    IPC: B21C37/12

    Abstract: The invention relates to a method and a system for manufacturing a carcass (1) for a flexible pipe. The carcass is provided by shaping and folding at least one metal strip (2) to form interlocking windings resulting in a tubular carcass extending along a carcass axis (8). A first force (F1) is then applied to at least a first region (9) of the carcass, the first force having a first force component parallel to the carcass axis, so that the pitch (P) of the windings is decreased to be within a first pitch value range. Subsequently, a second force (F2) is applied to at least a second region (10) of the carcass where the pitch of the windings is within the first pitch value range. The second force has a second force component parallel to the carcass axis and is applied so that the pitch of the windings is increased to be within a second pitch value range. The pitch within the second pitch value range is larger than the pitch within the first pitch value range.

    Abstract: The present invention provides an apparatus for manufacturing steel pipes by helically forming an elongated strip of metal. A novel pipe production apparatus is provided for helically forming a metal strip comprising a carriage for carrying a substantially planar metal strip in a feeding direction and a frame arranged adjacent to an end of the carriage supporting a metal curling device for receiving the metal strip, curling the metal strip and advancing the curled metal strip in a production direction that makes an angle with the feeding direction to form a pipe in the production direction. Also, a novel curling device for curling a metal strip and a novel roll for advancing a metal strip is disclosed.

    Abstract: Devices, systems, and methods are directed to formation of tubular structures, such as spirally formed structures, having spirally extending reinforcing material. In particular, tubular structures can be formed in a continuous process in which a first material is spiral formed along a first spiral and a second material is joined to the first material along a second spiral to reinforce the spirally formed first material. As compared to manual application of reinforcing material, such a continuous process can facilitate producing tubular structures at rates suitable for high- volume, commercial fabrication. Further, or instead, as compared to the use of circumferentially extending reinforcing material to support a spiral formed tube, reinforcing the spirally formed first material with a spiral of the second material may offer certain structural advantages, such as improved resistance to buckling.

    Abstract: A pipe cutting system (40) and method for cutting a helically wound steel pipe while the pipe is being moved in a direction (12) of its longitudinal axis uses a plasma torch (50) supported to be reciprocally movable parallel to the longitudinal axis and at an orientation relative to the pipe so that a plasma jet emitted by the plasma torch is directed upwardly toward the pipe. The plasma torch is arranged move at a speed that is synchronised with a speed at which the pipe is being moved in the direction of the longitudinal axis. The pipe is rotated during cutting so that the plasma torch circumferentially cuts the pipe while the pipe is being moved.
