Store description excerpt
Professional Pressure Relief Valve (PSV) Sizing Calculator based on API RP 520 PSV Sizing is a professional engineering application designed for process, mechanical, and safety engineers involved in the design and evaluation of pressure relief systems. The application performs pressure relief valve sizing calculations for liquid, vapor, steam, and two-phase flow in accordance with the procedures described in API Recommended Practice 520. The app helps determine the required relief valve orifice size and capacity, ensuring that protected equipment can safely relieve excess pressure without exceeding the allowable overpressure. It is suitable for use in refineries, petrochemical plants, chemical processing facilities, oil & gas installations, power plants, and other industrial applications. Key Features • Calculate pressure relief valve sizing for: Liquid flow Vapor/Gas flow Steam flow Two-phase flow • Determine: Required effective discharge area Standard API orifice designation Relief valve relieving capacity • Fluid Property Support Select common fluids from the built-in database Enter custom fluid properties for vapor calculations • Flexible Engineering Units Mass flow rate Volumetric flow rate Pressure Temperature Density And other commonly used engineering units • Professional Calculation Report Generate and export professional engineering calculation reports Ideal for documentation, design review, and project records • Fast, accurate, and user-friendly interface designed for field engineers, consultants, and engineering students. Applications Process Engineering Mechanical Engineering Safety Engineering Refinery & Petrochemical Facilities Chemical Plants Oil & Gas Industry EPC Engineering Companies Engineering Education Disclaimer This application is intended as an engineering calculation tool to assist qualified professionals. Users are responsible for verifying all results and ensuring compliance with applicable codes, standards, engineering practices, and project requirements. API RP 520 remains the governing reference for pressure relief valve sizing.
