Insulation piece for a pipeline

An insulation piece for a pipeline conveying an electrically conductive liquid from a point which is at a ground potential to a point connected to a high voltage, the liquid being conveyed discontinuously by portion-by-portion transport due to a flow of the liquid being interrupted at times, so that the insulation piece is one of periodically free and substantially free, of the liquid, corresponding to interruptions in the flow, the insulation piece comprising:

• a hollow body having end faces and an unobstructed width equal to or greater than a width of the pipeline to be connected to;
• terminating elements disposed in said hollow body in a region of said end faces of said hollow body and said terminating elements closing off at least in places, parts of said end faces;
• and
• connecting pieces for connecting to the pipeline, said connecting pieces each having a diameter equivalent to a diameter of the pipeline, said connecting pieces each having an external end prepared for connection to the pipeline, an internal end disposed in said hollow body, and a toroidal-shaped attachment formed on an outside area of said internal end, each of said connecting pieces passing through an associated one of said terminating elements and resting against said associated one of said terminating elements to form a seal.
