Owing to protect the inside bottom steel plate in the oil strage tank, coating tank by resin increase.
The non-destractive inspection system on the coating film has been developed,
1. Measurement method of bottom steel plate thickness by ultrasonic thickness gage.
2. Detecting method of the surface flaw on the weld parts by creeping wave ultrasonic testing, eddy current testing, and magnetic flux leakage testing.
