ABSTRACT:
Disclosed is a method of heat-treating a pipe in which cooling water is passed through the pipe while the pipe is heated from the outer side thereof, so as to create a temperature differential between the outer and the inner sides of the pipe, so that the inner side of the pipe may be tension-yielded or the outer side of the pipe may be compression-yielded, thereby to generate a compressive residual stress and a tensile residual stress at the inner and the outer sides of the pipe, respectively.
