Abstract

PURPOSE:In heating, hardening and tempering a steel pipe of larger diameter, e.g., 16 to 20 inches diameter, which is used for the transportation of oil or the like at a cold district, it is intended to prevent deformation of the steel pipe during hardening and tempering by placing constraint rolls on the inlet and outlet side.
