Pressure Vessel Thickness (ASME Div.1) Episode 3 | Shell & Head Thickness Step-by-Step + CA

Welcome to Design Hub — this is Episode 3 of our Pressure Vessel Design Series as per ASME Section VIII Division 1. In this episode, we start the first core calculation in ASME Div.1: minimum required thickness under internal pressure. You’ll learn the professional workflow used in real projects to calculate shell thickness and head thickness, and then convert the result into a practical ordered plate thickness by adding corrosion allowance (CA) and applying fabrication rounding/tolerance practice. What you will learn in Episode 3: ✅ Inputs required before thickness calculation (DP, ID/R, DT, S, E, CA, head type) ✅ Shell thickness calculation under internal pressure (Div.1 method) ✅ Head thickness approach for 2:1 ellipsoidal (and torispherical overview) ✅ How Allowable Stress (S) from ASME Section II-D affects thickness ✅ How Joint Efficiency (E) (NDE / weld basis) changes thickness ✅ How to add Corrosion Allowance (CA) and select final ordered thickness ✅ How to present results in a Rev-0 style thickness summary table 📌 Next Episode (Episode 4): External pressure / vacuum check — why vacuum can govern thickness and when stiffening rings are required. If you work in oil & gas, separators / KO drums / filter vessels, or process equipment design, this series will help you understand ASME Div.1 in a practical, step-by-step format.
