METHOD OF EVALUATING LOSS OF TRANSPORTED GAS THROGH UNTIGHT GATE OF BALL COCK OF MULTI-PURPOSE VALVES OF MAIN LINE Russian patent published in 2009 - IPC F17D5/02 G01M3/08 G01F1/00

Abstract RU 2362088 C2

FIELD: oil and gas production.

SUBSTANCE: invention refers to gas transporting via pipelines and can be implemented for testing of multi-purpose valves of main line. The method of evaluating loss of gas consists in injecting indicator gas directly into the cavity of the valve of the multi-purpose valve system and in conditioning during certain period, whereupon concentration of indicator gas is measured in the cavity of the valve; further, on base of obtained values loss of transported gas through the untight gate and leak of tested multi-purpose valves are determined.

EFFECT: upgraded accuracy of evaluating of loss.
