Pipeline for gaseous fluids and method of assembling its components

Patent ·
OSTI ID:6009657
In a pipeline, particularly for compressed gaseous fluids, the combination of a first tubular member is described which includes a first end portion having an external surface. A second tubular member includes a second end portion having an internal surface surrounding the external surface, a free end, and a ring-shaped groove extending radially outwardly from the internal surface. The groove has axially spaced apart side walls; means for bonding the free end to the first end portion; a deformable ring between the side walls of the groove; and means for deforming the ring radially inwardly into sealing engagement with the external surface of the first end portion and axially into sealing engagement with the side walls independently of the fluid in the pipeline. This allows for the application of the bonding means, particularly an annular weld, while the pressure in the tubular members deviates from the pressure of the surrounding atmosphere.
