METHOD TO DETECT RESOURCE OF PIPELINE OR VESSEL METAL Russian patent published in 2014 - IPC G01N3/00 

FIELD: instrumentation.

SUBSTANCE: method to detect resource of pipeline or vessel metal includes definition of the following: geometric and mechanical parameters of walls (energy of intercrystallite bonds between metal particles in a wall; energy of stress in the wall from action of difference between pressures of fluid and external media; consumption of energy of intercrystallite bonds between metal particles - natural ageing); main parameters of fluid medium (consumption of energy of the flow acting at wall metal; contamination of the flow with particles of abrasive material); resource of metal according to calculation formula that connects these parameters. A feature of the method is taking into account additionally defined value of metal corrosion speed and value of consumption of energy of intercrystallite bonds between metal particles from action of corrosion in calculation of metal resource.

EFFECT: increased accuracy of metal resource detection.
