Performance of periodical integrated technical inspections of steel cylindrical welded tanks of a large volume is a mandatory condition of their safe service. The main purpose of integrated technical inspection of tanks is determination of their technical condition, possibility of further safe operation, dates of subsequent inspections, need for repair or removing the tanks from service. 1. Non-destructive testing of welded joints and base metal of the tank results in revealing sections with inadmissible defects for their repair. Such sections are then repaired and re-tested. 2. Mechanical testing and metallographic analysis of samples, chemical and spectral analysis of the metal reveal deviations from the requirements to steel of certain type. 3. The tank is cleared for operation for the next period.
