Corrosion monitoring is typically used in the following situations: Where risks are high - high pressure, high temperature, flammable, explosive, toxic processes. Where process upsets can cause high corrosivity. Where changes in operating conditions can
BOILER TUBE GRADES CARBON STEEL SA178 Carbon steels show mild corrosion resistance and fair strength up to 1000F. However, their usage above 800F must take into account the susceptibility to graphitization. Graphitization has not been a significant problem in thicknesses encountered in boiler tubing. Use of heavy section pipe above 800F, however, is not recommended. […]

Corrosion failures due to condensing flue gases containing H 2 O, SO 3 , NO x and HCl still occur more often than might be expected. The corrosion failures can be of several types: general corrosion, pitting attack and stress corrosion cracking (SCC). The chemistry of condensing gases is discussed, and some examples of corrosion in large‐scale installations are presented, including blast
12, and PEB‐5.3, the use of such austenitic alloys for boiler pressure parts that are water wetted in normal service is prohibited. (PG‐5.5 note 1). Austenitic alloys are susceptible to intergranular corrosion and stress corrosion cracking when used in boiler
