A device and method for the visual inspection of the existence of pressure within a branch line of pipe is described. A mechanical tee includes a collar portion configured to extend around a pipe. The collar portion defines an axis and includes one or more fasteners to secure the tee to the pipe. A neck portion is coupled to the collar portion. The channel of the neck portion is in fluid communication with the interior of the pipe. A seal is used to prevent leakage between the pipe and the mechanical tee. A pressure indicating device is in fluid communication with the channel of the neck portion and configured to provide a visual indication of the pressure level in the channel. The pressure indicating device may optionally include electrical contacts to communicate with a monitoring system to discern and track the pressure levels in the channel.

A retractable fitting with a stopcock has a stopcock housing for connection to a pipe or process chamber. The housing has a connection opening into the pipe or process chamber. A shut-off body is rotatable about a pivot axis relative to the stopcock housing, and has a passage hole that merges in an open state of the stopcock into the connection opening of the stopcock housing, the connection opening being closed by the shut-off body in a closed state. A support element in the passage hole is introduced in the open state through the connection opening into the pipe or process chamber. A plurality of flushing lines are operable to conduct a flushing medium, the plurality of flushing lines being accessible from outside of the stopcock and being connected to and/or opening into the passage hole of the shut-off body at least in the closed state of the stopcock.

An elbow screw joint system for screw-connecting and rerouting elongate shaped parts includes a guiding body, an insert and a cover. The insert has a guiding section rotatably arranged at least partially inside the guiding body. The guiding body has a guiding recess and an outlet recess. The guiding recess has a guiding axis and extends along the guiding axis from a receiving side to an opposite head side. The outlet recess has an outlet axis and extends from an outlet side, along the outlet axis, to the guiding recess. Also, the guiding axis and the outlet axis are at an angle relative to one another. The guiding section has a screw thread at an upper end region which is associated with the head side of the guiding body, and the cover is screw-connected, from the head side, to the screw thread of the guiding section.

An apparatus and method for puncturing a pipe in-situ is presently disclosed. The apparatus has an actuator in communication with a remote controller. A firing assembly has a firing chamber and a firing pin, wherein the firing pin is in communication with the actuator. The firing chamber is configured to hold and fire a bullet radially toward the pipe, upon the firing pin being actuated with the actuator. The method includes the steps of inserting a pipe puncturing apparatus into a pipe, activating an actuator, communicating the activation of the actuator to a hammer and moving a firing pin in the hammer to impinge a cartridge and fire a bullet.

A pig trap of this disclosure may include one or more injectors or nozzles located along a sidewall of the barrel and oriented to deliver a jet of fluid toward a back side of a vertical member of a pig or tool. The nozzle may be part of an assembly that includes a longitudinally extending pipe having a flat-profile flange at an inlet end, a curved-profile flange at the nozzle end, and a bend in between the two ends. When the assembly is installed in a sidewall opening of a pig trap, the nozzle delivers a jet of fluid toward the back side of a vertical member of the pig. A leak path may be provided through flanges or formed between the sidewall opening and a periphery of the curved-profile flange. Launch forces of more than 10 to 15 times that of a conventional launcher may be achieved.

An internal boss can have an outer side surface shaped to match the bored opening of the Drain, Waste, and Vent (DWV) pipe, an inner side surface shaped to align with an interior pipe surface of the sanitary Tee or Wye fitting component, and an internal face surface of the boss extending between the side surfaces and shaped to align with an interior pipe surface of the DWV pipe when welded thereto. Snap-fit wings can hold the interior face surface of the sanitary Tee or Wye fitting component against an exterior face surface of the DWV pipe while the fitting component and DWV pipe are homogeneously weldable into a single DWV fitting using a solvent mixture including a common plastic material. Related methods and single homogeneous fittings are also provided.

A method and system of high speed radio frequency communication between an outside of a metallic pipeline or vessel and an interior volume contained by the metallic pipeline or vessel includes passing a high speed radio frequency signal through a communication portal having a high speed radio frequency permittive material exposed to the interior volume of the metallic pipeline and to the outside. The high speed radio frequency signal may be transmitted from the interior volume to the outside or from the outside to the interior volume. The communication portal may be a cylindrical- or planar-shaped body connected to the metallic pipeline. A tool located within the interior volume may transmit, receive, or transmit and receive the high speed radio frequency signal. The high speed radio frequency signal may be configured according to a 2.45 GHz standard protocol.

An oxygen generator outlet manifold assembly that includes an outlet manifold and an end cover. The outlet manifold includes a main body portion with inner and outer surfaces and at least a first hose connector that includes an outlet defined therein extending from the main body portion. The main body portion defines a main body portion interior that includes a connection opening defined in the inner surface, a ring chamber, a flow space and a distribution chamber. An annular ring is positioned in the main body portion chamber interior and separates the ring chamber from the distribution chamber. The end cover includes a generator outlet portion extending therefrom that is received in the connection opening. The generator outlet portion includes an outlet valve having an open and a closed state and includes an interior chamber that cooperates with the ring chamber to define an outlet chamber. An oxygen flow path is defined through the open valve, to the outlet chamber, through the flow space, through the distribution chamber and to the outlet of the first hose connector.

A drain configured to evacuate leaks of fluid, such as fuel, from a leak collecting system of an aircraft, the drain comprising a rigid tube secured to a plate, the plate being configured to be attached to an external wall of the aircraft, a flexible pipe configured to join the collecting system to the rigid tube, one end of the flexible pipe being received within the rigid tube. The rigid tube comprises a channel, the channel being configured to allow separation of the rigid tube from the plate at the location of the channel.
