Arrangement for Separating a Connection Between Two Pressurized Flanged Tube Sections
First Claim
1. An arrangement for separating a connection between two pressurized flanged tube sections, the arrangement comprising:
- a first type element comprising a first body adapted to be arranged around a flange of a first tube section of said connection, and which first body comprising a first sealing arrangement,a second type element comprising a second body adapted to be arranged around a flange of a second tube section of said connection, and which second body comprising a second sealing arrangement, and wherein the second type element further comprises a displaceable obstruction,wherein the first type element and the second type element are adapted to form a sealed compartment between the flange of the first tube section and the flange of the second tube section, and the first sealing arrangement and the second sealing arrangement are adapted to maintain the sealing of the sealed compartment while allowing the flange of the first tube section and the flange of the second tube section to be displaced away from each other so that a gap is formed, which allows the obstruction to enter and isolate the second tube section.

Abstract
An arrangement is for separating a connection between two pressurized flanged tube sections. The arrangement comprises a first type element having a first body adapted to be arranged around a flange of a first tube section, and which first body comprising a first sealing arrangement, and a second type element comprising a second body adapted to be arranged around a flange of a second tube section, and which second body comprising a second sealing arrangement. The second type element further comprises a displaceable obstruction. The first and the second type elements are adapted to form a sealed compartment that allows the flanges of the tube sections to be displaced away from each other so that a gap is formed, which allows the obstruction to enter and isolate the second tube section.

19. A method for separating a connection between two pressurized flanged tube sections by means of an arrangement comprising a first type element comprising a first body comprising a first sealing arrangement, and a second type element comprising a second body comprising a second sealing arrangement, and wherein the second type element further comprises a displaceable obstruction, wherein the method comprises:
-
arranging the arrangement on the connection so that the first type element is positioned around a flange of a first tube section and the second type element is positioned around a flange of a second tube section, and so that the first type element and the second type element form a sealed compartment between the flange of the first tube section and the flange of the second tube section, arranging a connection assembly so that the first type element and second type element exert a force on the flanges of the first tube section and the second tube section, removing one or more bolts of a bolt assembly between the flange of the first tube section and the flange of the second tube section, displacing the flange of the first tube section and the flange of the second tube section away from each other so that a gap is formed within the sealed compartment between the flange of the first tube section and the flange of the second tube section, and displacing the obstruction into the gap between the flange of the first tube section and the flange of the second tube section . - View Dependent Claims (20, 21, 22)

23. A method for re-establishing a connection of a first tube section to a pressurized isolated second tube section by means of an arrangement comprising a first type element comprising a first body with a first sealing arrangement, and a second type element comprising a second body with a second sealing arrangement, and wherein the second type element further comprises a displaceable obstruction, where the second type element is arranged around a flange of the second tube section, wherein the method comprises:
-
positioning the first tube section next to the second tube section, arranging the first type element around a flange of the first tube section of said connection to be formed so that the first type element and the second type element forms a sealed compartment between the flange of the first tube section and the flange of the second tube section, arranging a connection assembly for connecting the first type element and second type element together, connecting one or more bolts to form a bolt assembly between the flange of the first tube section and the flange of the second tube section, displacing the obstruction out of a gap between the flanges of the two tube sections), and displacing the flange of the first tube section and the flange of the second tube section towards each other so that said gap formed between the flanges of the two tube sections is closed. - View Dependent Claims (24, 25)

26. A method for re-establishing a connection of a first tube section to a pressurized isolated second tube section by means of an arrangement comprising a first type element comprising a first body with a first sealing arrangement, and a second type element comprising a second body with a second sealing arrangement, and wherein the second type element further comprises a displaceable obstruction, where the first type element is positioned around a flange of a first tube section and the second type element is positioned around a flange of a second tube section so that the first type element and the second type element form a sealed compartment between the flange of the first tube section and the flange of the second tube section, wherein the method comprises the steps of:
-
connecting one or more bolts to form a bolt assembly between the flange of the first tube section and the flange of the second tube section, displacing the obstruction out of a gap between the flanges of the two tube sections, and displacing the flange of the first tube section and the flange of the second tube section towards each other so that said gap formed between the flanges of the two tube sections is closed. - View Dependent Claims (27, 28)
