ANNOTATION
Gas air coolers (GAC) have been investigated. The used method of acoustic emission (AE) showed the most complete and direct information on the development (degree of danger) of defects in the material of the operated objects. AE control can be used as a determinant for the development of criteria for the state of various structures and admission to further operation of industrial facilities (while ensuring the necessary level of safety during their operation), since with AE control a defect can be detected at an early stage of development. When applying the AE method in order to develop a technology for monitoring specific objects, complex issues related to the phenomenon of the formation of elastic waves from developing cracks and the transformation of elastic waves during propagation from cracks to sensors have been resolved. The minimum permissible values of the thickness of the elements were selected according to the methodology for determining the residual resource of gas GAC operated at compressor stations of RAO Gazprom and calculation according to SNiP 2.05.06-85. A defect was found in the lower circumferential weld of the GAC gas in one (st. No.201), other defects in the metal of welded joints of the inspected GAC devices, which impede their further operation, were not revealed. The conclusion about the possibility of further operation of the apparatus was made based on the results of the inspection of the GAC gas by the AE method.
