In the method of heat-treating a metal tube, the metal tube (1) accommodated in the heat treatment, by carrying out the longitudinal direction placed on a beam 22 disposed release plurality stretched at an interval of 200 ~ 2500mm heat treatment, the coloring of the metal tube, and without causing the deterioration of the production efficiency, it is possible to suppress the bending of the metal tube and friction inclusions. When mounting the metal tube (1) on the beam 22, by interposing a spacer is notahdo up the metal tube (1) on the beam (22). The heat-treating process of the metal tube of the present invention, it may be desirable, and further suppress the frictional flaw by using a spacer which has a beam or convex shape having a top surface of convex shape.
