-11- "JUNCTION MEANS FOR CRYOGENIC PIPELINES FOR ALLEVIATING AXIAL STRESS" ABSTRACT OF THE DISCLOSURE One end of the pipe is flanged and a matching collar is engaged over the pipe either from the plain end prior to the end being flanged or flared. The pipe to be formed is also flared to a slightly larger extent to form a female flare and the flared end of the first pipe is engaged into the flared end of the further pipe whereupon the collar is engaged over the flared end of the first pipe to butt against the flared end of the further pipe and the junction between the collar and the flared end of the further pipe is welded. When the line is placed in service, with attendent shrinkage, a pressure is developed between the collar and the flared end of the first pipe sufficient to prevent leakage of the product. In addition, angular misalignment of the two pipes may be accommodated by making the flared ends partially spherical.
