Scope

Scope: This standard specifies the terms and definitions, method types, general requirements, online detection operation steps, and opening tank detection operation steps for corrosion detection and evaluation of the bottom plates of atmospheric pressure metal storage tanks, as well as recording and reporting requirements. This standard applies to the detection of the bottom plates of ferromagnetic vertical metal storage tanks on the ground, where the working medium is a liquid and the working pressure is either atmospheric pressure or less than 0.1 MPa. For non-ferromagnetic metal vertical storage tanks, this standard can be used as a reference. Main technical content: This standard provides an overview of the main detection methods, method selection, and other auxiliary detection methods for corrosion detection of the bottom plates of atmospheric pressure metal storage tanks. It specifies the requirements for detection personnel, equipment, and instruments, as well as detection process documents and safety requirements. It also stipulates the preparation before online detection, determination of detection conditions, sensor arrangement, system debugging, background noise measurement, data collection, and detection results and evaluation. It further specifies the preparation before opening tank detection, determination of detection conditions, instrument debugging, system calibration, opening tank detection methods, detection results, and evaluation. It details the minimum content that should be recorded in the detection report.
