Welcome to Design Hub — this is Episode 2 of our Pressure Vessel Design Series as per ASME Section VIII Division 1.

In this episode, we build the Design Basis and the Mechanical Datasheet — the most important step before any thickness calculation. If you freeze the correct design inputs here, your shell thickness, head thickness, nozzle reinforcement, testing, and documentation all become smooth and review-ready.

What you will learn in Episode 2:

How to prepare a Div.1 Design Basis (code, service, assumptions, design philosophy)
How to create a Pressure Vessel Datasheet used in real projects
How to select:

Design Pressure (DP) (normal, upset, PSV/relief alignment)

Design Temperature (DT) (max metal temperature → affects allowable stress)

MDMT (minimum metal temperature → brittle fracture / impact test considerations)

Corrosion Allowance (CA) (service & design life basis)
Why you must define vacuum / external pressure case early (to avoid redesign later)
Where Allowable Stress (S) and Joint Efficiency (E) fit into the design basis

Next Episode (Episode 3): We start the first calculation — shell thickness and head thickness under internal pressure, step-by-step.

If you work in oil & gas, separators/KO drums, well testing skids, or process equipment, this series will help you understand ASME Div.1 in a practical and structured way.
