<p>The tool forces the flanges of a pipe joint apart, having a set bolt movable axially in a hole through one of the flanges. A guide sleeve (8) is provided for the set bot (6) in the hole, being typically a cylindrical end portion of the set bolt, which is self-tapping, or alternatively such a portion of an auxiliary collar (7) which has a tapering self-tapping screw thread and in which a set bolt works. The latter can be arranged to act against a mating support component, fitted in the corresponding hole in the other pipe flange.</p> |
