Improvements in couplings for Flexible metal conduit Tube Union Submarines to grandesprofundidades perched

摘要

Coupling between flexible metal tubes subjected to high pressures. Includes two metal tubular sleeves (4 and 5) set at the respective ends of the tubes by Welding (1 and 2) and (6) that are linked by a Flexible metal structure (7).This structure is composed of a metal Bellows (8) that has its ends fixed to the estancamente sleeves (4 and 5) and that is reinforced by Steel externally closed Rings (11).Coaxial with the Bellows and inside there is a Ring structure (12) articulated thanks to its cross section or opens Alternately in each, outward and inward.
