BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas pipe joint crack detection device using a self-healing coating agent containing a photochromic dye, wherein a coating agent containing a self-healing material and a photochromic dye in a capsule is applied to a crack or a pipe joint of a pipe. In the case of pipe cracks, the primary crack closure is made through self-healing materials, and the photochromic dye is exposed to the outside so that the user can easily detect cracks and crack locations due to color change. It relates to a gas pipe joint crack detection device using a self-healing coating comprising a photochromic dye.
