PAULIN Research Group

What PAULIN Research Group does

PAULIN Research Group (PRG) is a Houston, Texas-based private engineering software company that has, since 1991, developed finite element analysis (FEA) software purpose-built for pressure vessel and piping design. Its flagship offering is the PVPT Design Suite, which combines four specialized products — NozzlePRO (advanced nozzle and multi-nozzle FEA with automated ASME Section VIII-2 compliance reporting), FlangePRO (flange design validation with axisymmetric and brick-element models and leak-risk assessment), FEPipe (multi-component, complicated-structure FEA for piping), and FEATools (supplementary analysis utilities) — with the standalone products PCLGold, Konnect, and Fabrication Manager. The company's core technical differentiator is automated regulatory compliance reporting tied to ASME, CSA, and WRC 107/537/297 standards, allowing engineers to produce code-compliant reports in minutes rather than days, alongside specialized multi-nozzle, fatigue, and flange analysis workflows that general-purpose FEA tools do not natively provide.

PRG monetizes through direct, consultation-led software sales distributed globally via its website, complemented by a professional services arm that includes same-day emergency FEA analysis, design validation, FEA training, and meshing solutions. Its customer base is a horizontal persona — pressure vessel and piping engineers across the Power, Petrochemical, Offshore, and Chemical industries — rather than named enterprise accounts. The firm is privately held, employs between 11 and 50 people, and is led by founder and President Anthony W. Paulin. It recently extended compliance to 2025 ASME and CSA codes (Build 2025.9.0.3066, October 2025) and partnered with Rezatec to bundle satellite InSAR ground-monitoring into its structural-integrity offering.

Core offering

PAULIN Research Group develops and sells finite element analysis (FEA) software for pressure vessel and piping engineers, packaged as the PVPT Design Suite that includes FlangePRO, NozzlePRO, FEPipe, and FEATools. The software automates ASME and CSA code compliance reporting so engineers can validate stress, flange, and nozzle designs in minutes. The company complements its software with professional services such as emergency FEA analysis, design validation, meshing solutions, and training.

Product overview

PAULIN Research Group offers a unified platform called the PVPT Design Suite for pressure vessel and piping finite element analysis (FEA), designed to help engineers validate designs and generate automated ASME code compliance reports. The suite includes specialized tools: FlangePRO for flange design analysis and leak risk assessment, NozzlePRO for advanced nozzle and multi-nozzle configuration analysis with ASME VIII-2 compliance, FEPipe for multi-component complicated-structure FEA, and FEATools as supplementary analysis utilities. Additional products include PCLGold and Konnect, which extend the platform's functionality. The company also provides professional services and meshing solutions to support implementation and emergency engineering analysis needs.

Recent moves5 records

Expansion highlights5 records

Direct peers

• Codeware: Codeware develops COMPRESS, a leading pressure vessel design and ASME code compliance tool. It is the closest direct competitor to PRG's NozzlePRO/FlangePRO, serving the same pressure-vessel engineer persona with overlapping ASME VIII workflows.
• Hexagon (Asset Lifecycle Intelligence): Hexagon owns PV Elite (pressure vessel design) and CAESAR II (pipe stress analysis), making it a direct competitor across both halves of PRG's product suite. It is also a broader incumbent with much larger R&D and distribution resources.
• Bentley Systems: Bentley's AutoPIPE is a widely used pipe stress and dynamic analysis tool, competing directly with FEPipe for piping engineers' ASME/B31.3 compliance workflows in the same power, petrochemical, and offshore segments PRG serves.

Broad incumbents

• ANSYS: ANSYS is the leading general-purpose FEA platform used in the same pressure vessel and piping projects PRG targets. It is a broad incumbent rather than a niche specialist, but its Mechanical and Fluent products often sit adjacent to (or compete with) PRG's NozzlePRO/FEPipe workflows.
• COMSOL: COMSOL provides a multiphysics FEA platform used in energy and process industries for pressure equipment and piping simulation. It is a broad incumbent that competes for the same engineering simulation budget, though without PRG's depth in ASME-specific compliance reporting.
• Dassault Systèmes (SIMULIA): Dassault's SIMULIA portfolio (including Abaqus) is used across pressure vessel and piping structural simulation in the energy and process industries. It is a broad incumbent with deeper multiphysics capabilities, often considered by the same engineering teams that buy PRG's tools.
• Siemens (Simcenter): Siemens' Simcenter includes 3D FEA and 1D system simulation tools used for pressure equipment and piping analysis. It is a broad incumbent whose industrial software portfolio overlaps with PRG's domain in the energy and process customer base.
• Autodesk: Autodesk's Fusion 360 Simulation and Inventor Nastran bring structural FEA into mainstream mechanical design tools. While not a specialist in ASME pressure-vessel compliance, Autodesk is increasingly relevant to the same engineering personas PRG targets.

Others

• Stress Engineering Services: Stress Engineering Services is an independent engineering consulting firm that performs FEA, pressure vessel, and piping integrity work for energy clients — overlapping with PRG's professional services arm and sharing the same customer base, though it does not sell competing commercial software.
• TÜV SÜD: TÜV SÜD is a global third-party testing, inspection, and certification body that consumes ASME code compliance reports generated by tools like PRG's. It is adjacent rather than competitive — PRG's software helps engineers produce the artifacts TÜV SÜD and similar bodies ultimately review.
