A storage tank with insulation layer that has been in service for 17 years was found to have extensive corrosion on the tank wall after removing the insulation layer.Conventional corrosion thickness measurement methods cannot carry out corrosion detection work.This article uses a crawling robot equipped with a pulse eddy current probe to conduct C-scan wall thickness measurement of storage tanks,effectively obtaining the corrosion thinning situation of the storage tanks.The thickness reduction of the surface storage tank wall did not exceed the corrosion allowance,and it can continue to be used after anti-corrosion maintenance.
