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 present invention provides a method of manufacturing a pipe liner for lining the inside of a pipe, for example a water or sewerage pipe requiring repair. The pipe liner is mainly formed of a fabric sleeve, or a plurality of fabric sleeves, and comprises a fluid-proof barrier coating on the inside surface of the pipe liner. The method involves arranging a strip of carrier material comprising a liquid sealant inside the fabric sleeve of the pipe liner and in registration with two opposing side edges of the sheet of fabric, facing an inner barrier coating of the fabric sleeve. The method can advantageously provide such a pipe liner with an inner barrier coating without everting the pipe liner after manufacture. The present invention may also provide a way of avoiding internal cross-welding of said pipe liners and a method for testing the integrity of the barrier coating of said pipe liners. The present invention also provides an apparatus for carrying out these methods.

A device for monitoring the tightness of a sealing component wherein the monitoring device has a box with a peripheral partition and a cover made of a transparent material is disclosed. The cover is connected to the peripheral partition such that the cover and the peripheral partition are able to define, with a sealing component, an inner chamber, the peripheral partition with an inner peripheral wall having a lower end equipped with an inner peripheral seal intended to be positioned against the sealing component all around the inner chamber, and an outer peripheral wall arranged outside the inner peripheral wall so as to define, between the outer peripheral wall and the inner peripheral wall, an intermediate chamber extending exclusively in the peripheral partition all around the inner chamber.

An inspection system is configured to inspect the condition of a braze joint formed within a structure, wherein the braze joint is formed from a braze filler material having a tracer material disposed therein. The inspection system includes an energy source for directing energy towards the structure, an energy detector for detecting information regarding the structure following interaction with the energy directed from the energy source, and a data analysis system for analyzing the information detected by the energy detector. The data analysis system is configured to distinguish the tracer material from the remaining materials forming the structure in order to determine a suitability of the braze joint.

A lithium ion battery (11) that is a test object is housed in a vacuum chamber (14). An initial exhaust pipe (47) and an inspection exhaust pipe (51) are connected to the upper portion of the vacuum chamber (14). The inside of the vacuum chamber (14) is subjected to an initial exhaust through the initial exhaust pipe (47) to lower the pressure inside the vacuum chamber (14) to an inspection pressure (Pe). Thereafter, an inspection exhaust is performed through the inspection exhaust pipe (51). A sensor unit (16) is interposed in the inspection exhaust pipe (51). Exhaust gas passing through the inspection exhaust pipe (51) flows into the sensor unit (16) from an inlet port, and is caused to flow perpendicularly toward the sensor face of a gas sensor by a nozzle provided inside the sensor unit (16). The exhaust gas passes through the inside of the gas sensor, and is discharged to outside of the sensor unit (16) from an exhaust port.

A leakage detection system for spent fuel cooling pools is related to the field of testing and measurement instrumentation and is aimed at monitoring leakages in the storage facilities, mostly in spent fuel cooling pools at NPPs.

In the leakage detection system for spent fuel cooling pools the welded joints in the pool are additionally fenced with a metal guard which are connected via valve installed tubes to the pipeline, which, in turn, is connected on both of its sides to the leakage collector tank via a receiving valve and a return valve. The leakage collector tank is equipped with a level control sensor.

A leakage detection system for spent fuel cooling pools ensures control over airtightness of welded joins in the pool and allows for detection of leaking welded joints without preliminary emptying the pool which enhances the radiation safety of the pool and reduces the maintenance time.
