device for rapid junction of steel pipelines of large diameter pipelines, particularly submarines.

摘要

the device includes a pair of sealing bodies and restraint to external profile troncoconico compressible radially and calzabili on the end of one (t1) of the tubes of giuntare.the one giustapposto in the correspondence of the respective sections more (ms - ms); a pair of collars cuneiform (15 - 15).calzabili on their bodies of resilience and restraint (11 and 11), and a conical internal surface events each (hoity toity) designed to cooperate in efforts to contact with the conical surface forced esterna (see eea) of the corresponding body sealing and restraint and a conical outer surface (sce (sce) act to bind the corresponding internal conical surface (you know - you know ') of a ring (16) of kingaction; a pair of rings torici deformable and cables (19, 19 '), the cuneiform collars axially agents (15, 15') and reagents on corresponding lines (17, 17 ') of the reaction ring (16), whichthe effect of the pressure of a hydraulic fluid fed in their cavity.force axially between the respective collars cuneiform body sealing and restraint (11, 11 ') and the ring (16) until the reaction irreversible block of time (fig. 1).
