The primary purpose of performing inspections on equipment at an industrial plant is to ensure that the equipment is currently operating safely and to determine whether it will continue to be safe until the next inspection interval. This process is crucial to prevent catastrophic failures, ensure mechanical integrity, and maintain plant operability. Inspection plans must […]

API RP 579-1 is a practical recommendation developed by the American Petroleum Institute (API) that provides a comprehensive methodology for Fitness for Service Evaluation. This guide provides a structured approach to evaluating the ability of equipment to continue operating safely, specifying under which conditions once some type of damage, deterioration or defect has been detected, […]

Let’s consider, for example, a fully pressurized pressure vessel with a load applied on the nozzle as shown in the picture. This load creates a bending stress (secondary stress) at the nozzle-to-head juncture. In the left-hand side of the nozzle, this load creates a tension strain value ε1 (see below), somewhat beyond the yield strain […]

In industry, ensuring the safety, durability, and efficiency of systems is crucial, and pressure testing plays a vital role in achieving this. They are essential for verifying the structural integrity and sealing capacity of piping systems and equipment under pressure. The process involves subjecting a component or system to a pressure greater than its normal […]

In various industries, the integrity and reliability of infrastructure are critical for safe and efficient operations. Over time, equipment and structures may experience degradation, corrosion, or mechanical damage that necessitate repair. The American Society of Mechanical Engineers (ASME) has developed the PCC-2 (Post Construction Committee) standard, which provides guidelines for non-metallic repairs. This essay explores […]

In the realm of industrial storage tanks, stability and safety are paramount. These structures, which often contain hazardous substances, require a robust foundation system to withstand external forces and prevent catastrophic failures. API 650, developed by the American Petroleum Institute (API), provides guidelines for the design, construction, and maintenance of welded steel tanks for various […]
