Abstract

The invention discloses an anti-corrosion detection technology for a petroleum mechanical device. The corrosion degree of the mechanical device is reduced through application of technical means, global thinning is performed on a globally corroded device, and global processing of the device is performed through modes of visual inspection or ultrasonic thickness measurement etc.; local thinning is performed on a locally corroded device, local corrosion phenomena usually comprise crevice corrosion and pitting corrosion, and the corrosion can be effectively processed through potential detection orfluorescent powder detection; the petroleum mechanical device also has a phenomenon of sensitization or hydrogen embrittlement which can be detected through a sampling analysis, and conventional monitoring equipment comprises hydrogen flux measurement and eddy-current test devices; and most corrosion problems in the device are stripping and blistering, and the detection efficiency can be improvedby employing modes of radiographic testing and ultrasonic angle beam testing etc. Through the above technical scheme, a certain assistance effect for staff can be produced during detection.

Description

technical field [0001] The invention relates to the detection field, in particular to a petroleum machinery equipment anticorrosion detection technology. Background technique [0002] The machinery and equipment of petroleum enterprises belong to the fixed assets of the enterprise. However, petroleum enterprises have certain particularities, mainly in the exploitation of petroleum resources. Require. The exploitation of petroleum resources requires the operation of mechanical equipment to achieve work goals. During this process, petroleum machinery and equipment will be subject to varying degrees of corrosion in petroleum hydrates due to the influence of the working environment. And the degree of corrosion will continue to increase with the increase in the frequency of oil and gas collection by petroleum machinery. If the petroleum machinery and equipment are severely corroded, it will directly affect the normal operation of petroleum companies. Contents of the invention ...
