Boiler feed water (BFW) corrosion is mostly the result of dissolved oxygen in the feed water, but is also related to the quality of the BFW and the quality of the treatment system.
Carbon dioxide (CO2) corrosion is most typically found in boiler condensate return systems that are not adequately treated with corrosion inhibitors (typically amines). Dissolved CO2 in condensate forms carbonic acid (H2CO3) which corrodes steels...
Cooling water (CW) corrosion may be the oldest form of corrosion in the petrochemical industry, yet the industry still struggles with it for two primary reasons.
Whether you decide for a Computed Radiography scanner with flexible imaging plates or a flat panel detector with the fastest imaging, or even combine the advantages of both technologies, DÜRR NDT's innovative systems offer high reliability and...
Most all flue gases produced by the combustion of fuels contain contaminants that can condense into acid droplets. The amount of contaminants will determine the concentration of the acid droplets.
MIC is caused by biological growth, i.e. organic slime (typically bacteria, algae, and fungi) in water under low flow or stagnant conditions. The industry experiences it in cooling water systems, piping, vessels and storage tank bottoms where the...
Current BSI and ASME codes for the construction of pressure vessels, boilers and piping specify that post-weld heat treatment is required if the thickness of the components being welded exceeds a specified value. This value depends on the type of...
The figures included in this article provide visual evidence of the effectiveness of the microwave NDE technique. Note the clarity of the internal defects and structures of interest apparent in all of the scans.
API is preparing to release the next edition of API 579 Fitness-For-Service (FFS) the first quarter of 2006. The many major enhancements that have been made to the next edition of API 579 will permit Owner-Users to evaluate new types of damage...
