Abstract
Abstract A new and improved pin-type vessel connector wherein a first vessel section includes double connector rings separated by an annular recess which receives a single connector ring of a second vessel section, the connector rings being releasably joined by a plurality of pin-type connectors which include radially aligned openings in each of the rings for receiving a tapered pin, one portion of the opening in the single ring connector being partially tapered to provide a full bearing engagement against the tapered pin under load conditions. Positioning elements are mounted with the single connector ring for positioning the single connector ring uniformly within the annular recess between the double rings in spite of changes in the circumference or roundness of the single ring.
