NOVELTY - The utility model claims a graphene-Zr-MOF- polydimethylsiloxane anti-corrosion coating detecting device, comprising an annular detecting device main body for detecting pipe outer layer graphene-Zr-MOF- polydimethylsiloxane composite coating corrosion resistance, the detecting device main body is detachably connected with multiple semi-annular metal hanging sheets with different widths, the metal hanging sheet is concentrically arranged with the detecting device main body, the plane of the metal hanging sheet side end surface is provided with a groove for representing the width of the metal hanging sheet. The utility model is provided with a groove for marking the width of the metal hanging sheet on the metal hanging sheet, the metal hanging sheet with different widths can be selected according to different detection working conditions to improve the applicability of the device, and because the mark groove can be used to quickly obtain the width data of the metal hanging sheet so as to obtain the corresponding detecting condition, reducing the manual checking multiple different metal hanging sheet corresponding to the detection working condition after the corrosion detection.
