ABSTRACT:
In rapidly cooling a large diameter metal pipe for quenching purposes, the essential requirements for ensuring uniform cooling of the pipe, namely, the jet velocity and the dip angle and transverse angle of jets of the cooling water directed against the surface of the pipe from a large number of spray nozzles contained in each of a first and second ring header encircling the pipe, and the distance between the circumferential line defined on the pipe by connecting the points of impingement onto the pipe surface of the water jets sprayed in the direction of the second header from the spray nozzles of the first header and the similar circumferential line defined on the pipe by connecting the points of impingement onto the pipe surface of the water jets sprayed in the direction of the first header from the spray nozzles of the rear second header, are specified with numerical values.
