Looking for a trusted PVElite alternative? PV Master is affordable pressure vessel design software from 3D-LABS that helps you get the job done faster, with a simple, reliable workflow.
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.
Is PV Master a Good PVElite Alternative?
PV Master is a powerful and affordable PVElite alternative for pressure vessel design, delivering ASME Section VIII Division 1 compliant calculations at a fraction of PVElite licensing cost, making it ideal pressure vessel design software for EPC teams and independent mechanical engineers.
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.
Who Should Use PV Master as a PVElite Alternative?
PV Master is built for pressure equipment engineers who need ASME Section VIII Division 1/2, PD 5500, or EN 13445 compliant shell, nozzle, and flange calculations without chaining together multiple spreadsheets. It suits fabrication shops preparing code-stamped design packages, engineering consultancies handling multi-code export projects, and plant engineering groups re-rating existing vessels for higher operating pressure, temperature, or corrosion allowance. PV Master pairs well with 3D-Labs’ other engineering software: PIPE Master for pipe stress analysis, STR Master for structural stress analysis, TANK Master for storage tank design, and DRAFTY for 2D/3D drafting. See the complete lineup on the 3D-Labs engineering software page.
Support
Each PV Master license includes email support for installation, code-edition updates, and questions about mapping ASME Division 2 Part 5 stress categories or PD 5500 design-by-formula clauses to a specific vessel geometry, and guidance on choosing between Division 1 and Division 2 for a given design margin and expected fabrication cost.
