This allows to modify efficiently the tool design meeting the field conditions of its operation, resulting positively in increase of its total and overhaul life.

As the result of the equipment revision, service personnel prepares defect tally sheet containing the list of parts requiring replacement and repair. During every revision, non-destructive testing of all main assemblies and parts is provided. The defect tally sheet is submitted to customer for approval, if required the sheet includes photos on revealed nonconformities and breakdowns. The reasons of all breakdowns are determined. In complicated situations we make request to specialized labs of nondestructive testing for the information on possible reasons of breakdown/failure of the parts on molecular level.
