Abstract
An insulating joint for pipelines comprises two metal tubular parts each having a dilated end portion, the dilated portion of one of the tubular parts being located within the dilated portion of the other tubular part and the dilated portions extending substantially parallel to each other so as to form a gap therebetween, two sleeves composed of an insulating material and forcefully introduced into the gap one after the other in a longitudinal direction so as to form a space therebetween, and a gasket located in the space and forcefully compressed between the two sleeves.

An insulating joint for pipelines, comprising two metal tubular parts having similarly dilated end portions, the dilated end portion of one of the two metal tubular parts being located within the dilated end portion of the other of the two metal tubular parts and extending substantially parallel to the dilated end portion of the other of the two metal tubular parts in a radially spaced relationship relative thereto to form a gap therebetween;
- two sleeves composed of an insulating material, having a cross-section substantially similar to a cross-section of said dilated end portions and located in said gap one after the other in a longitudinal direction with each sleeve engaging said dilated end portions of said two metal tubular parts, said two sleeves having longitudinally spaced facing end surfaces, respectively, forming a longitudinal gap therebetween;
- and a gasket located in said longitudinal gap and compressed between said two facing end surfaces of said two sleeves.
