Abstract
An assembly includes a discharge member of a metallurgical vessel and a pipe member connected to the discharge member at mutual surfaces thereof defining a seat therebetween. An annular recess is formed in the region of such seat, a seal seals such seat, and gas is supplied to the annular recess. The seal is in the form of a pair of compressible sealing rings positioned between the mutual surfaces of the two members on opposite sides of the annular recess. A pressure indicator is connected to a gas supply line supplying gas to the annular recess to provide an indication of the pressure of gas prevailing in the annular recess, and particularly of changes of such pressure.
