A method of managing a fluid flow within a conduit includes determining a presence of a flow blockage within the conduit, the conduit being equipped with an expandable device, controlling a fluidic actuator to deliver an actuation fluid to the expandable device to expand the expandable device radially, compacting the flow blockage radially along a length of the expandable device to create a channel adjacent the flow blockage, controlling the fluidic actuator to withdraw actuation fluid from the expandable device to collapse the expandable device radially, and exposing the channel to open the conduit to fluid flow.

A pipe erroneous assembly preventing structure includes a pipe and a case. The pipe includes a stay in which a stay-side abutting portion and a stay claw portion intersect with each other in an L shape. The case includes a hole forming portion; a first protrusion portion provided in the hole forming portion; a case-side abutting portion which is recessed in the first protrusion portion and to which the stay-side abutting portion of the stay abuts, and a second protrusion portion protruding from the case wall surface. In a case where a length of the stay claw portion in the insertion direction is set to Ls, a distance from the case wall surface to the case-side abutting portion is set to Lg, and a distance from the case wall surface to the second protrusion portion is set to Lp, Lg−Lp<Ls≤Lg is satisfied.

A connection verifier for engaging a fluid connection including a tube end form, a fluid connector, and a snap ring having one or more protrusions, the connection verifier comprising a boot including an aperture, and a probe having a leading edge operatively arranged to engage the snap ring, and a circuit arranged in the aperture, the circuit operatively arranged to detect one or more forces applied to the leading edge, wherein the connection verifier is operatively arranged to determine if the fluid connection is properly connected based on the one or more forces applied to the leading edge.

A quick connect fitting for coupling a first component of an evaporative emissions system of a vehicle to a second component of the evaporative emissions system is provided. In one example, the quick connect fitting includes an indicator section that includes a color-changing material that changes color based on an extent of deformation of the color-changing material, where secure coupling of the first component to the second component is dependent on the extent of deformation. In this way, it may be readily determined as to whether a particular quick connect fitting is securely connected, which may improve engine operation, reduce undesired emissions, and reduce warranty rates.

A proofing air jet having a hollow elongated body having an air outlet and a suction inlet, the air outlet opposing the suction inlet, a pressurized air inlet into the body between the air outlet and the suction inlet, the pressurized air inlet being angled with respect to the hollow elongated body to flow pressurized air in a direction from the pressurized air inlet to the air outlet and provide a suction at the suction inlet, the air outlet having an innerduct/microduct connector for connecting to an opening of the innerduct/microduct, and the suction inlet having a string inlet configured to accept string, and the method further comprising blowing air through the pressurized air inlet into the hollow elongated body and into the innerduct/microduct, wherein the air sucks the string through the string inlet and carries the string through the hollow elongated body and through the innerduct/microduct. A plurality of the proofing air jets can be connected to a manifold. A method of proofing an innerduct/microduct using the proofing air jet to blow a string through the innerduct/microduct.

A corrosion detection system includes a wire disposed in a groove extending circumferentially around an exterior surface of a pipe, the pipe comprising a pipe wall and a pipe liner that lines an inside surface of the pipe wall. The corrosion detection system also includes a sensor electrically coupled to the wire. The sensor is configured to generate a voltage in the wire, and detect a change in a property of the wire caused by exposure of the wire to a corrosive fluid that is present within the pipe but outside the pipe liner.
