chloride | SPE

Corrosion under insulation influenced by chloride stress corrosion cracking (CUI-CLSCC); commonly occurs in insulated ageing austenitic stainless steel process equipment 1. Chloride in rock wool insulation can be penetrated by water ingress 2-5. As chloride concentration increases from liquid evaporation, it is sufficient to promote the phenomenon.

MARINE ENGINEERING KNOWLEDGE BY RAJAN -

– Regularly test the boiler water to determine the dissolved solids and salts. – Chemical dosing should be done as per the test result to keep the boiler scale free. Significance of regular partial blow down: 1. As the temperature rises the chloride comes out of solution that raises the boiler chloride level.
