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

The EPC Difference

One firm.
Every discipline.

Most firms hand off between engineering, procurement, and construction. We don't.

01

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.

02

Stamp

Licensed Professional Engineers review and seal drawings and calculations across mechanical, piping, structural, and electrical disciplines — including PE-certified critical lift plans.

03

Build

Procurement, fabrication, certified heavy crane lifts, electrical installation, refractory crews, and construction management — self-performed inside operating plants.

Client Feedback

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.
