Abstract
Concave rails 17, upon which a pipe which is to be treated by at least partial immersion can be placed, are fixed in the bottom of a furnace 1 which contains a treatment bath M. In order to guarantee that the pipe is immersed over the whole of its cross section and in order to eliminate the risk of it becoming oval, the furnace is subjected to alternating rotation about its axis XX, which compels the pipe to turn on itself by rolling on the rails 17. The handling of the pipe is achieved by arms 12 which are assembled in a pivoting manner on the external wall of the furnace and controlled by an actuator 15.
