Hydrogen Sulphide effects on low alloy steels up to 36Rc
Hydrogen Sulphide effects on low alloy steels up to 36Rc
(OP)
This subject was partially closed in thread330-25461: Hydrogen Sulphide effects on low alloy steels up to 36Rc, but it will be good to know how long HRC 30-36 (or grater than 22) will survive in lower concentration of H2S. For North Sea wells will be 350-1000ppm (0.00035%-0.001%). This will probably make some difference on material survival to 2% of H2S from cited in the other post. Some of my clients are required to use non H2S steel (due to strength) for short operation(up to 24hours) in low H2S wells.

1. How long is a piece of string?
2. How lucky does your client feel?
Your client will, ultimately, be duty bound to heed the requirements of ISO 15156-2 unless they can come up with a satisfactory case to justify otherwise. Thus, you and they may like to refer to Figure B.1 of the ISO document.
