摘要： Leak detection device having a dome with a main body and a seal configured to define a detection chamber between the main body and the test zone, the seal including a peripheral sealing lip configured to come into contact with the sealing membrane and having a closed contour encircling the detection chamber, an analysis tool connected to the detection chamber to analyze a gas present in the detection chamber in which the sealing lip is configured to have at least in a service state in which a reduced pressure is applied in the detection chamber, a pinch portion that is pinched between the main body and the sealing membrane.

摘要： The invention relates to a tracing method (2000) for constructing a liquefied gas storage facility (1). The facility (1) comprises a sealed and thermally-insulating tank (20). A bottom wall (21) of the tank (20) includes a plurality of angular sectors (25) which are images of each other through rotation by a predetermined angle about a vertical axis, the predetermined angle being equal to k.360°/N, where k is a positive integer. A vertical wall (22) of the tank (20) comprises a vertical row (120) of planar insulating wall modules (131, 131A) disposed on each vertical load-bearing section (14) of a load-bearing structure of the tank. The tracing method ensures that an azimuthal angular deviation with respect to said vertical axis between two rows (120) of planar insulating wall modules (131, 131A, 171) disposed on two adjacent vertical load-bearing sections (14) is equal to 360°/N, preferably with an accuracy better than 5 mm.

摘要： The invention relates to a leak detection device comprising: a portable leak detection bell-like member comprising a sealing joint and configured to define a detection chamber between the main body and the test zone, the detection bell-like member further comprising a carrying handle which is provided with a control member which can be manually activated to produce a control signal, a gas suction circuit which is intended to connect the detection chamber to a vacuum pump, the gas suction circuit being provided with a controlled valve which can be switched into an open state to connect the detection chamber to the vacuum pump and a closed state to isolate the detection chamber from the vacuum pump, and a control unit which is configured to switch the controlled valve in response to the control signal.
