The boiler tube failures were caused by oxygen corrosion of the tubes produced by dissolved oxygen in the boiler water. This was based on the rusty appearance of most of the failed tubes, the presence of pits and tubercles (classic oxygen corrosion features) along the lengths of some of the failed tubes, and the thick oxide present on the

condition of boiler tubes also gets worse due to the wall thinning effect on the exterior walls of the tubes as it causes high hoop stress and thus, it shortens the life span of the boiler tubes. But in reality, water tube of boilers are the plane walled, due to this flow of water inside the tube is laminar.

CTL-Oxygen Corrosion of Carbon Steel Tubes in Hot Water

CAUSES OF TUBING FAILURES. Fuel ash corrosion. Fuel ash corrosion is a high-temperature phenomenon in coal and oil-fired boilers. In oil-fired boilers, sodium sulfate combines with vanadium pentoxide to form a very corrosive coating of molten "slag" on the fireside tube surface of superheater and reheater tubes.

The ASTM A179 Tubing material is to be produced by the seamless process. In addition to being seamless, these ASTM A179 Heat Exchanger Tubes have to be cold drawn as well. Because the ASTM specified A179 Boiler Tube has a lower alloying content, the cost of these low carbon steel tubes is lesser in comparison to alternate steel grades.

Localized wall thinning due to corrosion in utility boiler water-wall tubing is a significant inspection concern for boiler operators. Historically, conventional ultrasonics has been used for inspection of these tubes. This technique has proven to be very manpower and time intensive. This has resulted in a 'spot check' approach to inspections, documenting thickness measurements over a
