An apparatus for detecting a puncture comprises a housing comprising a plurality of compartments. Each compartment comprises an opening for receiving a flow of air into the compartment. Each compartment also comprises a detection element mounted on an axle, the axle having a first end and a second end and being secured at said first end and said second end within the compartment. The detection element is rotatable about the axle and when a flow of air passes through the opening into the compartment, the detection element rotates around the axle in response to the flow of air.

Techniques for implementing and/or operating a testing system that includes a pipe segment, which includes tubing having an inner layer that defines a pipe bore, an intermediate layer including electrically conductive material implemented around the inner layer, and an outer layer implemented around the intermediate layer, and a return wire embedded within the tubing. The testing system includes a signal generator that supplies an electrical test signal to the electrically conductive material, a sensor electrically coupled to the return wire, in which the sensor determines a sensor signal indicative of an actual electrical return signal received from the return wire in response to supply of the electrical test signal, and a control sub-system communicatively coupled to the signal generator and the sensor, in which the control sub-system determines an integrity state of a pipeline in which the pipe segment is deployed based at least in part on the sensor signal.

A thermowell assembly for use in measuring a temperature of a process fluid includes an elongate thermowell body configured to mount to a process vessel and extend into the process fluid. An elongate bore extends along a length of the thermowell body from a proximal end of the thermowell body proximate a wall of the process vessel to a sealed distal end of the thermowell body positioned in the process fluid. A side bore extends from an exterior of the thermowell assembly to the elongate bore. The side bore is positioned outside of the process vessel. A verification valve includes an inlet coupled to the side bore at the exterior of the thermowell assembly and further includes an outlet.

A leak test apparatus including a sleeve member having a first end and a second end and being configured to surround a portion of a transmission medium, a first retaining device configured to couple the first end of the sleeve member to a boundary fitting to which the transmission medium is coupled, and where the sleeve member is configured to contain a leak detection medium and effect a pressurization of the boundary fitting with the leak detection medium.

A tub drain overflow test system employs a kit with a connecting pipe with a front cylindrical portion having an inner threading and an intermediate annular flange coaxial with the front cylindrical portion. The front cylindrical portion extends through an overflow hole of a tub so that the annular flange, optionally with a seal ring, abuts the rear surface of the tub wall. A test cap has outer threading that mates with inner threading of the front cylindrical portion. The test cap has an annular flange and a breakaway test seal with a projecting grip tab. The test cap has an inner lip that provides a catch for inwardly extending tabs on a fixture to attach. The test cap allows the overflow drain to be tested. A seal portion is removed to provide access to the opening and the finishing fixture is mounted in place.

A coupling for use with a blower unit for detecting leaks in a structure, wherein the coupling is constructed and arranged to attach to a surface of the structure defining an opening and to the blower unit, and to allow air flow through the coupling when the blower unit is attached to the coupling and to prevent air flow through the coupling when the blower unit is not attached to the coupling, and wherein the coupling further includes a pressure port defined within a surface of the coupling constructed and arranged to accommodate at least one of a differential pressure gauge fitting or a tube.
