API 620
API 620 is a standard published by the American Petroleum Institute (API) that provides design and construction requirements for large, welded, low-pressure storage tanks used in the petroleum and chemical industries. It specifically covers tanks with internal pressures up to 15 psig (pounds per square inch gauge) and is commonly applied to vessels storing liquids such as crude oil, refined products, and chemicals. The standard ensures safety, reliability, and structural integrity by specifying materials, fabrication methods, inspection procedures, and testing protocols.
Developers should learn about API 620 when working on industrial software projects involving tank management, process control, or safety systems in the oil, gas, or chemical sectors, as it defines critical engineering parameters for compliance and risk mitigation. It is essential for designing or integrating software that monitors tank operations, calculates capacities, or ensures regulatory adherence in hazardous environments. Use cases include developing SCADA systems, inventory tracking applications, or maintenance scheduling tools for storage facilities.
