Compressed gas cylinders must not be heated, as they may explode. Why is there a danger of explosion

Compressed gas cylinders must not be heated, as they may explode. Why is there a danger of explosion if the gas in the cylinder is very hot?

Because when heated, all bodies expand, including gases. The average velocity of gas molecules, the average distance between them, grows, more and more often they begin to collide with the cylinder wall, which leads to an increase in pressure per unit wall area, and the cylinder can explode in the weakest point.
