The present technology is generally directed to assembling and testing ampoules, and associated systems, devices, and methods. Each ampoule can include a body portion configured to carry a marking material within an interior of the body portion, and a base portion configured to couple to the body portion to seal the interior of the body portion. The ampoules can be assembled and/or tested in an inverted orientation. In the inverted orientation, the ampoule can include a gap between the marking material and the base portion. For example, the ampoule can be positioned within a leak detection system and the ampoule's gap can be aligned with one or more leak detection components configured to analyze the gap for leak-related indicia.

The invention concerns the field of container closure integrity (CCI) and the testing of CCI and relates to a device and a method for providing a displacement of a rubber stopper for leakage testing of a connection between the rubber stopper and a corresponding drug container which can be used for storing drugs under sterile conditions and which is closed by said rubber stopper.

A watertightness testing method for testing watertightness of a joined section (4) where one end section of a second pipe (3) is joined to a first pipe (2), the watertightness testing method including: inserting a testing device body (21) into the first pipe (2); attaching an assembling device (80) to another end section of the second pipe (3); attaching a pulling device (82a) to the assembling device (80) and connecting the pulling device (82a) to a strap-shaped member (112a) having been wound in advance around an outer circumference of the first pipe (2); operating the pulling device (82a) and pulling the strap-shaped member (112a) in a separating direction of the second pipe (3) to have a reaction force generated in the second pipe (3) cause the second pipe (3) to be pulled in a joining direction (G), the one end section of the second pipe (3) to be inserted into the first pipe (2), and the second pipe (3) to be joined to the first pipe (2); and operating a moving operation rod (22) provided in the testing device body (21) from outside of the other end section of the second pipe (3) in a state where the second pipe (3) is being pulled in the joining direction (G) to move the testing device body (21) to the joined section (4).

A fire sprinkler system according to one aspect of the present disclosure includes a pipe having a first pipe portion and a second pipe portion. The first pipe portion includes a wall having a first wall thickness, and the second pipe portion includes a wall having a second wall thickness that is greater than the first wall thickness. The fire sprinkler system further includes structure coupled to the pipe and defining a sealed chamber between the structure and at least the first pipe portion, and a sensor for sensing a pressure in the sealed chamber. Example corrosion monitoring devices and methods for monitoring corrosion in pipe systems, including fire sprinkler systems, are also disclosed.

A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.

A sealing device for a drive shaft is disclosed and described. The sealing device for a drive shaft comprises a housing disposed to surround the drive shaft between the inner space and the outer space, a plurality of sealing members axially separated from each other between the housing and the drive shaft to seal between the housing and the drive shaft, fixing ring members interposed between the plurality of sealing members to maintain the separation distance between the sealing members, and a fixing member secured to the housing to apply an axial pressure to the plurality of sealing members and fixing ring members, wherein a concave-convex section is formed on at least one of the close surfaces of the fixing ring member and the sealing member, which face each other.

The invention concerns the field of container closure integrity (CCI) and the testing of CCI and relates to a device and a method for providing a displacement of a rubber stopper for leakage testing of a connection between the rubber stopper and a corresponding drug container which can be used for storing drugs under sterile conditions and which is closed by said rubber stopper.

The present invention relates to a device for detecting leaks of liquids or gases caused by temperature variations, pressure variations, wear on the clamping and coupling devices, wear on sealing devices, by corrosive action, among others, in joints between pipes made by flanges (F) and together and basically comprises a strip (1) to be applied to the region of the “gap” (G) between flanges (F) with a pressure sensor (2) and protective caps (3) adapted to a screw head casing (PE) and nuts (P) employed for mounting between flanges (F).

The present invention relates to a system for detecting the watertightness or flooding of the annulus of flexible lines from a connector, comprising: an assembly of plunger (3) and cylinder (4) that are connected by a rod to a chamber (19) that acts as a pilot valve, connected directly to the outlet of a safety valve of a connector of the flexible line, in which same are fitted using a sealing system (6). The system is operated by commands sent to the ROV (2) that has an arm (21) and that controls the system using a handle (9). The present invention also describes the operating method of the device and how the obtained results lead to a preprogrammed conclusion regarding the watertightness (or otherwise) of the annulus. Other methods are provided to obtain fluid samples in the annulus for subsequent analysis and enable the safety valve to be removed from the connectors.

A gasket is for an annular compact flange. The compact flange includes two joinable flange halves which are formed with contact surfaces facing each other, and at least one of the flange halves having an axial, centric bore. An annular gasket groove is arranged in each of the flange halves, which is arranged to sealingly receive a common gasket. The gasket groove has a proximal side and a distal side relative to the bore, the distal side, which is conical, forming a groove sealing surface against the gasket. The gasket, which seals at the groove sealing surface, is formed with a plate portion positioned between the contact surfaces.
