Abstract

Резьбовое соединение состоит из ниппеля (10) и приемной части (20). Ниппель (10) включает, по порядку в направлении от его конца, поверхность (11) буртика, носовую область (12), первую уплотняющую поверхность (13), первую охватываемую резьбовую область (14), кольцевую область (15а), вторую уплотняющую поверхность (16) и вторую охватываемую резьбовую область (17). Приемная часть (20) включает поверхность (21) буртика, углубленную область (22), первую уплотняющую поверхность (23), первую охватывающую резьбовую область (24), кольцевую область (25а), вторую уплотняющую поверхность (26) и вторую охватывающую резьбовую область (27). В резьбовом соединении в скрепленном состоянии поверхности (11, 21) буртиков находятся в контакте друг с другом, первые уплотняющие поверхности (13, 23) находятся в контакте друг с другом, вторые уплотняющие поверхности (16, 26) находятся в контакте друг с другом, между носовой областью (12) и углубленной областью (22) обеспечен зазор, между кольцевыми областями (15а, 25а) обеспечен зазор, первая охватываемая резьбовая область (14) сопряжена с первой охватывающей резьбовой областью (24), и вторая охватываемая резьбовая область (17) сопряжена со второй охватывающей резьбовой областью (27).
