Discontinuation of Remote API Proctored Exams API has recently decided to discontinue the option for remotely proctored exams for their core certification programmes, effective …
Ensuring the Integrity of Low-Pressure Vessels: Lessons from the Yenkin-Majestic Incident In this short article, I dive into the catastrophic failure at the Yenkin-Majestic resin plant, where poor design, inadequate pressure testing, and a failure to adhere to crucial safety codes led to a tragic explosion. This incident highlights the critical importance of ensuring that even low-pressure vessels are designed …
A-Z of Pressure Equipment Integrity We’re often asked, “What kind of things do your courses cover?” Well, we couldn’t get that all down on here, but here is an A-Z snapshot of some common topics that are covered in our training courses. A – Anodic Protection Anodic protection is a technique used to prevent the corrosion of metal surfaces by …
Navigating Temporary Repairs: Risks and Compliance Essentials Post Construction Codes (PCCs) API 510/570/653 define these as temporary repairs but a feature of ASME PCC-2 is that it provides technical details and leaves the user to decide themselves. What is temporary? There’s no agreed definition of temporary. The nearest is from API codes as ‘to the next maintenance/replacement opportunity’. Temporary …
FITNESS FOR SERVICE ASSESSMENTS (FFSAs) R-R-R-R DECISIONS We see lots of FFSAs during our training and consultancy activities at WILKINSON COUTTS. With the best of intentions, things sometimes get more complicated than they need to be. Let’s simplify things…. There are only possible output decisions of a FFSA, as shown in table 1 below; Run (as-is) Re-rate Repair Replace …
What is Patina? Patina is a layer of corrosion that forms on the surface of metal objects, particularly those made of copper, brass, bronze, and other metal alloys. Patina is formed by a combination of chemical and physical processes, including oxidation, corrosion, and the accumulation of pollutants and other substances on the metal surface. Patina can have a variety of …
Chloride Stress Corrosion Cracking (SCC) is a type of corrosion that can occur in metal alloys, especially in those that are used in corrosive environments. It occurs when metal components are exposed to both tensile stress and chlorides, forming cracks in the material. The damage caused by Chloride SCC can be severe and can result in material failure, leading to …
When most hear the words Stress Corrosion Cracking (SCC), our minds immediately start thinking of Chloride induced SCC in stainless steels or Sulphide SCC. However, In March 2019, Step Change in Safety issued a Safety Alert about slightly less common phenomena of Methanol Stress Corrosion Cracking in Carbon Steels. The incident occurred on an outlet line from a …
HF Damage Mechanisms – the threat to your assets. The US Chemical Safety and Hazard Investigation Board have issued the final report on a significant fire and related explosions that occurred in June 2019 at the Philadelphia Energy Solutions (PES) Refinery in Philadelphia, Pennsylvania (CSB). The cause of the accident, which shut down a refinery that could produce …
Living with weld defects comes as a surprise to many. Construction codes (ASME, EN etc.) are based on years of experience and contain acceptance criteria for materials, design, fabrication, testing and certification. A construction code is not specifically to produce fitness-for-service. Surprised? Here are some examples of when a code-compliant vessel may not be fit-for-service. – The materials …
