Tube Failures in High Pressure Boilers - Bright Hub

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.

A more likely cause of premature failure is the slow increase in tube-metal temperatures due to the formation of the steam-side scale. Steam reacts with steel to form iron oxide along the ID surface of the tube. The microstructures themselves will show the grain-boundary sliding and the resultant creep cracks or …

Jul 20, 2018· Pipe and HRS plate are NOT the material to build a boiler, unless the pipe is something like oil well casing which has the same specification / inspection requirements as boiler tubing (I worked for an oil company for 10 years and know this from experience). You need to get certified material that is OK for Pressure Vessel application.

Even short-term contamination of the boiler feedwater may lead to corrosion-induced failures within weeks or months, particularly if a boiler system is dirty. Some WHB only recover waste heat, for example from a flue gas convection pass. In such a case, an unscheduled outage caused by a tube leak may not be a critical problem.

Finding the Root Cause of Boiler Tube Failur

Finding the Root Cause of Boiler Tube Failures

Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure.
