A method for producing open-seam pipes from flat metal products, in particular sheet metal, includes a plurality of individual bending steps using at least one bending tool and at least one externally located lower tool. A plurality of positions of individual bending steps and the insertion depth of the bending tool are calculated in advance. Based thereon the flat metal product is then shaped step-by-step to form the open-seam pipe. After each of the bending steps, a target/actual comparison of the distance between two edges and/or between one of the two edges and the axial center line of the flat metal product is carried out. In case of a deviation, a correction value for the subsequent bending step is determined using a correction algorithm so as then to adapt the insertion depth for the bending tool.

Method for producing open-seam pipes

A metal pipe and a system of pipes, and a method of producing the same. The pipe is for conveying oil and gas. The pipe includes a metal coating in a transition region. The metal coating of the transition region obviates a subsequent coating of the inner surface of the transition region after connecting two pipes using a welding process in order to form a pipeline.

A method for producing open-seam pipes from sheet metal panels, in particular thick sheet metal panels. A sheet metal panel, having bending edges on the long sides thereof, is fed to a pipe forming press where the sheet metal panel is formed, lying on a lower tool having of two supporting elements which are horizontally spaced apart from each other, by an upper tool, which can be raised and lowered, by application of a bending force, progressively into an open-seam pipe having bending edges on opposite long sides with a gap for later longitudinal seam welding. In order that the sheet metal panel can be easily, progressively formed or shaped from the start, at least the bending sections immediately adjacent on the bending edges of the sheet metal panel are each formed from the outside to the inside, deviating from a numerically ascending bending step sequence in a pilgering process sequence.

The invention relates to a method and a device for optically measuring the interior of a seamless pipe which is manufactured by rolling or of a pipe which is welded with a longitudinal seam and is manufactured from sheet-metal plates shaped to form half-shells or from a shaped sheet-metal plate or from a metal strip which is unwound from a coil, comprising a sensor means () which emits a laser beam () in the interior of the pipe (). In such a method and device, an internal measurement of seamless pipes or pipes which are welded with a longitudinal seam is to be provided with which it is easily possible to determine and model precisely the ovalness and straightness of the pipe () in a station. For this purpose there is provision that the sensor means () is moved horizontally through the pipe (), wherein the internal contour () of the pipe () is measured in that a laser tracker () which is positioned at the end of the travel path follows, with its laser beam (), the respective position of the sensor means () in the space of the pipe () and senses deviations of the sensor means () from straightness.

Method and device for optically measuring the interior of a pipe

An apparatus for three-dimensionally imaging a pipe centered on and extending along an axis has supports for supporting the pipe by engagement with only an inside surface of the pipe such that an outer surface of the pipe is entirely exposed. A scanner is spacedly juxtaposed with and around the outer surface of the pipe. The scanner and the pipe can be relatively axially displaced such that the scanner passes along a full length of the pipe for scanning of the entire outer surface.
