Title: AN ARRANGEMENT FOR SEPARATING A CONNECTION BETWEEN TWO PRESSURIZED FLANGED TUBE SECTIONS
Abstract:
An arrangement (1) for separating a connection (3) between two pressurized flanged tube sections. The arrangement comprises a first type element (10) comprising a first body (20) adapted to be arranged around a flange (22) of a first tube section (5), and which first body comprising a first sealing arrangement (24), and a second type element (12) comprising a second body (30) adapted to be arranged around a flange (32) of a second tube section (7), and which second body comprising a second sealing arrangement (34). The second type element further comprises a displaceable obstruction (50). The first and the second type elements are adapted to form a sealed compartment (52) that allows the flanges of the tube sections to be displaced away from each other so that a gap (54) is formed, which allows the obstruction to enter and isolate the second tube section.
