<p>The invention relates to equipotential equipment to be connected to networks, to be tightly fitted to pipeline systems and/or their fittings, made of electrically conductive material, which is constructed in a way that it makes the electric potential of the medium inside the pipeline system appear on the external touchable surface of the equipment, and ensures a lasting and reliable electrical connection for the pipe joint piece or electric cable in metallic contact with it. The characteristic feature of the invention is that the hollow pipe fitting part (2) is made of a conductive material, and the pipe joint unit (1) made of conductive material is in metallic contact with the external surface of the hollow pipe fitting part (2), and the pipe fitting piece entering (3) the pipe fitting part (2) and the pipe fitting piece leaving (4) the pipe fitting part (2) are joined tightly.</p> |
