FIELD: testing equipment.
SUBSTANCE: invention relates to the field of nondestructive check of pipelines and may be used for their in-line inspection. Result is provided by the fact that device for pressure testing of pipeline comprises the first high pressure seal and the second high pressure seal adjusted to seal test volume arranged within the limits of pipeline section between the first and second high pressure seals, and at least one flexible element that connects the first high pressure seal to the second high pressure seal, besides at least one flexible element is adjusted to shift the first high pressure seal relative to the second high pressure seal, which provides for the possibility of device motion in pipeline bend.
EFFECT: improved performance and efficiency of pipeline tests.
