least one electrical conductor () and an inner pipe () which is arranged inside the drill pipe (). The drill pipe () and the inner pipe () are spaced at a distance to one another in sections, wherein the drill pipe () and inner pipe () bound a hollow space (). At least one electrical conductor () is arranged on one outer side of the inner pipe.

A device for connecting at least one electrical data and/or supply line to electrical sockets of a wired drill pipe is disclosed. One inventive aspect of the device comprises: a collet blocking plug axially insertable into and removable from a receiver end of the drill pipe and at least one collet. The collet is configured to be interlocked with the drill pipe in a locking position and be released from the drill pipe in a release position. The collet is axially displaceable from the collet blocking plug between the locking position and the release position. The collet blocking plug is axially insertable into and removable from a receiver end of the drill pipe.
