Abstract

The subject of the invention is an insulating pipe joint designed for incorporation into a pipeline, said pipe joint having a spark gap. The insulating pipe joint according to this invention consists of two tubular steel components 1, 3 and of an insulating and sealing sleeve 2 positioned between the said steel components. Spark gap 4 is located beyond the outer edge of the first steel component 1 and has the form of a gap between the edge of the steel component 1 and disk 5 attached to the second steel component 3 facing the insulating and sealing sleeve 2. The height of notches in the steel component 3 and in the insulating and sealing sleeve 2 is set to satisfy the following relationship: one half of the difference between outer and inner diameter of these components is equal to the height of the notches.

Claims

AMENDED CLAIMS received by the International Bureau on 13 decembre 2007 (13.12.2007)
An insulating pipe joint for incorporation into a pipeline, the said joint comprising two mutually insulated steel components with a spark gap located between the outer edge of the first steel component and a disk attached to the second steel component facing an insulating separator, wherein the gap is enclosed in insulating material and the surface of the disk facing the insulating separator is irregular, preferably in the form of V-shaped hump or projections, characterized in that an insulating and sealing sleeve (2) is positioned between two tubular steel components (1_) and (3), wherein the entire inner surface of the sleeve (2) and the outer surface of the contracted end portion of one of the tubular components (3) is furnished with circumferential notches, wherein the height of the notches in the steel component (3) and the height of notches in the insulating and sealing sleeve (2) which is is set to satisfy the following relationship: one half of the difference between the diameter of the notch bottom and the inner diameter of this component constitutes the height of the notches.
