Abstract: An electric resistance welded steel pipe having excellent formability and torsional fatigue resistance and a method for manufacturing the same. The electric resistance welded steel pipe includes a seam region and a base metal region, the seam region having a range of ±10 degrees in a pipe circumferential direction with respect to an electric resistance welded seam formed in a pipe longitudinal direction, the base metal region being a region other than the seam region. The electric resistance welded steel pipe has an r-value in the pipe longitudinal direction of 1.0 or greater, H (mm) and W (mm) satisfy a specified formula, and Ts(MAX) (mm) and Tb(Ave) (mm) satisfy a specified formula.

Abstract: A method and device provides for alternately cutting off material by back-and-forth movement of multiple vehicles. Specifically, the device is a cut-off machine for alternately cutting off material by back-and-forth movement of multiple vehicles. The cut-off machine is at least provided with two cutter vehicles, wherein these vehicles are installed on tracks parallel to material. The tracks are arranged around the material side by side. Each vehicle moves back and forth in accordance with a set sequence. Cutters on the vehicles alternately cut off the material in accordance by a set length. The larger the number of vehicles, the longer the possible stroke of each vehicle can be, such that the cutters have more time to cut off the material. Accordingly, the cut-off machine can be adapted to higher material forming speeds in a production line.

Abstract: A conveying apparatus with a first conveyor and a second conveyor is used a the welding apparatus and a welding method for container bodies and in particular can bodies between which conveyors the object to be welded is handed over. A control unit determines the take over position and/or the conveying travel of the second conveyor and controls the conveyors accordingly, so that the take over occurs at the determined position and/or with the determined conveying travel of the second conveyor. This allows an easy and swift changing of the welding apparatus to different sizes of the objects to be welded.

Abstract: A method for manufacturing tubes, in particular for heat exchangers, composed of endless ribbons on a roller mill, wherein the tubes are composed of at least two ribbons which are subjected to a shaping process on the roller mill, wherein perforations or predetermined break points are introduced into the ribbons at predetermined locations, wherein a step of making the perforations in the ribbons is carried out, after which the ribbons are combined to form the tube and after which individual tubes are separated off at the predetermined locations. The formation of the perforations or the predetermined break points in at least one of the two ribbons is performed within or at the end of the shaping process of the corresponding ribbon so that some of the pairs of rollers do not require a drive.

Abstract: Metallic tube, pipe and conduit are made in a continuous process that includes a zinc galvanization stage, a first passivation stage, a second passivation stage and a third passivation stage. A colorant is added to the tube, pipe or conduit during the continuous manufacturing process, and the colorant imparts the appearance of a color, such as red. The continuous movement of the tube, pipe or conduit is not halted during normal operation of the tube, pipe or conduit manufacturing and coloring process.
