Abstract

Резьбовое соединение двух металлических труб, согласно изобретению, включает на внешнем элементе внешнюю коническую резьбу (3) с трапецеидальными выступами и на внутреннем элементе сопряженную внутреннюю резьбу (4). Ширина (l3, l4) внешнего и внутреннего выступов (11, 12) на вершине выступа меньше, чем ширина (l1, l2) у основания выступов. Ширина вершин выступов (l3, l4) больше, чем ширина (l6, l5) сопряженных впадин. Внешний и внутренний элементы завинчиваются до положения, выходящего за предел того положения, при котором обе поверхности (13, 15) внешних выступов приходят в контакт с обеими поверхностями (14, 15) внутренних выступов. Такое соединение позволяет производить завинчивание с очень высоким моментом. Выступы одной и/или другой резьбы могут иметь или не иметь паза, выходящего на вершину выступа.Международная заявка была опубликована вместе с отчетом о международном поиске.
