May 12, 2004 · We have seal welded tubes in the lower drum and in a steam drum on two aux boilers (100,000 lbs per hour) without a problem. On small boilers, you typically have to seal weld all of the tubes because the heat from welding will disturb adjacent tube rolls. A two pass seal weld works nicely using SMAW or GTAW.

Steam Generator versus Steam Boiler

Steam Generator Boiler versus the "classic" fire-tube Steam Boiler The principle in the fire-tube steam boilers, is that from the surface of a large volume of feed water, steam is evaporated. This boiling process is heated by the wall of the combustion chamber (the radiant part) and by the exhaust gasses passing through a bundle of so-called

Chapter 14 - Boiler System Failures | SUEZ

Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.
