<p>In the positioning of an additional tubular element, e.g. a pipe section, on a tubular structure, e.g. a pipe-line in the course of immersion, where the end surfaces to be brought into contact are not in radial planes, the additional element is brought in alignment with the structure and at a short distance from the latter. The end surfaces of the element and structure are then brought into contact, the contacting ends are centered, and a compressive force is applied to them in such a way that the element can pivot about the point of contact between the element and the structure until its end surface is brought into complete contact with the end surface of the structure.</p> |
