Finding the Root Cause of Boiler Tube Failures

Symptoms: Localized wall loss on the inside diameter (ID) surface of the tube, resulting in increased stress and strain in the tube wall.. Causes: Caustic attack occurs when there is excessive deposition on ID tube surfaces.This leads to diminished cooling water flow in contact with the tube, which in turn causes local under-deposit boiling and concentration of boiler water chemicals.
