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.
An arrangement for separating a connection between two pressurized flanged tube sections, the arrangement comprising:
The arrangement according to claim 8, wherein the lock device comprises a further obstruction controllably displaceable into and out of the entrance to the channel for opening and closing the entrance to the channel.
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:
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:
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:
