Chemical Plant Maintenance & Process Pipe Fabricationin Northwest Indiana & Chicagoland

What does SSI do for chemical plants?

We keep chemical processing equipment sealed, running and safe to work on. Our crews fabricate and install process pipe, rebuild pumps and gearboxes, retrofit aging equipment and respond 24/7 when something fails. We serve chemical plants across Northwest Indiana and Chicagoland from our shop in Portage.

The chemical processing industry requires precision and rigorous safety standards. Equipment handles hazardous materials, and a leak is a safety and environmental problem before it’s a production problem. That shapes how we plan every job.

How do you approach process pipe work in a chemical plant?

We approach process pipe as a planned job with as much work done in the shop as possible. Building spools in our Portage shop means better welding conditions, faster fit-up and less time working inside the unit.

A typical job runs like this:

1. Walk down. Review the line, the media, the drawings and the isolation plan with your team.
2. Fabricate. Build spools and supports in the shop to your spec and material.
3. Install. Isolate, remove the old section and fit the new one under your permits.
4. Inspect and test. Inspect the welds and support the testing your plant requires before startup.

See pipe fabrication and welding for more detail.

What equipment do you rebuild or retrofit?

We rebuild and retrofit the rotating and process equipment that keeps a chemical plant running. When parts are obsolete, our machine shop machines replacements so you aren’t stuck waiting on a lead time.

Equipment	Common problem	What we do
Process pumps	Seal leaks, bearing failure, worn impellers	Pump rebuild and alignment
Agitators and mixers	Gearbox wear, shaft and seal problems	Gearbox rebuild, repair and realignment
Motors and drives	Vibration, heat, early bearing failure	Laser alignment
Aging systems	Repeated failures, obsolete parts	Equipment retrofitting
Fans and collectors	Vibration, wear, airflow loss	Environmental systems service

Should you retrofit or replace aging chemical plant equipment?

Retrofit is often the better choice when the core of a system is sound but a few components keep failing. It usually costs less and takes less downtime than a full replacement. We assess the equipment on site, then tell you plainly which parts to upgrade and which to keep.

A retrofit can mean new machined parts, rebuilt pumps or gearboxes, modified piping and realigned drives. We used the same approach at a steel manufacturing facility in Gary, where a 3-week retrofit avoided a full system replacement. Read the Gary retrofit case study.

How do you handle safety on chemical plant jobs?

We treat safety as how the job gets done. Every job starts with a job hazard analysis (JHA). Our crews work under lockout/tagout, confined space, hot work and fall protection programs, and we follow your plant’s permits, isolation steps and protective equipment rules on top of our own. We are an ISNetworld member contractor and Avetta prequalified. Read more on our safety page.

What happens when something fails at 2 a.m.?

You call (219) 386-1506. The line is answered 24/7. Tell us what failed, the media involved and the site conditions. We’ll tell you how fast a crew can get there and what access and permits they will need. Our crews arrive ready to diagnose, and our shop can machine or fabricate parts when an OEM part isn’t available. See emergency repair.

Why do chemical plants call SSI?

Chemical plants call us because one contractor can fabricate the pipe, rebuild the pump, align the drive and retrofit the system. Fewer handoffs mean fewer people in the unit and a cleaner restart. No shortcuts, no excuses.
