SOME EXAMPLES OF CORROSION IN STEAM PLANT Available to Purchase

The inspection of steam plant by Engineer Surveyors, either in accordance with statutory regulations when out of service, under working conditions, or at times of trouble, often reveals instances of corrosion. In the past, pitting and corrosion was a regular feature in practically all shell boilers, and not uncommon in watertube boilers, but in recent times this has become comparatively rare. This in itself is a tribute to the realisation, with the advent of the package boiler, of the necessity for boiler feedwater treatment and the maintenance of satisfactory conditions in boiler water in the lower pressure range.
