Introduction to ASME Section VIII Division 1 Pressure Vessel Code

Course Code: N626
Instructors:  John Curry
Course Outline:  Download
Format and Duration
3 days


This three-day course will introduce participants to the ASME Section VIII, Division 1 Code for Unfired Pressure Vessels. It will provide an understanding of the background of the overall ASME Boiler and Pressure Vessel Code, it's organization, and applicability. Basic design rules and formulas, materials, welding, fabrication, testing, certification and documentation will be discussed. An extensive look into pressure vessel metallurgy, steel development and manufacturing will be done. Videos of steel making, clad manufacturing, and pressure vessels in fabrication will be presented. Sample design problems and fabrication issues will be addressed.


This course offered a great overview of Pressure Vessels from design to manufacturing and qualification.

Duration and Training Method

Three classroom days providing 2.4 CEU (Continuing Education Credits) or 24 PDH (Professional Development Hours)

Course Overview

Participants will learn to

1. Perform elementary design calculations using ASME Code formulas to determine wall thicknesses.
2. Apply Code rules to design, fabricate, and test pressure vessels.
3. Select suitable steels to deal with low temperature applications, sour services, and corrosive materials.
4. Understand the various welding processes used in today’s fabrication facilities.

John Curry received his Mechanical Engineering Training from the University of Michigan before transferring to the University of Texas at Austin to finish his undergraduate degree and proceed to a Masters of Business Administration degree. He attended two years of Metallurgy training at Rice University before founding Gulfex, Inc. a highly successful pressure vessel fabricator located in Houston, Texas. He founded and was CEO for 37 years. He is considered to be one of the world's foremost authorities on the ASME Boiler and Pressure Vessel Code, pressure vessel design and fabrication. John is an Internationally recognized instructor for pressure vessels and metallurgy. He teaches worldwide on pressure vessels, heat exchangers, piping and storage tanks. He regularly consults on pressure vessel design and fabrication and the rerating of existing vessels and exchangers.
