Abstract
This paper discusses methods of nondestructive testing, the main method is method of acoustic flue gas emission. It was found that the use of this method in the diagnosis of bottom pipe and dug-in areas allows to reduce time, does not require surface dressing to a certain value, provides almost instant information about the defect at a great distance to the nearest gas-pumping station and is not inferior to the reliability of the control other existing methods.
Highlights
The emergence of modern large-scale facilities - nuclear power stations, LNG terminals with, offshore drilling rigs, large chemical plants, large airliners - led along with economic benefits to large negative consequences in the event of their failure
Control of state of the metal of dug-in areas and bottom pipe of pipeline sections are greatly complicated by the inaccessibility of objects
In-line flaw-shells are currently used for this purpose, which have more weight, high cost (≈ 4 million. rub.), on the long runs low productivity
Summary
The emergence of modern large-scale facilities - nuclear power stations, LNG terminals with, offshore drilling rigs, large chemical plants, large airliners - led along with economic benefits to large negative consequences in the event of their failure. On the above-ground parts of transceivers modules are installed on the outer surface of the pipeline, the transmission of radio signals over the air goes into the surrounding atmosphere, the power - with autonomous battery charging from solar panels.
