We are Cedar Rapids' leading pipe‑fitting provider for fire suppression systems, specializing in corroded black pipe thread repairs, trailer‑mounted pipe threading and on‑site welding.

At McMahan Industrial Services, we deliver rapid diagnostics, 24/7 emergency mobile response and free site‑visit estimates — bluntly: no surprises, just fixes. Our crew works fast, honestly and we're oddly proud of our neat welds. We offer transparent pricing with clear timelines.

Corroded Black Pipe Threads

When corroded black pipe threads seize up in a fire suppression system, things stop being theoretical and start getting urgent — and messy.

We’ve seen seized threaded pipe ruin schedules and cause leaks. We respond fast with pipe fitting, pipe welding, repair welding, and welding for plumbing systems — even mobile welding services.

We’ll assess corrosion, recommend black pipe replacements or thread repair, and explain options. You’ll get honest timing and costs. Our job is reliable fixes, no fluff — just steady, competent work you can rely on. Stainless steel provides corrosion resistance and is a more durable alternative for your needs.

1. Rapid on-site evaluation

2. Targeted repair or replacement

3. Preventive follow-up

Trailer-Mounted Pipe Threading

Often, we roll up to a job with our trailer-mounted pipe threading rig and cut into the problem — literally.

We do trailer-mounted pipe threading, pipe fitting, and repair welding on-site so you don't wait. Our mobile welding trucks bring welding for fire suppression capability, custom fabrication tools, and industrial services experience.

We care about precision, speed, and not screwing up your shutdowns. Version: we measure, thread, weld, and leave systems ready — no drama, just reliable work you can count on.

1. Fast on-site threading

2. Precise fit, minimal downtime

3. Integrates with mobile welding and custom fabrication

24/7 Emergency Mobile Response

Because shutdowns don't care about business hours, our Emergency Mobile Response team rolls up with trailer-mounted pipe threading rigs and mobile welding trucks to get your fire suppression systems back in shape.

We show up fast, diagnose, and fix leaks or breaks—no drama, results. Our pipe welder manages welding for plumbing and welding for industrial equipment on site.

We offer repair welding and portable welding services so you can restart operations. You’ll get honest timing, clear pricing, and skill. No fluff.
