³» ¿ë	*PES21 ENGINEERING WEBPROGRAM EVALUATION INFORMATION * PRESSURE VESSEL DESIGN The Vessel Design software is a comprehensive, industry leading application that has the ability to automatically design pressure vessels. It's goal is to provide you with a mechanical calculation easly in a short amount of time with no waste. Here are just a few features available in the program: Automatic break up of long shell sections into shorter cans for design calculations. Automatic selection of all thickness for each vessel component including, stiffeners, supports /etc. Selection of vacuum stiffener location and sizes. Selection of material properties from a large database. Sizing of baseplate and chair requirements. Sizing of legs and required attachment to shell. Sizing of lugs and required attachment to shell. Sizing of saddle including contact angle, web, ribs, base, etc... Selection of nozzle neck (pipe or plate). Selection of nozzle reinforcing pad. Selection of vessel Maximum Working Pressure(s). Large or small fractionation towers. Reactors and other heavy wall/high temperature vessels. Lug or leg type supported vessels. Large or small horizontal vessel on two saddles. * APPLIED ASME CODE WITH LATEST CODE EDITION ASME Section 8 Division 1 ASME Section 8 Division 2 API650 Appendix for Shop Built Vessels BS5500 Pressure Vessel Code Uniform Building Codes for both wind and seismic loading. ANSI A58.1 1982 Code for static wind, seismic and dynamic wind loadings. * COMPONENTS DESIGN 2-1 Elliptical Head (ASME type or non-standard w/ "K" factor) Flanged and Dished heads(User may input dish/knuckle radius) Div 2 requires a minimum straight flange length) Hemispherical heads. Conical Head (with or without knuckles) Flat Head (user may control the "c" factor) FLANGED w/ BLIND Flange Bottom Skirts supported at grade or in a structure. Intermediate Skirts- supporting one vessel on top of another vessel Skirt Support in middle of vessel (i.e. ballerina type skirts) All skirts may have one or more Materials All skirts may have one or more Diameters Baseplate/Chair arrangements- Many to choose from Two saddle supports with user controls of all design parameters Vectorization of vertical loads w/ lateral or axial loads Wind effects Seismic effects Friction effects Leg Attachment to shell Reinforcing Pads Girder design for large thin shells. * MATERIAL PROPERTIES Stress table as a function of temperature. Allowable stresses are selected for Internal and external design temperature Material density Vacuum chart for longitudinal stress and External pressure Yield stress Modulus of elasticity
