Thank you,SJones
I mean if hydrogen concentration in materials exceed some value,it will probably cause failure.Doesn't this method work?
At present,are there any methods to monitor materials hydrogen damage in high temperature hydrogen service?
I'm a junior corrosion engineer.Thanks in advance.
Thank you guys,now answer Goahead's questions:
the materials mainly are Cr-Mo steels such as 2.25Cr1Mo,3Cr1Mo in lower temperature sites and austenitic steels such as 321,347 in higher temperatures sites.Sometimes the based metal are Cr-Mo steels with austenitic overwelds.Temperature is about...
In hydrogen processing(cracking) unit,hydrogen permeation is not avoidable,how can I evaluate the risk of faliure on equipments or pipelines?
Is there an online-monitoring method now?Any clues will be appreciated.Thanks in advance.
