Abstract: An apparatus for cleaning heat exchangers may include a cleaning lance for cleaning a plurality of bores of the heat exchanger and an examination lance for examining a plurality of bores of the heat exchanger. The apparatus may further include a first feeder configured to extend and retract the cleaning lance and a second feeder configured to extend and retract the examination lance. The apparatus may further include a controller configured to control the first feeder to feed the cleaning lance into a first bore, to control the cleaning lance to clean the first bore, and to control the first feeder to retract the cleaning lance from the first bore.

Abstract: A system, apparatus, and method of quickly inspecting tubes of chemical plants is provided, where one or more tube inspection apparatuses are used to simultaneously perform electromagnetic testing (“ET”) of multiple tubes of a chemical plant by simultaneously lowering probes into separate tubes and transmitting the data to a processor. In some embodiments, the data from the probes can be transmitted in real or near-real time to a remote processor for analysis to determine whether any defects exist in the tubes and the extent of such defects.

Abstract: A drone may be flown into proximity of a structure to measure one or more parameters of the structure. An electromagnet of the drone may be activated to electromagnetically attach the drone to the structure for inspection. A probe may be activated to inspect the structure by measuring one or more parameters of the structure.
