How Section VIII is structured, what Division 1 covers and where its scope ends. Covers finding your way around the code quickly, which is most of the difficulty the first few times.
The pressure-retaining parts of a vessel and the job each one does. Covers head types and where each is used, and why nozzles and manholes are the parts that drive most of the design effort.
Supports for horizontal and vertical vessels, and the attachments welded to the shell. Covers how support arrangement feeds back into the shell stresses rather than sitting apart from them.
Wall thickness calculation for shells and heads under internal pressure, worked step by step. Covers how allowable stress, joint efficiency and corrosion allowance enter the same calculation.
The external pressure and vacuum case, and the buckling mode it produces. Covers the Section II Part D chart method and the stiffening rings used when a shell will not pass on thickness alone.
Setting design pressure and design temperature, and the combinations a vessel must be checked against. Covers MAWP, hydrostatic test pressure and the relationship between them.
Erection, operating and test weights, and the wind and seismic loads applied alongside them. Covers which combination governs and why it is rarely the obvious one.
Material selection against service, temperature and cost, using ASME Section II Part D. Covers reading allowable stress at design temperature and where an alloy earns its price.
Joint categories, weld types and the joint efficiency each produces. Covers how the extent of radiography chosen changes the efficiency and therefore the wall thickness.
Nozzle reinforcement by the area replacement method, worked through in full. Covers the limits of reinforcement, reinforcing pads and the self-reinforced case.
A pressure vessel rarely fails its calculation. It fails its review — a nozzle without enough reinforcement area, a joint efficiency taken on faith, an external pressure case nobody ran, a material allowable read at the wrong temperature.
ASME Section VIII Division 1 tells you what is acceptable. It does not tell you how to get there. The gap between reading a clause and producing a design that survives a vendor drawing review is where most engineers stall, and it is the gap this course is built to close.
In this course you will work the Division 1 design route in order — design conditions and load cases, material selection, joint efficiency, internal pressure, external pressure and buckling, and nozzle reinforcement — calculating each step rather than describing it.
WHAT YOU WILL LEARN TO DO
By the end of this course you will be able to:
· Calculate shell and head wall thickness to Division 1 for internal pressure
· Set design pressure, design temperature and the load combinations a vessel is checked against
· Select a material to Section II Part D and read allowable stress at design temperature
· Determine joint efficiency from joint category, weld type and the extent of radiography
· Check a vessel for external pressure and buckling using the Section II Part D charts
· Design nozzle reinforcement by area replacement and apply the limits of reinforcement correctly
· Size and position supports, saddles and lugs for operating and test conditions
· Apply MAWP, hydrostatic test pressure and corrosion allowance correctly through a design
· Review a vendor's vessel drawing and calculation set against the code
· Recognise the loadings Division 1 does not address and where the work moves to Division 2
HOW THE COURSE IS TAUGHT
· Two hours and forty-seven minutes of focused instruction — every calculation worked through rather than stated, so the numbers can be reproduced and defended
· Built in the order the design actually happens, from design conditions through to nozzle reinforcement
· A knowledge check after every lecture — ten quizzes in all — so gaps surface as you go
· Two full course examinations at the end
· Clear about where the code is prescriptive and where the decision is yours, which is the distinction that matters in a design review
· No software, licence or copy of the code is needed to follow along
· Every presentation is included as a downloadable PDF, so you keep the slides as a desk reference after the course
WHAT IS COVERED
· How Division 1 is organised, and finding your way around the code quickly
· Internal elements — shells, heads, nozzles and manholes
· External elements — supports, saddles, lugs and attachments
· Internal pressure design and wall thickness calculation
· External pressure, buckling and the collapse case engineers most often skip
· Design conditions — pressure, temperature and load combinations
· Design weights and load analysis, including wind, seismic and operating loads
· Material selection and ASME Section II allowable stresses
· Joint efficiency, joint categories and the effect of the radiography selected
· Nozzle design and reinforcement by area replacement
· Two full course examinations
WHO THIS IS FOR
· Mechanical and process engineers moving into pressure vessel design
· Design engineers in oil and gas, petrochemical or power generation
· Fabrication and quality engineers checking vessels for code compliance
· Project and package engineers reviewing vendor vessel drawings and calculations
· Inspection engineers who need the design basis behind what they are assessing
· Engineering students and graduates heading into pressure equipment design
ABOUT YOUR INSTRUCTOR
I am a Chartered Engineer (CEng MIMechE) with over fifteen years in oil and gas, energy and industrial infrastructure, across a range of projects and disciplines.
For more than five years I have also been teaching. Close to twenty thousand engineers have taken my courses, which hold an average rating of 4.26 across the catalogue.
I build these courses because I am genuinely interested in how engineering works and why it fails, and because most technical subjects are taught far worse than they need to be. My aim every time is to produce the course I would have wanted when I first met the subject — practical, honest about what actually matters, and free of the padding that wastes your time.
REQUIREMENTS
No prior pressure vessel design experience is required — the code route is built up from the start. Basic mechanical engineering knowledge helps, and comfort with basic algebra covers every calculation in the course. No software, licence or copy of the code is needed.
70 PRACTICE QUESTIONS
Every section ends with a quiz built around realistic scenarios, so you test your understanding as you go and reinforce what you have learned. Each answer comes with a short explanation.
