20130186864 | DEVICE FOR CONTINUOUSLY MANUFACTURING PIPES OF METAL - A device for continuously manufacturing pipes of metal, wherein the device includes a shaping unit ( | 07-25-2013 |
20130205858 | DEVICE FOR UNDULATING A PIPE CONSISTING OF METAL - A device for undulating a metal pipe having an undulation extending transversely of its longitudinal direction. The device has a ring-shaped undulating head drivable by a first electric motor and is rotatable about its axis in the operating position and a ring-shaped undulation disc, coupled to the ring-shaped undulating head, projects radially inwardly from the undulation head. The undulation disc is mounted in the undulation head so as to be adjustable in the radial direction. A support, coupled to the undulation head, is arranged so as to also be rotatable about the axis of the undulation head. An adjusting mechanism acting on the undulation disc is mounted on the undulation head. The adjusting mechanism serves for radially adjusting the undulation disc and is adjustable by the support. The support is connected to a second electric motor serving for rotating the support about the axis (A) of the undulation head. | 08-15-2013 |
20130313308 | DEVICE FOR TRANSVERSE SEAM WELDING - A device and a method for the positionally accurate arrangement of two material ends located opposite each other. The device includes two carriers with always one fixing device for each material end, wherein at least one of the two carriers is slidably guided relative to the second of the carriers, and at least the first carrier has a first adjusting member and a second adjusting member connected to the first adjusting member, wherein the adjusting members form a drive by means of which the first carrier is slidable against the second carrier. | 11-28-2013 |
20140091064 | METHOD OF WELDING BY MEANS OF A LASER - Method of welding edges which are placed against each other of at least one workpiece of metal by means of a laser is indicated, in which the areas of the workplace located at the edges are subjected to a pretreatment for increasing the absorption capacity of the light of the laser. For this purpose, initially color is sprayed or splashed onto the areas of the workpiece located at the edges, while avoiding any mechanical contact of the workpiece, by means of a device ( | 04-03-2014 |
20140305178 | DEVICE FOR UNDULATING A PIPE - A device for imparting an undulation to a smooth pipe ( | 10-16-2014 |
20150068020 | METHOD FOR PRODUCING MULTI-WALLED METALLIC TUBES - A method for producing a tube ( | 03-12-2015 |
20150068263 | METHOD AND DEVICE FOR MANUFACTURING A CORRUGATED METAL PIPE - A corrugating unit is used which presses a first corrugation into the pipe which is moved in its longitudinal direction through the corrugating device. The spacing between the wave peaks is subsequently reduced, for obtaining a second corrugation, by a clamping unit composed of two separately arranged clamping devices resting against the pipe. The pipe provided with a first corrugation is pressed continuously by the first clamping device against a fixed point realized by the second clamping device, which, in the position of operation, is arranged, in relation to the clamping device, in axial direction. behind the first clamping device. Both clamping devices are removed cyclically from the pipe and are moved back into a new position in the opposite direction of the direction of movement of the pipe and, in this new position, again rest in the two different areas against the pipe. | 03-12-2015 |
20150102088 | METHOD OF PRODUCING METALLIC COMPOSITE PIPES - A method is provided for producing a pipe from a band which has a layer of a first metal and a layer of a second metal, the layers being metallurgically bonded to one another over the entire length of the band. Along the two longitudinal edges of the band, the first metal is removed from the second metal in strips which run over the entire length of the band. The band is formed into the open-seam pipe with the first metal located on the outside, and the abutting edges of the layer of the second metal are welded to one another forming a pipe which is closed all the way round. In the region of the weld seam, a layer of the first metal is then deposited on the second metal to produce a pipe with a layer of the first metal which is closed all the way round. | 04-16-2015 |
