Another problem associated with water chemistry and water-side deposits is the corro- sion of the tube. A common corrosion problem is the pitting of tubes due to the ingress of oxygen into the boiler water. The oxygen tends to attack welds and backing rings preferen- tially and can lead to eventual failure. In addition there are two major types
