ABSTRACT:
A bellows-type pipe junction for mechanically joining the spaced-apart ends of two pipes in a liquid-tight manner includes two sleeve sections fitted onto the two pipe ends and a flexible offset section joined at its two ends to the two sleeve sections by respective flexible bellows-type joints. The flexible offset section and the flexible bellows-type joints provide a fluid-tight junction while accommodating axial and radial offsets between the two pipe ends. The pipe junction is especially suitable for joining the pipes of an aircraft drain mast.
