Steam Lines. Gas Mains.
Zero Compromises.
Certified pipefitters for hospitals, breweries, and industrial plants. When your system runs at 3,800 PSI, you don't guess at the weld.

Hydrostatic Test Rating
What 3,800 PSI actually means for your building.
Every completed system gets hydrostatic pressure-tested to 1.5× working pressure before a single valve opens. At 3,800 PSI capability, we test steam mains, glycol loops, and gas distribution lines that most contractors won't touch. When a competitor skips the pressure test — and many do — you inherit that liability at 2 AM during a January cold snap.
Emergency Response Window
Seventy-two hours from call to pressurized system.
A failed steam trap in a hospital isn't a maintenance ticket — it's a patient safety event. Our emergency dispatch covers boiler room failures, gas line ruptures, and heat exchanger leaks with a 72-hour full-system restoration guarantee. We keep Schedule 40 and Schedule 80 black iron in the truck because waiting on a parts order isn't an option when your HVAC is down.
Licensed Service Footprint
Eleven jurisdictions, one point of contact.
Municipal licensing isn't paperwork — it's the difference between a permit that passes and a stop-work order on inspection day. We hold active contractor licenses in 11 municipalities across the greater metro, which means your general contractor doesn't need to source a local sub for each jurisdiction. One crew, one insurance certificate, one call.
Engineered from the First Joint
New steam, gas, or process piping systems designed to ASME B31.1 and B31.3 standards. We work from P&ID drawings or develop them in-house for design-build contracts.
- Schedule 40 & 80 black iron, carbon steel, stainless
- Boiler room tie-ins and distribution mains
- Pressure relief and safety valve integration
Aging Systems Don't Have to Be Liabilities
We specialize in converting aging steam systems to high-pressure hot water, re-routing mains around structural changes, and upgrading distribution headers on operating plants.
- Steam-to-HPHW conversion
- Pipe rerouting during active operations
- Flange-to-weld upgrades for leak elimination
72-Hour Restoration. No Exceptions.
Gas line ruptures, steam main failures, and process loop breaks don't wait for business hours. Our emergency crew carries common Schedule 40 fittings, couplings, and valves on every truck.
- 24/7 dispatch — 4-hour on-site arrival target
- Temporary bypass installation while repairs complete
- Inspection-ready documentation same day
Steam Distribution Retrofit — 11 Weeks, 340 Joints
"Our 1974 steam distribution system had been patched by four different contractors over 20 years. IronThread came in, mapped every joint, and gave us a plain-English assessment of what was actually wrong. The retrofit took nine days. We haven't had an unplanned outage since."
