Engineering
built to last.
Grey Engineering Enterprises is a full-service Professional Engineer–led EPC firm. We design, stamp, and build — pipe stress analysis, pressure vessel fabrication, heat exchangers, refractory and acid brick, steam and boiler systems, electrical & instrumentation/controls, civil & structural construction, and certified heavy crane lifts.
Heavy industrial engineering, end to end
From ASME code calculations to field crews laying fire brick — every discipline below is delivered and sealed under one roof by licensed Professional Engineers.
Climax Molybdenum
Steam Plant Renewal
A complete steam plant renewal inside an operating molybdenum facility — deaerator, steam drum, and boiler replacement; sulfur furnace refractory fire brick reline; new insulation systems; and resolution of historic boiler feed water pump vibration through flow studies and pipe stress analysis.
- Deaerator design, construction & replacement
- Steam drum & steam boiler replacement
- Sulfur furnace refractory fire brick reline
- Insulation & jacketing systems
- BFW pump vibration resolved — flow study + pipe stress
One firm.
Every discipline.
Most firms hand off between engineering, procurement, and construction. We don't.
Engineer
ASME code calculations, pipe stress analysis, electrical & I/C design, civil & structural engineering, 3D laser scanning, vessel and exchanger design — engineering owned by the people who will build it.
Stamp
Licensed Professional Engineers review and seal drawings and calculations across mechanical, piping, structural, and electrical disciplines — including PE-certified critical lift plans.
Build
Procurement, fabrication, certified heavy crane lifts, electrical installation, refractory crews, and construction management — self-performed inside operating plants.
What clients say
Grey Engineering came in, diagnosed the BFW pump vibration problem we'd been chasing for years, and fixed it through a combined flow study and pipe stress analysis. Professional, thorough, and they delivered exactly what they said they would.
Their refractory crew executed the sulfur furnace reline inside our compressed outage window without a single day's slip. The engineering behind the brick selection and dry-out schedule was exactly what we needed for that service environment.
Having one PE-led firm handle the vessel design, procurement, rigging, and all the piping tie-ins made the project dramatically simpler. No finger-pointing between contractors — one call, one team, one accountable engineer.
Engineering services in every state
Grey Engineering Enterprises serves industrial facilities in all 50 US states. Our PE-sealed engineering, fabrication, and construction services are available wherever your facility is located.
