ГОСТ 17376-2001 Тройники
Тройник – деталь, используемая для присоединения к магистральному трубопроводу боковых ответвлений. В зависимости от отношения диаметров корпуса и горловины различают переходные и равнопроходные тройники.
Переходные тройники имеют разные диаметры проходных отверстий корпуса и горловины и используются для ответвления трубопровода меньшего диаметра от продольной оси основной магистрали.
