The number of explosions and failures in steam tubes of ovens remains extremely high, and measures for a reduction of this number are overdue. The lack of safety controls is the main reason for the majority of these accidents, and it is usual, following an explosion, to state that the tube was ‘overheated’. Experimental results or data on metal temperatures on enclosed steam tubes do not appear available, and this paper embodies experimental results in this direction. A great deal of further research is necessary and should be carried out.
