Abstract

В резьбовом соединении двух металлических труб, включающем один внешний элемент на торце первой трубы и внутренний элемент на торце второй трубы, причем внешний элемент имеет внешнюю охватываемую резьбу, внутренний элемент имеет внутреннюю охватывающую резьбу, и внешняя и внутренняя резьбы навинчиваются одна на другую, по меньшей мере, одна внешняя или одна внутренняя резьба имеет паз (61, 62), выполненный в выступе (31, 32) и выходящий или на поверхность сцепления (33, 34), или на вершину (39, 38) выступа, или на стык между поверхностью сцепления и вершиной выступа. Паз (61) выполнен в выступе (31) таким образом, что он повышает упругость части (63, 65) выступа, входящей в контакт под давлением с сопряженным выступом (32), или уменьшает площадь контактных поверхностей, или воздействует на обе данные характеристики одновременно.Международная заявка была опубликована вместе с отчетом о международном поиске.
