PCLGold Leads Pipe Stress Evaluation with ASME Code Changes with Shell FEA in Latest Software Release

FEA-based Stress Output of a Piping Model in PCLGold

PCLGold now includes 2024 ASME B31.3 and B31.1 updates, reinforcing code compliance and FEA-based pipe stress analysis with shell models.

PCLGold automates tee intersection modeling, I-factors, i-factors, and k-factor FEA calcs, plus B31.3 fatigue checks—no manual model rebuilding & it captures worst-case range across all load sets”

HOUSTON, TX, UNITED STATES, June 19, 2025 /EINPresswire.com/ -- Paulin Research Group’s 2025.4.0.2787 release incorporates the 2024 ASME B31.1 and B31.3 code updates, augmenting its code coverage for use with its advanced finite element analysis (FEA) capabilities for piping system design and analysis. In PCLGold, these features support continued improvements in localized pipe stress analysis by utilizing shell models in addition to standard beam models where more insight is required.

PCLGold integrates directly with existing beam-based piping designs, applying FEA at intersections, nozzles, and other areas of geometric or mechanical complexity. This targeted approach supports more informed decisions during design, analysis, and verification, especially in systems where the typical B31 assumptions may not be valid.

The software helps reveal localized stress behavior in scenarios such as:

- Friction reversal at supports during thermal expansion and shutdown
- Axial and torsional effects on branch connections
- Load shifts in overhangs and risers due to condensate or sag
- Structural response changes caused by pressure or thermal stiffening

The inclusion of 2024 ASME B31.1 and B31.3 updates ensures current code alignment while maintaining PCLGold’s broader objective: to improve stress prediction fidelity in critical piping systems.

PCLGold’s analysis framework is supported by real-world validation, including fatigue, burst, and acoustic testing performed by Paulin Research Group. This foundation helps engineers assess conditions that influence fatigue life, equipment loading, and system reliability.
