I work in the refinery plant as an inspection engineer for material and corrosion.
I already knonw that there are some training courses of NACE like "Corrosion control in the Refinery Plant" or "Design for the Corrosion Control."
Are there any more training courses that you recommend for an...
I have a Delayed Coke Unit on sites. And there's a corrosion problem on elbow parts of coke cutting tool used for delayed coke drum. Of course, corrosion is not a big deal in this case.
But I tried to find the official technical guideline for cutting tool replacment. If the remaining thickness...
Normally speaking, dissolved oxygen could act as an accelerating parameter of corrosion.
I want to know more details.
Is there a quantitative relationship like if D.O. is 1 ppm, the corrosion rate will go up twice?
Or is there a minimum guideline of D.O. to avoid corrosion?
If anyone...
I'm looking for the NACE Standard for hydrotesting.
Is there a perfect drain means for preventing contamination of Cl? (Or any recommended means for drain?)
We had a GHT Reactor which is cladded with S.S. 321.
We should do a hydrostatic test with it.
Unfortunately it's cladded with S.S. 321...

In case of creep test, we conduct a test based on ASTM E139-06.
Anyway I should know tube's mechanical properties or chemical composition or something like that. And to know LMP value of tube, I should know the exact code of tube.
So then to know the characteristics of A200 tubes...
I want to conduct an life-evaluation test (including creep test, tension test) on ASTM A200 T9 Heater Tube.
But I found that ASTM A200 T9 code is expired.
I heard that ASTM A213 T9 code matches exactly with A200 T9 code.
Then where is the official comment about this matter?
I can't find it...
I want to conduct hydrostatic test for Austenitic S.S piping.
Test fluid is water without Cl ion (or minimize Cl ion).
But there's a one problem I worry about.
There's possibility that water could condensate whiel conducting test. And it's possible that Cl SCC could occur because the piping...
Thanks for everyone.
And I have one more question to zdas04.
I already read ASME B31.8 but it's about pressure vessels.
Not for pipings.
Isn't it?
Is there something I misunderstand?
I'm looking for the code about hydrostatic test pressure for piping. As I've found, the latest version is "ASME B31.3 PIPING GUIDE (2004)". And according to this code, the hydrostatic test pressure for piping is "1.5 x DESIGN PRESSURE x St/Sd".
But my team manager told me there's a new standard...
One thing is incorrect.
It's the graph about calculated sulfuric acid dew point vs. sulfur trioxide concentration in 10% water.
Not sulfur trioxide corrosion.
I'm looking for the data of the effect of SO3 (sulfur trioxide) on Sulfuric acdid corrosion.
I found a graph (from NACE Corrosion Engineer's Reference Book) about calculated sulfuric acid dew point in flue gas vs. sulfur trioxide corrosion in 10% water.
And this graph showed that dewpoint was...
I'm looking for the crack growth rate of Cl-SCC in Austenitic S.S (especially in 347 S.S).
I experienced Cl-SCC at a drain point(a dead leg) in HCR Heater Unit.
I read some papers about Cl-SCC, but all of them said that crack growth rate of Cl-SCC was depend on various conditions (pH, Cl...
