#420 - Mechanical Design and Maintenance of Pressure Vessels
Course Objective
This practical, applications-oriented course is divided into two sections: pressure vessel design and pressure vessel maintenance. Upon completion of this course, attendees will be able to evaluate the mechanical design of pressure vessels in accordance with the ASME Code Section VIII. They will also be able to develop a pressure vessel maintenance program based on API 510 and other industry practices, and then apply these requirements to typical pressure vessel maintenance situations.
Who Should Attend?
- Individuals who are responsible for evaluating the design of pressure vessels in accordance with the ASME Code Section VIII.
- Individuals who are responsible for evaluating the mechanical integrity of in-service pressure vessels in process plant applications. Managers who are responsible for implementing a pressure vessel maintenance program and desire an understanding of applicable evaluation procedures.
Course Description
Individuals who are responsible for designing, reviewing, and implementing pressure vessel maintenance programs should first have a good understanding of pressure vessel design. This course treats both the design and maintenance aspects of pressure vessels. It first provides the information necessary for individuals to be able to evaluate the design of pressure vessels in accordance with the ASME Code Section VIII, with the emphasis on Division 1. To do this, participants will learn the fundamental requirements specified in the ASME Code. It then provides the information necessary to develop a pressure vessel maintenance program and evaluate pressure vessel mechanical integrity in accordance with API 510 and other industry practices. The following topics are covered:
Section 1 – Pressure Vessel Design
- Basic Pressure Vessel Concepts
- Main Pressure Vessel Components
- Primary Pressure Vessel Process Functions
- Materials of Construction for Pressure Vessels
- Factors That Affect Material Selection
