Abstract

Предложено усовершенствованное резьбовое соединение для соединения стальных труб, которое состоит из ниппеля, который содержит внешнюю резьбу, и муфты, которая содержит внутреннюю резьбу, при применении которого обеспечивается легкость заведения ниппеля и сопротивление заеданию резьбовых участков. Стыковочные боковые стороны профиля резьбы на участке полной резьбы одного из элементов - ниппеля или муфты - имеют двухступенчатую стыковочную форму, которая содержит фаску. Двухступенчатая стыковочная форма имеет стыковочный угол α боковой стороны профиля резьбы, который составляет 5-45°, и угол фаски β, который составляет 20-60°. Отношение h/H высоты фаски h к высоте резьбы Н нипп
