This Five-day program offers detailed insight and thorough understanding of the most common ASME codes, pertaining to design/ engineering and testing of the pressure vessels namely Section VIII Div. 1 and Section VIII Div. 2.
This course emphasizes understanding of ‘stated’ and ‘implied’ requirements (i.e. content and intent) of the codes. The participants would be explained in detail the mechanics of adopting and applying the code rules and design formulas for different Design conditions and Services.
ASME VIII Div. 1 is the most commonly adopted code which is simple and used friendly, where as, ASME VIII Div 2 is an alternative code which provides a better engineered vessel with detailed stresses calculations and more rigorous testing, and allows for savings in material costs (thinner parts may be used).
This course is designed to give the participants the confidence and practice for carrying out design and Fabrication and testing for new vessels and also carrying out strength calculations and assessment of integrity of existing vessels.
How to adopt code rules for different types of vessels and with various service conditions will be illustrated with numerous case studies.
Important code stipulation will be reviewed and discussed collectively with participants so as to address the difficulties and ambiguities they might have encountered during their working.
Each attendee must bring a Laptop computer with Microsoft operating system and Scientific Calculator.
Course Objective:
