The invention relates to a hydraulic proof test assembly comprising at least a valve (1) with parallel seats (102). It comprises: a shut-off member (2) with parallel plates (20, 21), connected by connecting means for regulating their separation, to make them go from a first position in which this separation is sufficient to enable the shut-off member (2) to be introduced into said valve (1) to a second position where said separation is greater, this separation making it possible to apply them firmly against said parallel seats (102); a device (3) for inserting said shut-off member (2) into said valve (1) which comprises at least a “U” shaped tool, configured to be introduced into said valve (1), its parallel arms forming guides, while its base forms a support for retaining said shut-off member (2); a “dummy stem” (4).

A test apparatus and method for use, in situ, to identify leaks in individual tubes in an air-cooled heat exchanger includes a pressurizing component and a pressure retaining component that are secured in the opposite ends of an individual tube by engagement of a lock member in the threaded opening in the respective adjacent headers from which the access port covers have been removed. A pressurized test liquid, e.g., water, is admitted via the test apparatus pressurizing component to fill the tube by initially venting and then closing a drain valve on the pressure retaining component and controllably increasing the hydrostatic pressure on the tube to a predetermined value and monitoring a gauge in the pressurizing component for any loss of the final test pressure, thereby confirming a leak, after which the tube is drained and sealed to remove it from service.

Disclosed are systems and methods for pressure testing coiled tubing (CT) in a well. A CT pressure testing device may include a CT connector for attaching to a CT segment and a pressure test housing defining a pressure chamber. A rod may extend through a top opening of the pressure test housing and through the CT connector to the severed end of the CT segment. A sealing plug coupled to a bottom end of the rod may create an interface between the CT connector and the CT segment. A force activator may apply a force to a top end of the rod, causing the rod to push the sealing plug into the CT segment and tighten the interface. A pump may pressurize the pressure chamber to perform a pressure test on the sealing plug. Accordingly, the CT pressure testing device may establish a well control barrier for the well.

Techniques implementing and/or operating a system includes a pipe segment and a test head assembly secured to the pipe segment. The pipe segment includes tubing that defines a pipe bore through the pipe segment and a fluid conduit in a tubing annulus of the pipe segment. The test head assembly includes barrier material poly welded to the tubing of the pipe segment to facilitate sealing the fluid conduit defined in the tubing annulus from environmental conditions external to the tubing of the pipe segment and a fluid port fluidly connected to the fluid conduit defined within the tubing annulus to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the fluid conduit defined in the tubing annulus via the fluid port, extracting fluid from the fluid conduit defined in the tubing annulus via the fluid port, or both.

A leak detection system includes a testing interface, which includes a rotation holder configured to retain and rotate a package. The testing interface includes a plunger apparatus configured to actuate a plunger to apply a pressure to the package before and/or during the package being inspected using a high voltage leak detection (HVLD) apparatus. The testing interface also includes a controller configured to operate and coordinate the operation of the testing interface with operation of the HVLD apparatus.

Methods and related systems for operating a climate control system for an indoor space are disclosed. In an embodiment, the method includes operating an indoor fan of the climate control system to rotate an impeller of the indoor fan in a reverse rotational direction opposite a nominal rotational direction of the impeller. Additionally, the method includes determining an airflow of the indoor fan when the impeller of the indoor fan is rotated in the reverse rotational direction. Further, the method includes determining a duct leakage rate associated with at least one duct of the climate control system based on the determined airflow, wherein the at least one duct is sealed-off at an end thereof.

A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

A drainpipe test plug for plugging a drainpipe via an opening formed therein includes a plug seal that includes a planar front surface which faces upward in the drainpipe whenever the drainpipe test plug is in a plugging position and a peripheral annular rim. The plug seal can include a plurality of holes or a continuous channel formed into the surface of the planar front surface, or a plurality of holes or a continuous channel formed into the surface of the peripheral annular rim, or both. The plug seal holes or channels impart a degree of flexibility to a peripheral area of the plug seal to facilitate the insertion and removal of the drainpipe test plug from the drainpipe. In addition, the holes or channel in the planar front surface provide additional sealing force against the interior of the drainpipe whenever the drainpipe test plug is in the plugging position.

A fitting assembly includes a fitting comprising a housing and a connector assembly arranged within the housing. The connector assembly comprising a hollow interior and configured to be movable between an unactuated position and an actuated position. In the actuated position, the connector assembly is connectable to a pipe receivable within the hollow interior. An adapter coupled to the fitting includes a biasing mechanism configured to bias the connector assembly from the actuated position to the unactuated position.

Techniques for implementing and/or operating a test head that includes an end cap assembly; a bore plug assembly including a plug fastener mechanism; an inflation fluid port and an annulus fluid port that open through the end cap assembly; and an internal inflation fluid conduit that connects the inflation fluid port to the plug fastener mechanism. The end cap assembly includes a cap end plate that covers an open end of a pipe segment, a cap sleeve to be disposed around the pipe segment, and a cap fastener mechanism that runs along an inner surface of the cap sleeve and that expands inward such that the cap fastener mechanism engages an outer surface of the pipe segment. The plug fastener mechanism is to be disposed within a pipe bore of the pipe segment and expands outward such that the plug fastener mechanism engages an inner surface of the pipe segment.
