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 …
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 …
LET’S SAY (just occasionally maybe) that some reports are not as good as they could be. You’ve paid for them (or someone has) and they just don’t give value for money. We’ve designed the Wilkinson Coutts REPORTING MASTERCLASS WORKSHOP to make your reports valuable. Join our 2-day public workshop. We take a maximum of 10 delegates so we can give everyone …
Sometimes, A Little Change Is A Good Thing Fitness For Service Training – API 579/ASME FFS-1 – must be up there as one of the most comprehensive and helpful resources out there in the world of technical codes and standards. First published in January 2000 it provides the refining and petrochemical industry with various methods for the reliable …
Fitness For Service – Local Metal Loss Level 1 Assessment. Part 3 of our 3 part series takes a look at the assessment of local metal loss. As we discussed in Part 1, there is strictly no definition of what constitutes local metal loss compared to general, so the accepted rule of thumb is to start with a Part 4 …
Fitness For Service General Metal Loss One of the most common damage classes (modes) found in static mechanical plant is metal loss. It can be caused by a number of damage mechanisms such as; -Atmospheric corrosion -Erosion -Sulphidation -Corrosion Under Insulation (CUI) -Microbiological Induced Corrosion (MIC) -Under Deposit Corrosion(UDC) -CO2 corrosion There are many more, and these can …
The phone rings, my taxi is here. I kiss my family goodbye. My 4 year old runs off to play with something as my impending absence is instantly forgotten about. Unicorns are obviously much more interesting. My wife with a 7-month-old in her arms wishes me a safe journey before closing the door and rushing off to see what that …
What are the PSSRs and what do they cover? The Pressure Systems Safety Regulations 2000 (PSSR) cover the safe design and use of pressure systems with the aim to prevent serious injury from the hazard of stored energy (pressure) as a result of the failure of a pressure system or one of its component parts. The regulations are …
This article ‘Back to basics – Material Properties’ covers the essential properties when considering asset integrity. Material science in itself is a huge subject, with endless reference books and academic courses that cover the subject. Only a high-level understanding will be provided in this article. Stakeholders should be concerned with ensuring pressure equipment is safe to operate and the …
Pressure Relief Valves – Pressure equipment requires protection from over pressurisation. A common way to protect vessels is the installation of a pressure relief valve. A pressure relief device is actuated by inlet static pressure and designed to open during an emergency or abnormal conditions to prevent a rise of internal fluid pressure above the specified design value. This device …
