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.

A flaw detection system may include a dedicated monitor volume within a structural component of a system. The monitor volume may establish an air tight space bounded by at least one joint where the joint establishes a portion of a boundary of the air tight space and is in fluid communication with the air tight space. The system may also include a pressure sensing device configured for sensing the pressure in the dedicated monitor volume. A method of monitoring a system for flaw development may include monitoring a pressure sensor configured to sense the pressure in a dedicated monitor volume of a structural component of a system. The method may also include inspecting the structural component to identify a flaw location when the pressure sensor identifies a change in pressure in the dedicated monitor volume.

A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position. Flow through the testing device is allowed with the rotary valve closed and the tubular valve stem in an open position. With the rotary valve open, flow through the tubular valve stem is permitted when the tubular valve stem is in either the first or second position to provide multiple drain and fill options.

The present teachings relate to a blood purification apparatus in which the connection of a substitution line to a collecting port can be checked accurately and instantly and even during blood purification treatment. A blood purification apparatus includes a blood circuit, a dialyzer, a dialysate introduction line, a dialysate drain line, a substitution line one end of which is connected to a collecting port provided at a predetermined position of the dialysate introduction line and an other end of which is connected to the blood circuit, a substitution pump configured to form a pressure-increasing portion that includes the collecting port, and a pressure-measuring device capable of measuring a pressure in the pressure-increasing portion. The blood purification apparatus performs a testing process by increasing a liquid pressure in the pressure-increasing portion by utilizing a liquid-feeding pressure applied from a liquid-feeding device and measuring the pressure with the pressure-measuring device.

The method of providing a connector suited for quickly connecting and testing joints of pipe for a subsea pipeline and similar applications by concurrently locking, preloading, sealing and testing of the connection to eliminate the usual sequential time requirements for each of these operations. Additionally, time for coating and X-Ray inspection of the welded connection in critical path time are eliminated as the welding and coating operations are able to be done on shore in non-critical path time.

A testing system for testing high pressure fluid control products includes a testing chamber having a testing configuration in which an access door is in a closed position and contents of the testing chamber are contained for testing. The testing chamber includes a designated fitting testing area and a designated pipe testing area in fluid communication via an access window. The testing system also includes a set of interchangeable quick connect fixtures having similarly sized base ends and differently sized attachment ends. The designated fitting testing area includes a fitting test bench supporting at least one quick connect fixture for testing high pressure fittings, and the designated pipe testing area includes a pipe test bench supporting at least one quick connect fixture for testing high pressure pipes.

A method and system for detecting small leaks in a plumbing system is disclosed. A temperature sensor coupled to the water in the plumbing system is used to determine if there is a leak. During times of inactivity for fixtures in the plumbing systems, a flow sensor might measure usage of water that would indicate a leak. For very small leaks, the flow is below a minimum measurable flow of the flow sensor. Embodiments of the invention measure temperature of water within a pipe coupled to the plumbing system. Temperature will generally decay in a particular predicable way when there is flow as the temperature of water upon entry to the building is lower than the air temperature within the building. Signal processing, machine learning and/or statistical approaches are used to analyze the temperature and optionally flow and/or pressure over time to determine when a leak is likely.

A bundle section (20) of a subsea pipeline bundle comprises a rigid carrier pipe (12) having an end closed by a transverse bulkhead (26A, 26B), and one or more fluid conduits in fluid communication with an opening that penetrates the bulkhead. Fluid coupling formations such as a spigot or a recess on an outer face of the bulkhead surround the opening. Leak-tight coupling between successive fluid conduits is effected when the bulkheads of two such bundle sections are brought together. This forces together opposed complementary fluid coupling formations of the bulkheads. The bulkheads connect the adjoining bundles sections fluidly and mechanically.
