ABSTRACT:
A seal assembly for an articulated coupling of two pipes has a first flange adapted for affixation to the end of a first pipe, a first slide face on the first flange, and a second flange adapted for affixation to the end of a second pipe. The second flange has an annular part including an engagement face oriented towards the first flange and a tubular nipple projecting towards the first flange. The seal assembly further has a sheet metal ring surrounding the tubular nipple and having a generally U-shaped cross section for defining a ring cavity open towards the engagement face. A second slide face, provided on the outer surface of an outer wall portion of the sheet metal ring, is surrounded by, and is in a sliding contact with, the first slide face. An annular filler mass of a sealing material is received in the cavity. The filler mass extends axially beyond the sheet metal ring and is in contact with the engagement face of the annular part of the second flange. A force exerting arrangement presses the first and second slide faces axially to one another.
