Nondestructive Test Equipment for Wire Rope

摘要

Nondestructive test equipment for inspecting steel wire ropes was evaluated in laboratory and field tests. Individual AC/DC units and a unitized AC/DC unit were tested on wire rope to detect broken wires and loss of metallic area from wear and corrosion. The unitized AC/DC units used Hall effect sensors to pick up the defects as opposed to sensor coils used in the individual AC/DC units. The Hall effect sensors enabled less equipment to be used to conduct a complete inspection and also permitted the wire rope to be inspected at speeds from 0 - 500 fpm. It is recommended that Navy facilities requiring nondestructive test inspection capability for metallic wire rope inspection procure the unitized AC/DC unit. (Author)
