Who's Behind FlowEngineer
SZ
FlowEngineer Editorial Team
Mechanical Engineer · Founder, FlowEngineer · since 2018
FlowEngineer Editorial Team is a mechanical engineer with over a decade of experience in the design of industrial valves and pumps. He has worked across upstream oil and gas, petrochemical, and power generation sectors, with hands-on involvement in pressure-containing component design to ASME B16.34, API 6A, API 600, and API 6D.
He started FlowEngineer in 2018 as an independent technical resource — covering valve engineering fundamentals, selection guides, and calculation tools — built for engineers, specifiers, and procurement teams who need a reliable reference outside vendor marketing materials.
What's On This Site
FlowEngineer is organized into four content sections:
- Knowledge Base — Concise technical references on valve types, materials, standards, and engineering terms (API / ASME / IEC / ISO sources cited).
- Calculators — Browser-based engineering calculators for wall thickness, bolt load, stem torque, plug strength, flow coefficient, and more. Every formula is audited against the original calculation book before publication.
- Articles — Industry news and field engineering notes from the oil & gas, power, and petrochemical sectors.
- Directory & Catalog — Supplier directory and product catalog for valve & pump procurement.
Editorial Standards & AI Disclosure
All articles and calculators on this site are written and technically audited by FlowEngineer Editorial Team. AI assistants (ChatGPT, Claude) are used for drafting and language polishing, but every technical figure, formula, standard reference, and engineering conclusion is verified against original standards (API, ASME, IEC, ISO) before publication.
For calculators, each tool's calculation logic is cross-checked against a real valve calculation book (e.g. 16Q347F300 ball valve, 4″X43F-150Lb plug valve) and any errors found in the source are documented and corrected in the implementation.
AI Use Disclosure: This website uses AI tools for content drafting and language polishing. All technical content (formulas, standards references, engineering conclusions) is independently verified by FlowEngineer Editorial Team before publication. No content is published without human technical review.
