Summary
HSE alerts operators to carbon steel degradation through high temperature hydrogen attack. It distinguishes safer metallurgy for new or replacement equipment from cautious use of Nelson curves for existing plant. Recommendations address operating histories, temperature and hydrogen partial pressure limits, validated complementary non-destructive testing, examination intervals and specialist inspector competence.
