Welcome to Design Hub — this is Episode 5 (Part A) of our Pressure Vessel Design Series as per ASME Section VIII Division 1.

In this video, we start the Nozzles & Openings chapter and build the most important EPC deliverable: the Nozzle Schedule. You’ll learn how to tag nozzles (N1, N2, N3…), classify nozzle services (inlet/outlet/vent/drain/PSV/instruments/manway), define orientation logically, and document everything in a GA-ready, fabrication-friendly format.

After this Part A, you will be able to create a professional nozzle schedule that aligns with process + piping + mechanical expectations.

What you will learn in Episode 5 (Part A):

What a nozzle really is (opening + neck + flange/end connection)

Why nozzles are high-impact (strength, fabrication, NDE, piping loads, maintenance)

Nozzle tagging rules (N1, N2… consistency with GA/datasheet)

Standard nozzle categories used in separators / KO drums / vessels

Nozzle schedule columns: Size, Class, Facing, Orientation, Projection, Remarks

Orientation basics: clock positions + distance from tangent line

Common beginner mistakes to avoid in nozzle planning
