The American Petroleum Institute (API) is a renowned organization that develops and publishes standards for the oil and gas industry. One of its most widely adopted standards is API 610, which provides specifications for centrifugal pumps used in the industry. The 13th edition of API 610, published in 2021, is the latest revision of this standard. In this article, we will explore the key aspects of API 610 13th Edition and its significance in the oil and gas industry. For pumps over 100 kW (134 HP), a

| Standard | Application | Key Differences from API 610 13th | |----------|-------------|------------------------------------| | ISO 13709 | Identical | Same (harmonized) | | ANSI/HI 14.1-14.2 | Industrial / process | Lower reliability, lower cost, smaller safety margins | | ISO 5199 | General purpose | No requirement for centerline mounting, weaker nozzle loads | | NORSOK M-630 | Oil & gas (Norwegian) | Additional requirements for subsea & extreme cold | | Shell DEP | Refinery | Stricter vibration and material traceability | Note | |---|---|---|---| | S-1 | Carbon steel
