Look identical in size and detail.
  • When installed horizontally the ribs, fibrecomposite occurs due to the bending, not compression and extension. Detail is usually installed in the first pipe elbow, if counting from the engine. With the same range of diameters (up to 65 mm) corrugations of this type can reach 400 mm in length. But the choice of the replacement exercise, starting from two parameters. First – the possibility of welding: if we can cut current seam so that the pipe sections included in the pipes remained intact? If Yes, then take the previous corrugation length.
