METHOD OF PIPELINE FLAW DETECTION Russian patent published in 2001 - IPC

Abstract RU 2164321 C2

FIELD: measurement technology. SUBSTANCE: method is used when testing of pipelines being built and operated. To determine pipeline flaw location, constant test pressure is preliminarily provided in cavity between pipeline starting point and circular chamber. Under the action of the pressure circular chamber is moved along pipeline at preset speed. Location and quantitative parameters of flaws are determined by value of test pressure variation. EFFECT: enhanced efficiency of flaw detection. 1 dwg
