<p>Sleeve part of a pipe joint (1), which sleeve part comprises a chamber space, into which the opposing butt ends (5, 6) of the pipe parts (2, 3) to be connected together are placed such that the sleeve part (4) extends a distance from the point of connection of the pipe parts (2, 3) to be connected together on top of both pipe parts (2, 3), which sleeve part (4) comprises heating means (7), such as resistance wires, as a consequence of the heating of which resistance wires a joint forms between the sleeve part (4) and the pipe parts (2, 3). An inspection aperture (8) is formed in the sleeve part (4) through the wall of the sleeve part from the exterior to the interior to a point where the positioning of the opposing butt end surfaces (5, 6) of the pipe parts (2, 3) to be connected together can be verified. The invention also relates to a pipe joint.</p> |
