PVelite – software for the overall design of pressure vessels: a) Operational features: PVelite makes use of the familiar Windows interface, featuring a quick and easy installation procedure as well as user-friendly dialog boxes. Additionally, its customization options allow users to organize their visual information according to their own work needs. It is simple to create container models using PVelite. By clicking on the components of the device, users can assemble various complete device models. Users can add detailed auxiliary components to the device elements, such as pipes, reinforcement rings, ladder platforms, supports (saddles, ears, legs), and so on. The model shows 3D and 2D regions that depict the detailed connection patterns and orientations between various components. Users can directly click on the component to obtain input information and make entries or modifications. Other features of PVelite include a toolbar and a design information assistance pre-computation status bar. Users can move the toolbar around on the screen to achieve the most suitable window layout. The design information assistance pre-computation status bar displays in real time the minimum inner and outer pressure thicknesses, vertical height, MAWP&MAPNC, etc., for the specified components, ensuring that users are always aware of the impact of changes in various design parameters on the calculation results. b) Standard specifications and software applications: The software includes the following standard specifications: ◇ASME BPV Code Section VIII, Division 1 & 2 Edition 2010 ◇British Standard PD 5500 Edition ◇European Standard: EN 13445-3: 2009(E) Issue 1 (2009-07) ◇TEMA Standards, Eighth Edition, 1999 ◇API-579 (Fitness for Service) as well as other commonly used international standards for load design ◇ASCE 7 – Minimum Design Loads for Buildings & Other Structures ◇Uniform Building Code ◇British Code 6399-97 ◇Indian standard (for wind and seismic loads) ◇ASME/ANSI B 16.5 – Pipe Flanges and Flanged Fittings ◇IS-875 ◇ASCE-98/02/05/IBC-03 ◇Me*co 1993 ◇As/Nz 1170:2002 ◇Euro Code ◇Brazilian standard NBR 6123 ◇Chinese standard GB 50009 ◇IBC 2006 ◇Canada’s National Building Code NBC-2005 ◇EN-2005 ◇International Building Code IBC 2009 ◇PDVSA ◇Chilean standard NCh2369 ◇Costa Rican standard 2002 ◇Chinese standard GB 50011. Users can design new equipment and conduct life assessments on existing equipment. The software can quickly determine the wall thickness of equipment and the dimensions of its components under various combined loading conditions, including internal and external pressures, weight, user loads, wind, and **. In the design of tall towers, the action of various static and dynamic loads often causes the structure to bend, resulting in tensile and compressive stresses at different sections; compression also induces tensile and compressive stresses in the axial direction. Pvelite will automatically combine these stresses and adjust the wall thickness of each element to create a new container that meets the strength requirements for tension and compression. PVelite users can also use this software to re-evaluate existing equipment in order to determine the remaining strength of those in service. c) Scope of analysis: The PVelite software covers almost all the contents of the ASME VIII-1&2, ASME II, PD5500, and EN-13445 standards (excluding the finite element analysis design aspects). Vertical vessels: kettles, tall towers. Horizontal tank heat exchangers (heat exchangers in various forms per TEMA/ASME/PD5500: fixed tube sheet, U-tube, floating head type; the calculations include those for the tube sheet, tube bundle, floating head, gussets of the heat exchanger, as well as the strength assessment of the connections between these components). ) d) Rich database – The software comes equipped with the following databases: ◇Complete material data that complies with ASME VIII-1&2, PD5500, and EN-13445 standards. ◇AISC, Korean/Japanese, German, UK, Australian, South African, Indian steel structure databases. ◇ ANSI flange dimension database – Flange database. ◇ ANSI pipe schedule database – Pipe database. ◇ Default bearing dimension database – Footing base database. ◇ Forged Vessel Connection catalog – Forged pipe connection database. PVelite boasts a variety of databases; it contains performance data for over 3,600 materials, including allowable stresses and yield strengths at various temperatures, external pressure curves, UCS-66MDMT evaluation curves, elastic modulus & linear expansion coefficient curves, as well as information on material types. The performance data for these materials is presented in the same format as that in ASME specifications, and it also features alphabetical sorting. The material groups include the following: carbon steel, titanium, stainless steel, zirconium, copper, nickel, aluminum, and the pipes listed in B31.3. By clicking on a material button, it is possible to view the allowable stresses at corresponding temperatures as well as other relevant data for that material. PVelite provides a material library editor that allows other specified materials or newly added materials to be included in the material library. It provides advanced and flexible analysis and calculation tools for your work. Data can be imported directly into Microsoft Word quickly and easily, or it can be sent straight to a printer for printing or converted into a PDF file.
