This paper describes that when the accumulation of oxide scale in boiler tubes reaches a certain level under long-term exposure to high temperature, high pressure, and steam, it can lead to partial blockage of the tubes and cause tube explosion accidents. A field-applicable oxide scale detection instrument based on the far-field magnetostatic method has been developed to address the difficulty of quantitatively detecting oxide scales in weakly ferromagnetic boiler tubes using existing magnetic non-destructive testing methods. This paper introduces the instrument’s composition, the implementation of software functions, and the operation mode, and conducts field experimental verification.
