| Abstract [eng] |
This project is aimed to engineers who model and design vessels with applied internal or external pressure by ASME boiler and Pressure Vessel Code, section VIII, Division 1. The aim of the project is to design and verify safety of pressure vessel with half-pipe coil according mentioned standard. Every standard or code provides its own safety requirements. The main safety requirement for pressurised vessels is based on determination of vessels components minimal thicknesses. After thicknesses are set and vessel fabricated pressure test must be applied to pressurised components to ensure safety of pressure vessel. The main problem of research is that ASME code provides only recommendations what minimal thickness for vessel’s conical bottom should be used in case if pressurised half-pipe coil is welded on it. Every engineer can follow this rule and use recommended minimal thickness but in our case we bypass this rule and reduce minimal required thickness by determining actual materials yield strength, making Finite Element model and applying pressure test. These changes of vessel design are important because it reduces materials costs. Also, production time is reduced because thinner steel sheet is better wieldable and formable. Therefore the objectives of Master project were defined as follow: • “Jacketed” pressure vessel analysis; • Construction and design of vessel; • Design calculations; • Standard tensile test; • Pressure test of vessel. |
