Flange Management

Flange Management is an independent engineering firm dedicated to safeguarding the integrity of your flange joints through rigorous, standards-compliant calculations and clear, defensible documentation.

Every analysis we deliver is fully traceable and audit-ready, providing proof that each connection meets—often exceeds—applicable codes. Whether you need a single verification or a plant-wide assessment, our experts and tooling scale to your exact requirements. Partnering with us gives you an impartial seal of confidence in the reliability and safety of your operations.

Our calculation platform delivers fast, transparent, and repeatable results—so you can make the right decision, first time.

What we do

  • Design & verification of flange joints across maintenance, commissioning, turnarounds, and day-to-day operation.

  • Standards-based calculations translating owner requirements into clear, actionable parameters for assembly, tightening, and inspection.

  • Independent engineering review that withstands client audits, regulator scrutiny, and internal QA/QC processes.

  • Plant-wide programs to baseline and improve joint integrity across units, assets, or entire sites.

Why Flange Management

  • Leak-tight performance: engineered calculations that target durability and long-term integrity.

  • Faster projects: reduce critical-path uncertainty during shutdowns and startups.

  • Lower testing burden: right-sized verification that optimizes pressure/integrity testing scope.

  • Resource efficiency: clear inputs, automated traceability, less rework.

  • Operational productivity: consistent torque bases, better gasket/bearing life, fewer unplanned interventions.

  • Financial impact: fewer leaks, less rework, higher uptime—better profitability.

Standards & compliance

We calculate, verify, and document to the codes your assets demand, including: EN 1591-1, ASME Section VIII (incl. Appendix 2), ASME PCC-1 (guidance for assembly), EN/DIN flange standards (e.g., EN 1092 / DIN), and client-specific specifications. Our deliverables make compliance explicit, traceable, and defensible.

How we work

  1. Define scope — line list, joint IDs, service conditions, and acceptance criteria.
  2. Compute & review — standards-compliant calculations with clear assumptions.
  3. Report & trace — audit-ready documentation, unique references, revision control.
  4. Improve & sustain — close gaps, standardize procedures, and build a repeatable integrity program.
