Abstract
Possible causes of accelerated corrosion of elements of large-size concentrated sulphuric acid storage tanks with a capacity of up to 3000 m3, made from steel St3, are considered. Specifications and technology developed for repair of the tanks, allowing extension of their service life, are reviewed.
Keywords: arc welding, repair of process equipment, carbon steels, welded joints, corrosion, quality inspection, extension of life
