We're Iowa City's leading pipe fitting specialist for fire suppression systems, offering NFPA compliant sprinkler retrofits, rapid threaded black pipe leak repair, and same day on site threaded pipe replacement from our custom pipe fitting trailer.
At McMahan Industrial Services, we perform full pressure testing and sanitary audits, promising straightforward, no-drama service with fast turnaround and certified results. We're trustworthy, practical, and a little blunt—more specifics and scheduling options are just ahead.
Threaded Black Pipe Leak
Stop a threaded black pipe leak before it turns into a shutdown-level mess. We respond fast, diagnose threaded joints, and stop leaks with practical pipe fitting fixes and welding for plumbing, not theater.
Our mobile welding rigs bring repair welding to you, so downtime shrinks and panic fades. We care about plumbing systems, not paperwork.

NFPA-Compliant Sprinkler Retrofits
An NFPA-compliant sprinkler retrofit updates older fire sprinkler systems so they meet applicable National Fire Protection Association standards (think NFPA 13) — it’s about real protection, not checkbox theater, and yes, it can save you headaches with inspectors and insurers.
We handle NFPA-compliant retrofits for fire suppression systems, combining pipe fitting and pipe welding skills, plus welding for plumbing systems as needed. Our mobile welding services and welding repair services cut downtime; no drama.

Custom Pipe Fitting Trailer

We show up as your pipe fitter team, honest and fast, because downtime costs more than our jokes. Our mobile welder and portable welding services handle welds, taps, and fittings for sprinklers.
McMahan Industrial Services backs every job. You get pipe fitting and repair proficiency and welding for fire suppression systems, minus the drama.
