Abstract
A carbon monoxide containing gas mixture at a temperature of 500.degree. C. is conducted through the inner protective tubing of a sheath tube lined with a thermally insulating protecting composition. The inner tubing is divided into sections and a potentially CO-free mass is introduced in the sheath tube in the regions of the thermally insulating mass to permeate the latter and form a barrier between the carbon monoxide gas and sheath tube, thereby eliminating hot spots and metal dusting corrosion.
