摘要： The invention relates to a device (1) for sealing ducts, comprising a store (3) containing pressurized air, a button (2) attached to the store (3), and a bag (4). The button (2) is used to release the pressurized air of the store (3), said button (2) comprising two horizontal parallel walls, each one of the parallel walls having a perforation at one end and an appendage (11) at the other end, that joins the parallel walls to each other and extends perpendicularly to the walls, and an L-shaped trigger (12) with one limb of the "L" located between the parallel walls and the other limb located parallel to the appendage (11). The limb of the trigger (12) parallel to the appendage is pressed by rotating the trigger (12) around the perforation and pressing a valve (19) contained in the store (3), releasing the pressurized air from inside the store (3) by means of said rotation.

摘要： The invention relates to a system for sealing a pipeline system, comprising a fluid-tight hose (1) for inserting into the area of the gap (2) between two pipes (3a, 3b) of a pipeline system to be sealed. The hose (1) is provided with a supply element (4) containing a valve (4a) for introducing the fluid into the hose (2), and the system is provided with a pump for conveying the fluid, wherein said pump can be connected to the supply element (4). In particular, the hose (2) contains material that can be vulcanized or welded, and the hose can be connected to a ring by vulcanization or welding. A very safe and easy-to-handle system for sealing a pipeline system is thereby created.

摘要： The invention relates to a device for sealing the end face of a tube from which fluid flows, wherein the device comprises an inner tube (1) which has a smaller diameter than the tube to be sealed and is introduced at the end face into the tube to be sealed, and a sealing body (6) which is provided to seal the ring gap between the inner tube (1) and the tube to be sealed. A turbine (3) is arranged in the area of the end face of the inner tube (1), which can be driven by the flowing fluid, wherein the rotational movement of said turbine is translated into a movement of the sealing body (6), thus bringing said sealing body from a position having reduced sealing capacity into a position having higher sealing capacity.

摘要： The invention relates to an assembly (1) comprising an elongate pipe (5) which extends along a central axis (7) and a plug (6a,6b) which is arranged in or on the pipe and which exerts a sealing force on the pipe in order to seal an open pipe end in a fluid-tight manner. The invention relates in particular to elongate pipes in offshore-structures in which the pipes are used as foundation piles. These foundation pipes can, in practice, be over 80 metres long and weigh 400-600 tons. As the transportation of these elongate and heavy pipes is laborious, there is a need for an alternative.

摘要： An inflatable bladder for blocking pipes, ducts, shafts, drains and the like. The bladder is connected to a pressurised fluid supply by a fluid communication means which is extendable, preferably telescopically extendable. The bladder is of variable thickness or specially reinforced at the ends or enclosed in a reinforced wire mesh bag or the like, to prevent uncontrolled axial extension under pressure.

摘要： A linestopping system for pipes includes first and second linestopping means (10a, 10b), each linestopping means including an inflatable plug (50), an inflation means (90) and an insertion means (34) and first and second branch pipe supports (20) each having an apertured flange (22) with a pipe section (24) mounted thereon at an acute angle, each pipe section containing a valve (28). In use, the pipe supports are disposed on a pipe in spaced apart locations with the pipe sections facing in opposite directions such that upon apertures being cut in the pipe at the pipe supports the inflatable plugs of respective linestopping means are inserted by the insertion means through the apertures in the pipe and subsequently inflated by the inflation means so as to seal off a section of the pipe. Each insertion means includes a plurality of sets of hydraulic clamps, a first set of clamps being fixed relative to the insertion means and a second sets of clamps being movable relative to the insertion means, such that the first and second sets are relatively moveable so as to cause insertion of the respective inflatable plug into the pipe. A bypass pipe (102) extends between the first and second linestopping means to allow fluid flow to be maintained when the section of the pipe is sealed off.
