The austenitic stainless steel surfacing layer on the inner
wall of hydrogenation reactor is prone to crack and spread to the matrix. Magnetic powder can not
be operated, penetration can only detect surface opening defects, and can not
evaluate the depth of crack growth, and grinding dust in closed space greatly
damages detection personnel. FGI-3D technology
is the best detection method, which can quickly scan the cracks on the surface
and near the surface of the surfacing layer without grinding and can also
evaluate the depth and length of the cracks.
