The invention relates to a tapping tube for a metallurgical fusion pot. The aim of the invention is to provide a tapping tube which minimises possible downtime and enables essentially identical tapping durations during the use of the tapping tube. To this end, the tapping tube functionally divides into two parts, namely a first part embodied according to prior art, and a second part that can be connected to the first part in an easily exchangeable (replaceable) manner, thus forming a complete tapping tube. According to the invention, the section of the tapping tube relating to the flow is the outlet end. The cross-section of the outlet end determines the outflow quantity and thus the outflow duration (tapping duration) of the metal melt.
