Abstract
A process for heating at least two metal pipes wherein each pipe is individually preheated in response to sensors detecting its initial temperature and wall thickness. The pipe then passes through a continuous heater which applies an equal amount of energy to each portion of the pipe, after which each pipe emerges having a predetermined temperature independent of both its initial temperature and the wall thickness.
