Improved life for the pumps handling molten sulphur could be obtained through
the use of sulphuric acid resistant alloys such as duriment rather than cast iron .
The hot gases from the burners are often partially cooled and transported to the ...

increased volume of the oxidation product and pressure built up in the confined
areas result in splitting the cast iron . Steel is preferred to cast iron for oleum
service . Cast iron and cast steel valves were , and still are , used for contact acid
