Description
This course contains the use of artificial intelligence.
Step into the world of high-stakes oilfield materials engineering with this complete, industry-aligned program on API 6A CRA (Corrosion Resistant Alloys). Built for engineers, inspectors, metallurgists, and technical professionals working with wellhead and Christmas tree equipment, this course bridges the gap between specification reading and real-world material decision-making in sour, sweet, and HPHT environments.
You will start from the foundations of API Specification 6A (21st Edition) and progress systematically through corrosion mechanisms, alloy metallurgy, material class selection (AA through HH), Product Specification Levels (PSL 1-4), and the latest NACE MR0175/ISO 15156 requirements for cracking-resistant materials. Dedicated modules dive deep into age-hardened nickel-based alloys including Alloy 718, 725, 925, 716, 935, and 945 - covering chemistry, heat treatment, delta phase control, and qualification testing.
What makes this course stand out is its emphasis on application. You will work through real failure investigations from the UK North Sea, Gulf of Mexico, and Middle East sour gas developments, plus structured material selection examples from Australian LNG projects. Expert tips on PREN calculation, NACE documentation, PSL cost-benefit analysis, and SSC troubleshooting prepare you to apply the standards confidently on the job.
By the end, you will be able to specify the correct material class, PSL, and CRA grade for any service condition, audit compliance documentation, and prevent costly failures in critical oilfield equipment.
ISO Xpert Academy is a specialist training provider focused on international standards, quality systems, and technical compliance for the energy, manufacturing, and engineering sectors. Our courses are designed by certified industry practitioners to deliver practical, audit-ready knowledge you can apply from day one.
