On April 2, 2010, the catastrophic failure of a heat exchanger at the Tesoro Anacortes Refinery in Washington led to a deadly explosion, killing seven workers. The root cause was identified as High-Temperature Hydrogen Attack (HTHA), a damage mechanism that degrades steel when exposed to hydrogen at high temperatures and pressures. Although the equipment was operating under conditions deemed safe …

Mastering Technical Report Writing for Pressure Equipment Inspection and Assessment – In the field of pressure equipment inspection and assessment, the ability to produce a clear, accurate, and thorough technical report is an invaluable skill. These reports play a crucial role in documenting compliance, conveying the condition of critical equipment, and providing recommendations for maintenance or repair. A well-crafted report …
Pitting corrosion poses a serious threat to the integrity of metallic structures, primarily due to its highly localised nature. Unlike uniform corrosion, which affects larger areas more predictably, pitting targets small, concentrated spots on a metal’s surface, leading to the formation of cavities or “pits” that can penetrate deeply into the material. Even when the overall mass loss is minimal, …
Developing a comprehensive inspection plan (WrittenScheme of Examination) for pressure vessels is not just usually a regulatory requirement—it is essential for ensuring the safety, reliability, and longevity of industrial equipment. For those in industries such as oil refining, chemical processing, and petrochemicals, the extreme operating conditions and hazardous materials involved make a well-structured inspection plan critical. This article explores the …
