ECT System for Steel Pipe End (Type L)

This eddy current testing system automatically detects longitudinal harmful flaw on the zone of approx. 300 mm from both end of steel pipe, where used be dead zone for inspection, while pipe is turning. If a harmful flaw is detected on a pipe end, NG marking is done on the designated position of the pipe. This system is also applicable for inspection of round steel billet, round bar and nonferrous materials.
