A method and device for moving racked tubulars, such as pipe and casing joints on pipe racks at oil and gas well sites. The pipe moving tool comprises a wheel assembly with a long straight handle. The wheels fit inside the pipe, which is then moved by simply pushing or pulling the handle forward or backward, as needed. Several wheel assemblies of different diameters may be used interchangeably with a single handle. An extension handle also may be included. The use of this tool makes moving the pipe safer as the worker's hands are not exposed to injury. Additionally, the handle on the tool makes it possible to easily and more safely reach and move shorter pipes racked above or below longer pipes in a multi-level pipe rack; it is not necessary for the worker to lean over or under the longer pipes.

A method for storing cardboard tubes (2) in a storing unit according to the present invention comprising the following steps: providing a storage unit with an input section for the tubes (2), a storage section (AC) comprising a plurality of storing planes (13), an output section for the tubes (2), transfer means (3) for transferring the tubes (2) from the input section to the storage section, and discharge means for conveying the tubes (2) from the storing section to the output section; providing a plurality of cardboard tubes (2) in the input section (E) of said storage unit; transferring the tubes (2) from the input section of the storage unit to the storage section; storing a plurality of tubes (2) in said storage section (AC); transferring the tubes (2) from said storage section (AC) to said output section. The step of transferring the tubes (2) from said input section to said storage section involves more tubes (2) simultaneously, whereby a plurality of tubes (2) are transferred from said input section simultaneously on a plurality of storing planes (13) of the storage section (AC).

Device for controlling a flow of cardboard tubular cores (1) adapted to produce logs of paper material and intended to be stored in a collection point (2) placed downstream of the same device, comprising more conveyors (5; 7) each of which is adapted for carrying the said tubular cores (1) up to the entry point (6D) of a respective guide channel (6) having an entry point (6D) and an exit point (6F), interception means (8) adapted for intercepting the tubular cores (1), said interception means being arranged and acting on each of said channels (6) to adjust the flow of the tubular cores through the respective exit points (6F), and programmable means (UE) adapted for activating and deactivating said interception means (8). The interception means (8) are adapted to selectively form two nips (N1, N2) inside the guide channel (6), the nips (N1, N2) being selectively formed at a predetermined distance from each other.

Disclosed herein are systems, methods, and devices for transporting substrates. A transport device may include a plurality of rotational bodies, where each rotational body is rotatably attached for transporting a rod-shaped workpiece. The transport device may include a rotational excitation element configured to excite rotation of the workpiece when it is supported on one of the plurality of rotational bodies.

A continuous pipe feeder machine which avoids clamping against welded joints of a pipe is provided. The continuous pipe feeder machine is especially suitable for use in pipeline and tunnel construction. The system includes soft pads for moving a pipe. The soft pads of the machine for moving the pipe are located at strategic locations on the machine so that a pipe fed into the machine gets moved without the pads compressing and damaging the welded joints of the pipe.

The present invention relates to a system and method for torquing tubular goods at an inland facility to form tubular assemblies, conveying the tubular assemblies, and transporting the tubular assemblies to well construction sites.

The present application pertains to the field of pipe transport and relates to a clamping and placing device for clamping and releasing a pipe. The clamping and placing device comprises a bearing mechanism and a clamping and placing mechanism. The bearing mechanism includes a bearing seat provided with a bearing area. The clamping and placing mechanism includes a first clamping member, a second clamping member, a first pushing member, a first rotating member, and a second rotating member. The second clamping member and the first clamping member are configured to clamp the pipe in the bearing area. The first pushing member is configured to rotate through the bearing area to push the pipe out of the bearing area. The first rotating member is connected to the first pushing member and is configured to drive the first pushing member to rotate. The clamping and placing device facilitates rapid pipe release.

An apparatus for transferring a tube includes a first conveyor where a tube is transferred, a second conveyor located at a lower level than the first conveyor, and a sliding structure including a guiding body positioned between the first conveyor and the second conveyor and guiding the tube provided in the first conveyor so that the tube is slid down and a controller configured to control so that the tube that is slid down is selectively provided to the second conveyor.

A vacuum lifting arrangement having a lifting tube and a suction foot for engaging with an object to be lifted, is disclosed, said vacuum lifting arrangement having a pneumatic valve fluidly connected to ambient air, wherein, during operation of the vacuum lifting arrangement, when an object is not engaged with the suction foot, an air-flow from the suction foot into the lifting tube is prevented by the valve which is in a closed position, and, upon generation in the suction foot of a pressure lower than the surrounding pressure, e.g. due to engagement with an object to be lifted, the valve will be in an open position, allowing an-air flow from the suction foot into the lifting tube. A lifting tube comprising a pneumatic valve for use in the lifting arrangement is also disclosed.
