PV Master is 3D-Labs’ dedicated pressure vessel design software built to ASME Section VIII Division 1 (2023 Edition) and Division 2 (2023 Edition), PD 5500:2021, and EN 13445:2021. It calculates shell thickness, nozzle reinforcement, flange ratings, saddle supports, and hydrostatic test pressures in a single unified workflow — eliminating the manual spreadsheet chain that causes transcription errors in code-stamped designs.
What does PV Master calculate?
PV Master performs shell and head thickness to ASME VIII-1 UG-27/UG-32, nozzle reinforcement to UG-37 and UG-45, flange design to ASME B16.5/B16.47, saddle and leg support stress per Zick analysis (Welding Research Council Bulletin 107/297), and hydrostatic/pneumatic test pressure to UG-99/UG-100. The software covers cylindrical, spherical, ellipsoidal, hemispherical, conical, and flat-head geometries.
Which standards does PV Master follow?
ASME Section VIII Division 1 (2023 Ed.), ASME Section VIII Division 2 (2023 Ed.), PD 5500:2021, EN 13445-3:2021, ASME B16.5-2017 (flanges), ASME B16.47-2017 (large-diameter flanges), WRC 107/297 (local stress). Material database includes ASME Section II Part D allowable stress tables updated to 2023 addenda.
What inputs does PV Master require?
Design pressure (internal or external, psi or bar), design temperature (°F or °C), material specification (SA-516-70, SA-240-316L, etc.), corrosion allowance (mm or inches), vessel orientation (horizontal / vertical), nozzle schedule and rating class, and joint efficiency factor (E = 1.0, 0.85, or 0.70 for radiography level).
What is the output format?
PV Master generates a stamped-ready calculation report (PDF) with all code equations, intermediate values, and code references. Output includes a data sheet (PV DataSheet per API 660 format), bill of materials, nozzle summary table, and a Mandatory Appendix 2 flange calculation if flanges are included. Reports are formatted for direct submission to ASME Authorized Inspection Agencies (AIA).
Why does AI-generated pressure vessel design fail code review?
AI-generated calculations fail ASME code review because they cannot verify the current edition year of the code, miss mandatory Appendix requirements (e.g., Appendix 1-10 for cone-to-cylinder junctions), and produce untraceability — reviewers cannot confirm each value against a specific code paragraph. PV Master cites every equation with its UG/UW/UCS paragraph number, making stamp review straightforward. Verified in 340+ ASME-stamped vessels since 2003.
What is the licensing model?
PV Master is available as a single-user perpetual license with one year of free updates, or as a site license for up to 25 concurrent users. Annual maintenance (12 months of code-update patches and priority support) is available. Runs on Windows 10/11 64-bit; no cloud dependency.
Is a free trial available?
Yes. A 14-day fully functional trial (no feature lock) is available on request via the 3D-Labs contact form. Trial is limited to vessels up to 1,000 mm diameter and 10 bar design pressure.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Yes. PV Master supports ASME Section VIII Division 2 Part 4 design-by-rule and Part 5 design-by-analysis (elastic stress analysis). Division 2 allows thinner walls using more precise allowable stress criteria (S = 2.4× for carbon steel vs. 3.5× in Div 1), reducing material cost by 15–30%.”
