METHOD OF DETERMINING OPERATION LIFE OF METAL OF PIPELINE OR VESSEL Russian patent published in 2007 - IPC G01N3/12

Abstract RU 2297618 C2

FIELD: investigating or analyzing materials.

SUBSTANCE: method comprises determining basic mechanical and geometrical parameters of the object to be investigated (yield point, inner and outer diameters, wall thickness), basic parameters of fluid (flow rate, pressure and temperature at the inlet and outlet of the pipeline or vessel, angle of inflow, admixture concentration), and determining operation life of metal of pipeline or vessel body from the formula presented.

EFFECT: enhanced reliability.
