ABSTRACT:
A pipe coupling for coupling pipe ends to each other, one pipe end having at its end an annular shoulder limiting the sliding of a first sleeve member over the pipe end. The second sleeve member is so dimensioned that it fits over a piping end and is welded to same. The two sleeve members are insertable into each other such that a clamping shell comprised of two half-shells hinged to each other engages exterior shoulders of the sleeve members at a location wherein the two sleeve members are overlapped one by the other. Preferably, the second sleeve member is integral with a flange for connecting the member to an existing sleeve on the respective piping end. The invention results in a short overall structure facilitating the use of the coupling with flanged pipe connections of a piping system.
