Hi Hdamyan
In our line of work we generally encounter pitting corrosion in heat affected weld zones (inside scrubber absorbers)rather than general corrosion.
Depending on the environment inside the scrubber and the alloy used, it can be very severe (but can be prevented).
Normally in line...
Hi Luciano
I think that even if you do find some "standard" data it's probably going to be wildly inaccurate anyway because every project is different.
Are there no tests that you can do to collate your own data for your project? I think that would probably be a more effective start than...
Hi All
I have a very old drawing of a storage tank which specifies a grade of carbon steel. I can't seem to find any info on it (BTW I'm no materials engineer). Could somebody point me in he direction of a datasheet or something for: SM A 37 B
Thanks very much.

As srider6 says, carbon steel should be fine at room temperature with minimal corrosion. The acid will pickup some iron contamination from the corrosion that is occurring and this may or may not be a problem depending on what you're using the acid for. If iron contamination is an issue you have...
From an economical stand point I'd say that if your CP system is still meeting the protection criteria (-850mV instant off or 100mV shift according to NACE SP0169-2007) then there is no need to replace the ground bed. Usually the manufacturer will specify an expected life of the ground bed and...
Have you considered using carbon steel rather than ss with anodic protection applied? I don't know the figures but I believe it is a cheaper option and can provide an equivalent service life.
