مواصفة قياسية خليجية فعالة صناعة النفط والغاز الطبيعي - المواد المستخدمة في صناعة معدات ومنشآت انتاج النفط والغاز في البيئة المحتوية على كبريتيد الهيدروجين – الجزء الثاني : الفولاذ الكربوني ومنخفض الكربون المقاوم للتشقق وحديد الزهر المستخدم

English Title

Petroleum and natural gas industries — Materials for use in H2S-containing environments in oil and gas production — Part 2: Cracking-resistant carbon and low-alloy steels, and the use of cast irons

Category

قطاع النفط والغاز Oil and Gas Sector

Scope

This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations.

This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC).

This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC).

This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed.
