Abstract

Изобретение относится к контролю газопроводящих трубопроводов с помощью ультразвука при наличии контактной жидкости, перемещаемой совместно с устройством для контроля газопроводящих трубопроводов. Устройство содержит носитель для чувствительных элементов и связанный с ним носитель для скребковых манжет, ограничивающих зону перед носителем чувствительных элементов и зону чувствительных элементов, причем эти зоны соединены трубопроводом с насосом. Особенность способа контроля заключается в создании избыточного давления в зоне чувствительных элементов, что позволяет снизить необходимое количество контактной жидкости.
