 · Web viewCorrosion weakens boiler metal by the thinning (removal) of the metal. Corrosion causes pitting and channeling of the metal, which results in the thinning of tubes, piping, and other boiler components. Corrosion is primarily caused by oxygen in the boiler water. Feedwater is treated to remove oxygen by heating and/or chemical treatment. Heating Cast-Iron BoilersCast-iron boilers typically have a few inherent problems. The inspector should always look for water leaks at the connecting joints of sectional boilers. The inspector should request the removal of the sheet metal casing any time there is evidence of leakage and the leakage cannot be Finding the Root Cause of Boiler Tube FailuresFailures 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 :Stainless Steel Double Boiler Pot for Melting Arrived missing parts and damaged. The long handle used to hold the boiler was missing and the small handle used to balance the boiler onto the lip of a pot was detached and mangled. The tiny metal plate used to attach the small handle was missing.

The only factor affecting shell-metal temperature is the bulk water temperature of the boiler. This is a function of the return water temperature and flowrate, and also burner firing rate. Obviously, low bulk water temperatures mean low shell-metal temperatures and vice versa.
