Failure investigation of water wall tubes in a drum boiler

Dec 01, 2020 · This cycle is repeated continuously. The steam generated by this cycle is in the superheated phase at a flow rate of 550 t/h, 540 °C and a pressure of 120 bar, which feeds a 145 MW steam turbine. In the studied boiler, the diameter and wall thickness of the riser tubes were 63.5 and 4.87 mm, respectively.

Best Practices For Expanding Water-Tube Boiler Tubes

Boiler expanders are designed with rolls sufficiently long to roll 1/4 to 3/8 beyond the sheet thickness. Boiler inspectors insist that tubes be rolled the full thickness plus a minimum of 3/16 beyond the sheet or drum thickness to a maximum 1/2. Its very common to use four or five different tools when repairing watertube boilers.
