ABSTRACT:
A fluid conduit composed of: two pipe sections each having a longitudinal axis and a connecting end, each pipe section including a cylindrical main portion, an annular flange located at the connecting end and extending radially outwardly from the main portion, and a thin annular disk located at the connecting end, extending radially outwardly from the flange and having an outer periphery, the pipe sections being assembled together at the connecting ends with the disks in contact with one another; and a mass of welding metal sealing the outer peripheries of the disks together.
Such a connection can be broken by cutting off outer peripheral regions of the disks along a circular cutting line.
