In the field of industrial facility engineering, atmospheric storage tanks constitute one of the most critical and, simultaneously, most regulated assets. Two of the most widely used international standards for vertical welded steel tanks are API 650 (American Petroleum Institute) and EEMUA 159 (Engineering Equipment and Materials Users Association). Although both share a common objective—ensuring […]

The maintenance and design of storage tanks is not a secondary task; it is a fundamental engineering discipline in industrial plants that requires in-depth knowledge of materials mechanics, corrosion, and the rigorous application of international codes. Atmospheric and low-pressure tanks represent the most vulnerable link in the storage chain for hydrocarbons and chemical products. Their […]

API 653 is a standard published by the American Petroleum Institute (API) that governs the inspection, repair, alteration, and reconstruction of aboveground storage tanks (ASTs) used in the petroleum and chemical industries. This standard is crucial for ensuring the continued safe and reliable operation of tanks throughout their service life. Notably, API 653 is fundamentally […]

The API 653 standard was developed to guide during the inspection, repair, alteration and dismantling works of storage tanks designed and manufactured under API 650 or API 12C. Contents are divided into the following sections: Scope References Definitions Suitability for Service Brittle Fracture Considerations Inspection Materials Design Considerations for Reconstructed Tanks. Tank repair and Alteration […]
