Pressure Vessel Design

ASME Section VIII Division 1 · Shell · Heads · MAWP · Weight · Cost estimate

1Design Conditions

Design pressure P (gauge)

Design temperature (°C)

Corrosion allowance c (mm)

Typical: 1.5 mm general · 3 mm moderate · 6 mm severe

2Vessel Geometry

Orientation

Inside diameter ID (corroded)

Shell length — seam to seam (mm)

Head type

Standard for most pressure vessels. Best strength-to-weight.

Number of nozzles (info only)

Nozzle reinforcement check (UG-36/UG-37) is scoped out — verify in PVElite.

3Material & Weld

Material

CS pressure vessel plate — most common general service

Weld joint efficiency E

Typical for most process vessels.

Tag number (optional)

Indicative only. Allowable stresses are representative of ASME Section II Part D. Verify against the current code edition. Nozzle reinforcement, support saddles, and lifting lug loads are not included. Use certified software (PVElite, DesignCalcs) for final design and Code stamping.
