ABSTRACT:
A pipeline wherein one end portion of a first metallic pipe fits with annular clearance into the adjacent end portion of a second metallic pipe and the adjacent end portion has an internal groove for a radially and axially deformable ring which is biased radially inwardly and axially by a supply of gaseous, liquid or paste-like medium in the radially outermost part of the groove so that the free end of the adjacent end portion can be welded to the one end portion while the pipes convey a compressed gaseous fluid.
