We handle NFPA compliant wet pipe retrofits and emergency threaded black pipe leak repairs with mobile welding and on site fabrication trailers. At McMahan Industrial Services, we offer same day assessments, free on site consultations, and decades of licensed experience.

Corrosion, stripped threads, and pressure testing are routine for us. We show up, fix leaks, and document compliance — no drama. Local, reliable, and bluntly efficient.

Threaded Black Pipe Leak

Though a slow threaded black pipe leak might look harmless, it’ll chew through your uptime and budget before you know it.

We won't sugarcoat it: left alone, that threaded pipe ruins ceilings and schedules.

• Drip, drip, surprise shutdowns

• Corrosion eating threads, fittings failing

• Emergency crews chasing leaks at midnight

We offer pipe fitting, repair welding and mobile welding services. Our pipe welder employs portable welding services and welding for plumbing systems to stop leaks fast.

Additionally, our expertise in stainless steel pipe ensures that you have options that resist corrosion and extend the lifespan of your piping systems.

We care, we show up, we fix it right. Call before the drip becomes a crisis — you'll really thank us today.

NFPA-Compliant Wet-Pipe Retrofits

When an older sprinkler runs afoul of current NFPA requirements, we don’t tinker around the edges — we retrofit it to code, fast and with as little drama as possible.

We assess piping, prioritize safety, then execute with our mobile welding crews and experienced industrial welder with welding certification.

We do pipe fitting upgrades, welding for plumbing, welding for construction, and welding repair services — no nonsense, just reliable work.

We value uptime.

Typical retrofit tasks include:

• Replace corroded runs, rework joints

• Update hangers, seismic bracing

• Test systems, document compliance now

Call us; we’ll get it done right today.

Custom Pipe-Fitting Trailers

We bring the shop to you with our custom pipe‑fitting trailers — because running back to the shop mid‑job is for people who like wasting time.

We outfit each unit for pipe fitting and repair, mobile welding, welding for industrial equipment, welding for HVAC systems, and welding for pipelines.

We show up, cut, weld, and install — no drama, just work. McMahan mobile welding services keeps parts, tools, and skills on hand.

Imagine this:

• A heated trailer with full fabrication bay

• Organized parts and threaded pipe inventory

• Onsite welding and pressure testing, fast and tidy. Done.
