Изобретение относится к области трубопроводного транспорта, в первую очередь для жидких коррозионностойких сред, а также к соединению стальных труб с противокоррозионными покрытиями. Предлагаемое техническое решение позволяет решить задачу соединения труб, в частности тонкостенных и с противокоррозионными покрытиями внутренней поверхности, работающих при давлении транспортируемой среды до 16 кгс/см2 и более без деформирования торцов труб. Поставленная цель достигается за счет того, что в разъемном устройстве для соединения труб, включающем муфту с резьбой, стяжные кольца с резьбами и кольцевые прокладки, содержатся предохранительные шайбы, а муфта выполнена с упорным буртиком. Кроме того, внутренняя поверхность муфты выполнена с протекторным покрытием.The invention relates to the field of pipeline transport, primarily for liquid corrosion-resistant environments, as well as to the connection of steel pipes with anti-corrosion coatings. The proposed solution allows to solve the problem of connecting pipes, in particular thin-walled and with anti-corrosive coatings of the inner surface, operating at a pressure of the transported medium up to 16 kgf / cm 2 or more without deforming the ends of the pipes. This goal is achieved due to the fact that the detachable device for connecting pipes, which includes a threaded coupling, clamping rings with threads and annular gaskets, contains safety washers, and the coupling is made with a thrust collar. In addition, the inner surface of the coupling is made with a tread coating.
