Here the high temperature oxygen fuel gas flame causes the scale to flake
off because of the great difference in thermal expansion between it and the
underlying metal. Corrosion products and rust are decomposed by rapid dehydration and explosion of combined water to form a powder which can
easily be brushed off.
The Torch flame cleaning heads lenght 50, 100, 150, 200 mm are ideal for
cleaning, de-escaling from steel structures before painting.
