PRESSURE VESSEL HISTORY MANAGEMENT APPARATUS AND ITS USING METHOD

摘要

The present invention is caused by leakage to facilitate the traceability of the pressure vessel explosion or to provide a pressure vessel filled with the history management apparatus and method capable of preventing fire in aspect The present invention relates to a history management unit of the pressure vessel in order to achieve the foregoing object, is provided on the surface of the pressure vessel and the strain gauge for measuring strain, a pressure gauge for measuring gas pressure is filled in the pressure vessel is provided, The pressure and the unique identification information of its own input-output unit that is possible to form the container, and measure the stress strain of the strain gauges is formed by the stress calculated by the input pressure from the pressure gauge-strain curve by the identification unit to the natural input pressure vessel material-specific reference stress-strain curve as compared with that is characterized in comprising a history management unit comprises a control processing unit for displaying the difference The pressure vessel history management apparatus of the present invention will be to identify the number of pre-filled through the unique identification of the pressure vessel to be sent to notify the danger to the user warning signal if it exceeds the specified number of times for each material fatigue failure. ;
