Переход ГОСТ 17378-2001 является типом арматуры соединительного характера. Он применяется, чтобы изменить диаметр трубы, при этом трубопровод должен быть расположен исключительно горизонтально. Важно отметить, что соединяются трубы по нижней линии образующего характера.
В основе перехода эксцентрического лежит сталь разных марок. Выбор стали зависит от нескольких параметров переправляемых веществ (например, скорость). Для перехода характерна работа при температуре до 450 градусов и при рабочем давлении не выше 16,0 Мпа.
