Girth Gear Inspection Deliverables: We provide a complete non-destructive examination of the integrity of the mill gear teeth in accordance with ASTM E2905, for macro-pitting and cracking. We analysis the data as we scan the teeth. If cracks are detected, we provide remedial relief (excavating services) during the inspection site visit.
