Patent number: 10099319Abstract: A device for connecting the ends of pipes, which are aligned, tack-welded and made of steel, by an orbital welding process using a welding joint formed by the pipe ends and using tools which can be orbitally moved about the welding joint for welding and checking the seam. The device includes guide base plates placed on both sides at each pipe end in the region of the welding joint and rigidly clamped to the pipe ends. The guide base plates centrally have a circular recess with a radial opening for the feed-through of the pipes to be welded. The guide base plates include clamping elements rigidly connected to each guide base plate face facing away from the welding joint, and a frame for receiving the welding and checking tools, the frame rotatably mounted between the guide base plates and centrally pivotal about the pipe ends by at least 360°.Type: GrantFiled: March 26, 2013Date of Patent: October 16, 2018Assignee: Salzgitter Mannesmann Line Pipe GmbHInventors: Hans-Jürgen Kocks, Jörn Winkels, Steffen Keitel, Jan Neubert, Sebastian Rude

Patent number: 9982410Abstract: The foundation structure of an offshore structure, for example of an offshore wind energy system, is composed of steel tubes sheathed by an extruded layer made of a polyamide moulding composition. This simultaneously ensures both good protection from corrosion and good protection from mechanical effects, giving the foundation structure markedly prolonged lifetime.Type: GrantFiled: April 10, 2012Date of Patent: May 29, 2018Assignees: Evonik Degussa GmbH, Salzgitter Mannesmann Line Pipe GmbHInventors: Markus Hartmann, Claudia Behrens, Reinhard Beuth, Joern Winkels, Hans-Juergen Kocks, Konrad Thannbichler

Patent number: 9574700Abstract: A pipeline laid trenchlessly and/or without a sand bed is produced using a metallic conduit which is encased with an extruded layer of a polyamide molding material. In this way, the durability of the outer shell required for trenchless laying techniques without a sand bed is ensured.Type: GrantFiled: August 27, 2008Date of Patent: February 21, 2017Assignees: Evonik Degussa GmbH, Salzgitter Mannesmann Line Pipe GmbHInventors: Andreas Dowe, Rainer Goering, Martin Risthaus, Klaus Gahlmann, Reinhard Buessing, Hans-Juergen Kocks, Joern Winkels

Patent number: 9535040Abstract: The invention relates to a method for testing connections of metal workpieces to plastic compounds for cavities by means of ultrasound, wherein the plastic compound is arranged between the workpiece as an intermediate layer or is connected to the workpiece on one side and the cavity is located within the plastic compound, wherein the cavity is connected to the workpiece by means of a remaining plastic layer or plastic skin and wherein the plastic compound is exposed to ultrasonic signals of a certain test frequency and pulse length from the metal side of the workpiece by means of at least one ultrasonic probe, and in particular the ultrasonic signals reflected by flaws in the plastic compound are detected by the same or another ultrasonic probe and converted into electrical signals that can be evaluated and subjected to a threshold observation. The test frequency of the ultrasonic signals is set in a range of 1 to 10 MHz so that the attenuation of the sound is minimal after passing through the plastic skin.Type: GrantFiled: November 29, 2010Date of Patent: January 3, 2017Assignee: SALZGITTER MANNESMANN LINE PIPE GMBHInventors: Michael Kaack, Christian Kremer, Jörn Winkels, Holger Brauer

Patent number: 9134116Abstract: A two-dimensional light-section method for measuring the profile geometry of cylindrical bodies is disclosed. A fan-shaped laser line forming a light-section line on the surface of the body is imaged with at least one laser, and the laser radiation reflected from the surface of the body is captured by at least one area imaging camera, wherein the laser and the camera are arranged at a triangulation angle in a normal plane aligned with the cylinder axis. The profile geometry is then measured by pivoting the laser out of the normal plane about the cylinder axis. The angle with respect to the normal plane is selected such that the optical axis of the area imaging camera with respect to the surface of the cylinder is located within the glancing angle range of the reflected beams.Type: GrantFiled: February 2, 2011Date of Patent: September 15, 2015Assignee: SALZGITTER MANNESMANN LINE PIPE GMBHInventors: Gerd-Joachim Deppe, Norbert Schönartz, Holger Brauer, Jörn Winkels

Publication number: 20150060436Abstract: A device is disclosed for connecting the ends of pipes, which are already aligned and tack-welded and which are made of steel in particular, by means of an orbital welding process using a welding joint which is formed by the pipe ends and using tools which can be orbitally moved about the welding joint for welding and checking the welding seam. The device includes guide base plates which can be placed on both sides at each pipe end in the region of the welding point and which can be rigidly clamped to said pipe ends. The guide base plates centrally have a circular recess with a radial opening for the feed-through of the pipes to be welded and for centrally receiving said pipes in the recess.Type: ApplicationFiled: March 26, 2013Publication date: March 5, 2015Inventors: Hans-Jürgen Kocks, Jörn Winkels, Steffen Keitel, Jan Neubert, Sebastian Rude

Patent number: 6887020Abstract: A device for deburring the inside of a longitudinally seam-welded pipe includes a retention arm secured outside the pipe in the area of the pipe that is not yet closed and having an end zone which is located behind the welding spot. Arranged on the retention arm is a frame part which is tiltable in longitudinal direction of the pipe about a tilt axis and provided with a scraping tool. The tilt axis of the frame part is hereby located, as viewed in advancing direction, behind the scraping point at the end of the frame part. An adjustment mechanism is provided on the forward end of the frame part for adjusting the tilt angle.Type: GrantFiled: February 17, 2004Date of Patent: May 3, 2005Assignee: Mannesmannröhren-Werke AGInventors: Jörn Winkels, Bernd Engler
