The roller track for moving large pipes through a tempering furnace includes two pairs of relatively closely spaced, resiliently mounted rollers disposed in the end zone of the furnace, where any portion of the pipe passing through is hot and has minimum strength on account of the heating.

Roller track for pipes

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.
