SEALED UNION BETWEEN A TUBE PRESENTING A LEAK AND A SLEEVE AND PROCEDURE FOR ESTABLISHING SUCH UNION.

摘要

THE BUSHING IS ADDRESSED TOGETHER WITH THE RINGS FROM A FORMALLY HYDRAULIC HYDRAULIC NEMOTECHNICAL ALLOY OF THE TUBE. THE SPACE OF APPROXIMATELY 10 MICRONS THAT IS GENERATED AFTER FOCUSED FOR REASONS OF RECOVERY ELASTICITY IS CLOSED THROUGH A RING WARM UP. TO AVOID UNWANTED DAMAGE TO THE RING FLUSH, OR TUBE, A SEAL MUST BE PROVIDED WITHOUT PREVIOUS FLUSHING AND HOWEVER, GETTING A RELIABLE SEALING EFFECT. FOR THIS HAS BEEN ARRANGED IN THE SPACE (4) CANCEL BETWEEN THE BUSHING (3) AND THE TUBE (1) A PAIR OF SUPPORTING ELEMENTS (5), WHICH RECEIVE BETWEEN THEM THE PLACE OF WATER PATH (2) OF THE TUBE ( 1). EACH FIXING ELEMENT SHOWS IN A RESPECTIVE SCREW A RING (7,7A) BASED ON A NEMOTECHNICAL ALLOY OF FORM. THE TWO RINGS (7,7A) ARRANGED IN A SUPPORT ELEMENT ARE EQUIPPED WITH A DILATION CONTENT SUCH AS IN WARMING OVER A TEMPERATURE PREVIOUSLY GIVEN IN A COUNTER-DIRECTION DIRECTION A RADIAL FORCE IS EXERCISED ON THE FIXING ELEMENT. A PARTIAL ZONE OF THE FIXING ELEMENT IS PRESSED ON THE TUBE AND IN A PARTIAL ZONE ON THE BUSHING. THE SEAL IS PREFERABLY USED FOR THE REPAIR OF HEAT EXCHANGER TUBES.
