[MW:23191] Corrosion Allowance for equipment

By Materials & Welding

Dear experts

 

Good day!!

 

In all corrosion prediction models for process units in oil and gas the prediction model calculate the corrosion rate for piping system and whereas the process condition in equipment such as the vessels, towers and exchangers is totally different with piping system the evaluation model is not applicable to predict the corrosion rate and calculate the corrosion allowance. So I want to know this phrase is correct or not;

"The corrosion allowance for equipment is at least equal to the worst corrosion allowance of pipes which connected to equipment".

If yes is there any specific code to verify the above phrase?


Thanks

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
