Abstract

Изобретение относится к трубе для термического разложения углеводородов в присутствии пара, при котором обрабатываемая смесь пропускается через нагреваемые снаружи трубы, причем труба простирается вдоль продольной оси и имеет число Nжелобков, сформированных во внутренней поверхности трубы, спиралеобразно проходящих вокруг продольной оси вдоль внутренней поверхности, внутренняя поверхность, в которой были сформированы желобки, в поперечном сечении перпендикулярно продольной оси имеет диаметр Di и радиус r=Di/2, желобки в поперечном сечении перпендикулярно продольной оси в своем дне желобков соответственно имеют форму дуги окружности, и дуга окружности имеет радиус r, и желобки соответственно имеют глубину ТТ желобков, которая соответствует кратчайшему расстоянию в поперечном сечении перпендикулярно продольной оси между окружностью с диаметром Di, в которой находится внутренняя поверхность и ее срединная точка находится на продольной оси, и самой отдаленной от продольной оси точкой дна желобка.
