A system for detecting the watertightness or flooding of an annulus of flexible lines from a connector. The system includes: an assembly of plunger and cylinder that are connected by a rod to a chamber that acts as a pilot valve. The assembly is 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. The system is operated by commands sent to a ROV that has an arm and that controls the system using a handle.

The present disclosure relates to a sensor system for monitoring the sealing of the connection between a sensor holder and a sensor that is mounted on the sensor holder. The sensor system includes a sensor holder, a sensor that is mounted on the sensor holder, and a leakage detector with a channel, which is arranged in the sensor holder and consists of one or more straight sections that are mounted perpendicular or parallel to the longitudinal axis of the sensor.

A portable appliance testing apparatus includes a water tank and a pump configured to draw water from the water tank and pressurize the water within a piping assembly. The apparatus further includes a pressure regulator switch coupled to the piping assembly to enable control of the pump based on a pressure within the piping assembly. The apparatus also includes at least one appliance connector coupled to the piping assembly to enable attachment of an appliance thereto.

A system (100) for testing is disclosed. The system (100) comprises a pipe joint having a male pipe section (102) and a female pipe section (104), a test port (106) disposed in a test space provided on the male pipe section (102) and a testing apparatus. The testing apparatus comprises a needle (112), a tubing (114) attached to the needle (112), a pressure supply assembly (116) attached to the tubing (114) in order to provide a predetermined air pressure while testing of the pipe joint and a ballast (118) adapted to support and hold the tubing (114) in order to provide necessary length of the tubing (114) to insert the needle (112) inside the test port (106). Further, the test port (106) is fixed into the interior diameter of the male pipe section (102) and is secured into the test space of the male pipe section (102) using a fastening means.

The invention discloses an on-line sealing detecting device, which is set on a butting surface of two parts, and includes: a seal ring, which is installed in the butting surface of two parts, and a circumferential chamber, which is set in this seal ring at least; an inlet and outlet unit, which is connected with the inner of the chamber, and one detection unit is set on this inlet and outlet unit at least. This detection unit is connected with a processor through electric connection and is used for detecting the gas pressure value and/or gas concentration value in the inlet and outlet unit, an for sending then the gas pressure value and/or gas concentration value to the processor. At the same time, this invention discloses a multi-section-type seal chamber processing equipment and an on-line sealing detecting method. Compared with the existing technology, this invention can realize an on-line detection of part sealing, and detect each operation position of multi-section-type seal chamber processing equipment at the same time, which can effectively improve the sealing detection efficiency of multi-section-type seal chamber processing equipment.

The present invention discloses a system comprising a hydraulic plate assembly, a hydraulic grapple pipe connection assembly, hydraulic circuit assembly, or a combination thereof to set and attach pipe connections to equipment, such as oilfield equipment and method(s) of using the system. The use of this system makes the process of attaching the connections to the pipe safe, quick and easy.

A system (100) for testing a pipe joint comprises a pipe joint having a male pipe section (102) and a female pipe section (104), a test port (106) disposed in a test space provided on the male pipe section (102) and a testing apparatus comprising a needle (112), a tubing (114) and a pressure supply assembly (116). Further, the test space is a cavity provided in the male pipe section (102). Further, test port (106) connects an annular space (110) created at a junction of the male pipe section (102) and female pipe section (104) by providing gaskets (108). Further, the tubing (114) comprises a puck (805) adapted to extract the needle (112) from the test port (106).

Disclosed is a system for testing the tightness of a cable gland feed-through of a partition, in particular of an immersible electrical connector, of the type including a cable gland body in which a seal and a cable gland rammer for compressing the seal are placed, characterized in that it includes a tightness testing ring inserted in the seal and provided with a bore opposite a hole of the cable gland body opening on same, and provided with a connection to a pressure/vacuum source for testing the tightness of the cable gland.

Hydrostatic test tool 100 comprises frame 161; pressurizer 120; connection system 110; control system 130; data communicator 140; power supply 150; device handler 162; and buoyancy unit 163. Hydrostatic test tool 100 can be used to perform an in situ seal test of subsea equipment connectors with limited support from external systems, allowing optimization of subsea operations by not requiring constant support from underwater vehicle 5, which could be used to perform other tasks while the test is being carried out, optimizing the total time of support vessel 6 and reducing operational cost. Hydrostatic test tool 100 typically requires interfacing with underwater vehicle 5, e.g., an ROV or AUV, only for deployment/installation and data communication, if at all.

An apparatus for hydrostatic testing of openings in items surrounded by a flange, such as flanged pipe sections, flanged pipelines, flanged hose assemblies, as well as other flanged equipment requiring initial and/or periodic pressure testing.
