Pipeline compensator for axial, angular, and lateral motion - has third bellows inserted in intermediate pipe, supported against lateral and angular motion

摘要

The compensator absorbs lateral, angular, and axial movement between two pipeline ends (1, 2) and is tightly joined by tubular connecting ends. It has two annularly corrugated bellows (3, 4) between which is fitted an intermediate pipe (5, 6). A third bellows (7) is inserted into the intermediate pipe and is supported by an inner or outer pipe parallel to it, with an inner or outer slightly less or more than those of the third bellows. Arms (10-13) protrude from parts of the intermediate pipe and fromt he connecting ends. ADVANTAGE - Reduced risk of destruction for the first two bellows.
