A connector includes: a tube body formed in a tubular shape having a first opening and a second opening at both ends thereof, a first opening side of the tube body being connectable to an end of a first pipe, a second opening side of the tube body being connectable to an end of a second pipe, the tube body allowing a fluid to flow therethrough between the first opening and the second opening; a temperature detection element embedded in a tubular part of the tube body and configured to detect a temperature of the fluid flowing through the tube body; and a terminal electrically connected to the temperature detection element and exposed to outside of the tube body.

A method of leak detection for oil and gas pipeline based on excitation response and system thereof includes: applying an active excitation signal (a pressure pulse directly input by human) or a passive excitation signal (a pressure fluctuation caused by opening and closing valves, etc.) to an oil and gas pipeline with existing leakage points, the excitation signal is reflected at the pipeline boundary and the leakage, and the reflected pressure wave continues to propagate to upstream and downstream, and finally is collected by the dynamic pressure transducer, then the existing leakage of the pipeline is detected and positioned by analyzing the transient response signal and the reflected pressure wave of leakage signal.

Techniques for determining a thermal condition of a pipeline include identifying a pipeline that carries a first fluid at a first temperature that includes a tubular conduit that includes a bore that carries the first fluid, and a layer of insulation installed over the tubular conduit; circulating a second fluid at a second temperature from a bypass conduit that is fluidly coupled to the tubular conduit through the layer of insulation into the bore; based on circulating the second fluid into the bore, detecting a thermal gradient between the first fluid carried in the bore and the tubular conduit or the layer of insulation at a particular location of the pipeline; and based on the detected thermal gradient, determining a presence of at least one of water or water vapor between the tubular conduit and the layer of insulation at the particular location of the pipeline.

An improved mechanism for evaluation of degradation criticality is described. Corresponding apparatuses, systems, methods, and computer readable media are provided. The evaluation of corrosion criticality is utilized to estimate a failure pressure of a pipeline that is subject to structural degradation (e.g., metal loss corrosion). The evaluation, in some embodiments, is utilized with a specific tool configured for controlling or otherwise regulate pipeline operations responsive to the estimated failure pressure. The evaluation is a specific technical process whereby multiple failure paths through anomalies (structural defects arising from degradation features) are utilized in concert to determine an estimated failure pressure. The failure pressure, in some embodiments, is used to control actuation of one or more valve regulator features or to guide excavation.
