FIELD: machine building.
SUBSTANCE: during test for leakage of isolation valve of linear part of main oil pipeline, during which pressure is created in oil pipeline by lattice diagram, the highest pressure is created in the left and then in the right end sections, pressure differentials are made equal to static pressure subject to longitudinal profile of oil pipeline, and as a working agent for test pressure creation pumpage is used.
EFFECT: higher test accuracy.
