ABSTRACT:
A method and apparatus for cooling at least the inside of steel pipes. Cooling is effected while restraining the radial displacement of a pipe at a point not more than 500 mm, or preferably not more than 250 mm, away from each end of the pipe and at intermediate points spaced at intervals of 1.0 m to 2.5 m. Elliptical deformation in the cross section of larger-diameter pipes also is prevented by adding to the aforementioned cooling method and apparatus a device and step to rotate the pipe being cooled at a rate of 30 to 150 times per minute. The restraining device at one end of the pipe is designed to move in the direction of the pipe axis so that the restraint of the radial displacement at a point not more than 500 mm away from that end is at all times ensured even when the pipe length varies.
