ABSTRACT:
Heat is removed from, or supplied to, a vertical pipe of any cross-section, whose internal temperature is above or below the ambient temperature and whose wall temperature must neither exceed nor fall below a predetermined temperature range, by a method in which, in order to maintain the predetermined temperature range, the pipe is provided with a coaxial sheath and gas is passed through the gap between the pipe and the sheath. The invention is particularly directed to maintaining a predetermined temperature range at the outer pipe wall of the vertically oriented, double walled pipes which connect the reaction sections with the collectors in a steam reformer.
