A leak detection system configured to be attached on an exterior of a conduit to detect a leak in a non-pressurized conduit. The leak detection system includes a first fluid section and a second fluid section that each includes the same or similar fluid volumes. The first fluid section includes a testing chamber configured be attached to the conduit. With the testing chamber positioned on the conduit, a pressure sensor connected to each of the first and second fluid sections senses a difference in the fluid pressure between the first and second fluid sections to detect a leak.

A method for testing a device under test includes the steps of applying a vacuum to an interior of the device under test. Pressurizing a predetermined portion on an exterior of the device under test with Helium to detect a potential pressure leak. Utilizing a large pressure differential during the exterior testing of the device under test as compared to the vacuum applied during to the interior of the device under test. Detecting a potential leak in the device under test while leaving no residual Helium in a wetted area of the device under test.

A system for detecting leaks comprises at least one pipeline element, a leak detection device, and a pre-formed, heat-shrinkable sleeve comprising at least one inlet aperture. A method of manufacturing the sleeve comprises the steps of applying a cross-linkable material around a standard-sized sleeve mold, cross-linking the material, removing the cross-linked material from the mold, heating and stretching the cross-linked material around a stretching sleeve mold, allowing the material to cool, and removing the cooled sleeve from the mold. A method of monitoring a leak comprises the steps of receiving the pipeline element in the sleeve and applying heat to the sleeve, whereby the sleeve shrinks and conforms substantially around the profile of the pipeline element and at least a portion of the leak detection device.

The present disclosure provides a sealing apparatus for use in a hypertube, which includes a first tube, a second tube having one end connected to an end of the first tube, and a gasket including a seal made of a fiber structure formed with a space that is filled with a sealing fluid, wherein the gasket is configured to seal a space between the first tube and the second tube.

A work machine that can detect abnormality such as a malfunction and wear and tear of each of hydraulic pumps including control equipment with high precision and that can reduce equipment cost is provided. A controller 9 according to the present invention includes a volumetric-transfer-efficiency-calculating section 94 that calculates a volumetric transfer efficiency .sub.C representing a transfer efficiency of hydraulic oil between a hydraulic cylinder 11 and hydraulic pumps 21 to 23 on the basis of a target discharge flow rate calculated by a target-discharge-flow-rate-calculating section 932 and the speed of the hydraulic cylinder 11 that is detected by a speed sensor 28, and an abnormality decision section 95 that decides whether any one of the hydraulic pumps 21 to 23 is abnormal on the basis of the volumetric transfer efficiency .sub.C calculated by the volumetric-transfer-efficiency-calculating section 94.

A containment sump has a primary container and a secondary container which extends only partway up the outer wall of the primary container. This low-rise secondary container, in certain embodiments, cooperates with the primary container to create a hermetically sealed interstitial space encompassing the bottom of the primary container, including the lower portion of the upright containment wall and the container bottom. In alternative embodiments, the secondary container is a subassembly forming an interstitial space and joined as a subassembly to the primary container. More particularly, the upper end of the interstitial space may be below pipe or other conduit penetrations through the sidewall of the primary container. At the same time, any leak which may develop over the service life of the containment sump would be contained and detected within the bottom of the primary and/or secondary containers. Therefore, the present system combines the low cost and high reliability associated with single-wall penetrations through containment sump walls, while also offering the high level of environmental protection associated with double-wall spill containment.

A connection comprising a first duct, a second duct, a flexible tube which comprises a first end configured to cover part of the first duct, and a second end configured to cover part of the second duct, a first clamping system configured to clamp the first end of the flexible tube around the first duct, and a second clamping system configured to clamp the second end of the flexible tube around the second duct.

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.
