It continues to be an invaluable resource for industry experts, ensuring that they stay ahead of the curve in an ever-evolving industrial landscape.
What Updates Contained in The Latest Version of API 571?
Here are the updates to API 571 in its latest edition:
1. Structure Changes
The organization of the document was modified by removing specific subcategories of damage mechanisms. Instead of having separate sections for things like mechanical and metallurgical failures, uniform or localized loss of thickness, high-temperature corrosion, and more, these were combined into a more streamlined format.
2. ANSI Approval
The document received approval from the American National Standards Institute (ANSI), indicating its adherence to recognized industry standards.
3. Damage Mechanism Changes
Three damage mechanisms were removed, with two of them being combined with other damage mechanisms. For example, “Steam blanketing” was combined with “Short-term Overheating-Stress Rupture,” and “Vibration-induced fatigue” was combined with “Mechanical Fatigue.” “Sulfate Stress Corrosion Cracking” was completely removed.
4. New Damage Mechanisms
Four new damage mechanisms were introduced, including “Brine Corrosion,” “Concentration Cell Corrosion,” “Hydrofluoric Acid Stress Corrosion of Nickel Alloys,” and “Oxygenated Water Corrosion (Non-boiler).”
5. Reordered Damage Mechanisms
In the 2020 edition, the order in which damage mechanisms are presented changed. In the 2011 edition, they were arranged by their relative importance, but in 2020, they are ordered alphabetically.
6. New Annex Added
A new annex (Annex A) was added, listing relevant standards and references that can be helpful when using API RP 571.
7. Introduction Paragraph
A new paragraph was added in the introduction section, emphasizing the role of identifying flaws as the first step in processes like Fitness for Service (FFS) and Risk-Based Inspection (RBI), as per API 579 and API 580.
8. Category Removal
The 2020 edition removed the previous categorization of damage mechanisms encountered in petrochemical equipment. This included five categories, like general and local metal loss, surface-connected cracking, subsurface cracking, microfissuring/microvoid formation, and metallurgical changes.
9. Metallurgical Terminology
The new edition uses more specific metallurgical terms, like mentioning the type of heat treatment (e.g., tempering, annealing) and the specific terms for metallic phases (e.g., alpha prime).
10. Statement Relocation
Several statements were moved from one part of the document to another, making it clearer and better representing their meaning.
11. US and SI Unit Changes
The equivalent values between the US and SI units were updated. In the 2011 edition, values were directly converted, but in 2020, they were adjusted to reflect the nearest integer value. Additionally, some mistakes in conversion values were corrected in the 2020 edition.
In summary, API 571 Latest Edition Update 2020 Publication is a vital resource for professionals in the oil, gas, and petrochemical industries, with the latest edition incorporating crucial updates to keep experts well-prepared and informed about the ever-evolving industrial landscape.
