Analysis of Hardware Implementation of Far-field Static Magnetic Detection Technology for Oxide Scale Blockage
This paper expounds that when boiler tubes are exposed to high temperature,high pressure,and steam for a long time,when the accumulation of oxide skin reaches a certain level,it can lead to local blockage of the pipeline and cause pipe explosion accidents.It faces the challenge of quantitative detection of oxide scale inside weakly ferromagnetic boiler tubes using existing magnetic non-destructive testing methods,and develops an oxide scale detection instrument based on far-field static magnetic method that can be applied in the field.It introduces the composition of the instrument,implementation of software functions,and operation methods,and conducts on-site experimental verification.
