Dear sirs,
I kindly ask you about the following issue. I premise, I'm in an HIC environment, NACE MR0103 applicable.
My Client requires all piping (seamless pipes, forgings, castings) to be manufactured during steel making with the Vacuum Degassing Process (aimed to lower Hydrogen content to few ppm).
I find such a requirement to be applicable only to:
- plates (ASTM A516);
- welded pipes (ASTM A672);
because they are susceptible to HIC, but not to:
- seamless pipes (ASTM A106);
- flanges (ASTM A105);
- castings (ASTM A216 WCB).
Do you agree with my experience/understanding? Did it ever happen to you to buy, or manufacture, seamless pipes, forgings, castings with a Vacuum Degassing Process?
Thank you very much for your attention. Best regards,
ES
