Overview of Pressure Vessel Design - yogeshpatil - 10-06-2017 Overview of Pressure Vessel Design [attachment=17997] INTRODUCTION This Overview of Pressure Vessel Design course is part of the ASME International Career Development Series an educational tool to help engineers and managers succeed in today s business/engineering world. Each course in this series is a 4- hour (or half-day) self-contained professional development seminars. The course material consists of a participant manual and an instructor s guide. The participant manual is a self-contained text for students/participants, while the guide (this booklet) provides the instructional material designed to be presented by a local knowledgeable instructor with a minimum of preparation time. Instructor s Outline 1. Describe what a pressure vessel is. 2. Note that pressure vessels are used in a wide variety of industries. They can be designed for a wide variety of conditions and in a broad range of sizes. Instructor s Outline 1. Use this and following overheads to describe main pressure vessel components and shapes. 2. Shell is primary component that contains pressure. Curved shape. 3. Vessel always closed by heads. 4. Components typically welded together. 5. Vessel shell may be cylindrical, spherical, or conical. 6. Multiple diameters, thicknesses or materials are possible. 7. Saddle supports used for horizontal drums. Spreads load over shell. One support fixed, other slides. Instructor s Outline 1. Most heads are curved shape for strength, thinness, economy. 2. Semi-elliptical shape is most common head shape. 3. Small vertical drums typically supported by legs. Typically maximum 2:1 ratio of leg length to diameter. Number, size, and attachment details depend on loads. Instructor s Outline 1. Skirt supports typically used for tall vertical vessels: Cylindrical shell Typically supported from grade 2. General support design (not just for skirts) Design for weight, wind, earthquake. Pressure not a factor. Temperature also a consideration for material selection and thermal expansion. |
