A test tool and related method for testing a blowout preventer (BOP). The test tool includes a first sub, a first pipe adapted to be connected to, and disconnected from, the first sub, the first pipe including an external spline, a second sub adapted to be connected to, and disconnected from, the first sub, the second sub including an internal spline adapted to engage the external spline of the first pipe, and a second pipe adapted to be connected to the second sub. The test tool includes an operational configuration in which the internal spline of the second sub engages the external spline of the first pipe so that a torque is transferable from the second sub to the first pipe via at least the engagement between the internal spline and the external spline. One or more high pressure low torque (HPLT) connections are incorporated into the test tool.

Methods and systems are provided for conducting a diagnostic routine of the fuel vapor system using pressure generated by raising or lowering a vehicle body element such as a hood or a trunk. In one example, by utilizing lift gate cylinders coupled to the hood or trunk, during raising a hood or trunk, the fuel vapor system may be evacuated and during lowering the hood or trunk, the fuel vapor system may be pressurized. A change in vacuum or higher pressure in the fuel vapor system may be monitored over a time period to detect any undesirable evaporative emissions from the fuel vapor system.

A system and method for cleaning and inspecting ring frames is disclosed here. In one embodiment, a vacuum valve comprising at least one sealing O-ring; and a pressure monitoring tape on a mating surface on a vacuum processing chamber, wherein the pressure monitoring tape is configured to perform a pressure profile mapping between the mating surface on the vacuum processing chamber and a surface of the at least one sealing O-ring on the vacuum valve to determine a closing condition of the vacuum valve.

A turbine inspection stopper is provided, including a main body and a pressure gauge. The main body has a base portion, an annular flange which is laterally disposed around the base portion and an air passage, the annular flange is for being connected to one of two ends of a turbine, the base portion and the annular flange define an interior space, the interior space is for communicating with an interior of the turbine, and the air passage is for communicating with outside and the interior of the turbine; and at least one part of the pressure gauge is buried in the main body and communicates with the interior space.

A ventilation and leak detection system for use in an enclosure includes a ventilation duct extending at least partially through an interior chamber defined in the enclosure. The ventilation duct includes at least one inlet end positioned within a lower portion of the interior chamber and an outlet end. The at least one inlet end includes at least one opening defined therein and sized to enable air and fuel within the enclosure to be drawn into the ventilation duct to ventilate the enclosure. The system further includes a detection unit coupled in flow communication with the ventilation duct proximate to the outlet end for detecting fuel entrained within flow drawn into the ventilation duct.

A plug for isolating and pressure testing a hollow piece of equipment (e.g., a container or tubular) comprises a compression nut, a semi-conical mandrel shaft (which may be one or two pieces), and a compression member. The compression nut and the semi-conical mandrel shaft are threaded together, directly or indirectly via a spacer and plug body, such that the rotation of the compression nut forces the mandrel shaft through the compression member, and the semi-conical surface expands the compression member against an interior surface of the hollow piece of equipment to anchor in place and seal off a testing space. Internal channels running through the compression nut (and if present, the plug body) permit externally pressurized fluid and sensors to communicate with the testing space. The compression member can be configured to test either one end of the piece of hollow equipment or a particular region between the two seals.

A method for inspecting a seal of a flexible container for a fluid, particularly a fluid medication, includes covering the container at least in part—preferably completely—by a gas-permeable layer. The container, together with the gas-permeable layer, is arranged in a flexible, substantially gas-tight bag, and the substantially gas-tight bag is evacuated by pumping out via a bag opening. The container is filled with a noble gas, and the presence of noble gas, which escapes out of the bag opening from the container via a leak through the gas-permeable layer, is detected.
