Boiler Tube Failure Investigation - TCR Advanced

Boiler tubes. can undergo sudden failures by rupture or leakage and is usually detected while in operation rather than during a hydro test or other inspection activities. This calls for immediate action as it can often cause a shutdown of the boiler, leading to loss of production and downtime. It is critical to understand the various modes and

Waste heat boilers — Sandvik Materials Technology

The Sandvik program includes composite tubes for use in waste heat boilers in metallurgical plants. Composite tubes with Sandvik 3R12 (ASTM TP304L) outer layer provide excellent protection against flue gas (for example SO 2) corrosion. Sanicro ® 28 (UNS N08028) is an even better oxide former and used for more severe conditions.
