The invention relates to a leak detection device comprising:

Leak detection device

The invention relates to a tank () for storing a liquefied gas, wherein the tank () includes peripheral walls (), the peripheral walls () including a sealing membrane and at least one thermal insulation barrier,

Sealed and thermally insulating tank comprising anti-convective filling elements

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.

The invention concerns a forming device intended to form a bend in a corrugation, the forming device comprising:

Forming a bend in a corrugation

The invention relates to a bending device for forming corrugations in a metal sheet including:

Folding device for simultaneous formation of a plurality of corrugations in a metal sheet and method for use of said device

A bending device for forming a corrugation in a metal sheet, the bending device having a frame, a die having two die elements, each having a concave half-impression, mounted able to slide on the frame; a punch having a head able to engage inside the impression of the die so as to press the metal sheet; and two side clamps mounted sliding and able to move vertically with respect to the lower frame so as to clamp the metal sheet against the bearing surfaces of the die elements. During the displacement of the punch into its bending position, the metal sheet transmits a traction force to the die elements and to the side clamps so as to displace them into their near position.
