Piping stress analysis and mechanical design for nuclear, power generation, and industrial facilities. Led by Ali Khan — five years analyzing Class 1 and Class 2 piping systems to ASME code.
Piping systems carry real consequences when they fail — leaks, downtime, and in nuclear and power generation settings, safety incidents. AKHAN Mechanical Consulting Inc. exists to make sure that never happens on a line we've analyzed. We combine piping stress analysis, nuclear and power plant engineering, and mechanical design under one roof, backed by ASME code, CAESAR II, PipeStress, and SolidWorks — so every system we touch is verified, documented, and built to hold.
Piping design isn't guesswork — it's a defined sequence, the same one used on nuclear-class systems where there's no margin for error. Here's what happens between a P&ID and a stamped, code-compliant drawing set.
We start with the P&IDs, layout drawings, and applicable code — ASME B31.1 for power piping, ASME BPVC Section III for nuclear-class systems — to establish the design basis before a single calculation begins.
The system is modelled in CAESAR II or PipeStress, capturing every support, restraint, and equipment nozzle so the model reflects how the line actually behaves in service — not just how it looks on paper.
Sustained weight, thermal expansion, wind, occasional, and seismic loading — including Design Basis Earthquake and Review Level Earthquake cases — are built into the model, matching the same load combinations required on nuclear systems.
Results are checked against code-allowable stress limits, nozzle load criteria, and flexibility requirements. Pipe supports and bolting are verified separately under ASME Section III Subsection NF using classical and finite element methods.
Where a line doesn't pass on the first run, supports are relocated, resized, or reconfigured and the model re-run — iterating until the system clears every code requirement without over-building the supports.
Isometrics and support drawings are produced or updated to reflect the final design, and the calculation package is compiled for Engineering Change Control, TSSA registration, or client submission.
Four stages, each signed off before the next begins.
Site walkthrough, constraints review, and a hand-sketched concept with rough load calculations.
Detailed drawings, simulation, and materials selection. Every dimension is checked against code.
Prototype or bench testing where warranted, plus a full stamped drawing set for construction or fabrication.
On-site startup, balancing, and as-built documentation handed over with the final report.
Led by Ali Khan, mechanical engineering graduate of the University of Toronto. Five years across nuclear, power generation, and industrial piping — including multiple nuclear and Class 6 piping projects carried successfully from initial design through final as-built documentation.
Every completed project follows the same path: reviewing the existing piping and instrumentation diagrams, building the stress model, running the full set of sustained, thermal, wind, and seismic load cases, verifying supports and bolting, then producing or updating the isometric and support drawings needed for construction, Engineering Change Control, and TSSA registration — carried through on Class 1, Class 2, and Class 6 nuclear piping systems.
