🔧 Asbestos-Containing Pipe Systems and Equipment Used by Illinois Pipefitters
For much of the twentieth century, Illinois pipefitters routinely worked around asbestos-containing insulation, piping systems, boilers, pumps, valves, turbines, and mechanical equipment. Because steam and process piping operated under extremely high temperatures and pressure, manufacturers relied on asbestos to reduce heat loss, improve efficiency, and protect workers from burns.
As a result, pipefitters experienced repeated occupational asbestos exposure while installing new piping systems, repairing leaks, replacing valves, rebuilding pumps, performing plant shutdown maintenance, and renovating older industrial facilities.
Common asbestos-containing products pipefitters encountered included:
- Pipe insulation
- Pipe covering
- Pipe lagging
- Boiler insulation
- Thermal cement
- Block insulation
- Elbow insulation
- Valve packing
- Pump packing
- Flange gaskets
- Mechanical gaskets
- Expansion joints
- Heat shields
- Fireproof cloth
- Rope insulation
- Pipe wrap
- Mechanical seals
- Turbine insulation
- Heat exchanger insulation
- Fire blankets
Many of these materials remained in Illinois factories, refineries, hospitals, schools, commercial buildings, and power plants for decades before maintenance or renovation projects disturbed them.
Pipefitters who also worked on commercial construction projects should review our Illinois Construction Workers Mesothelioma page for additional occupational exposure information.
💨 Steam Pipes and Pipe Insulation
Steam piping represented one of the greatest sources of asbestos exposure for Illinois pipefitters.
Before the early 1980s, nearly every commercial and industrial steam system contained asbestos insulation.
Common asbestos-containing pipe products included:

Pipefitters should focus on identifying the facilities where they worked, the piping systems they maintained, and the mechanical equipment they serviced rather than attempting to remember every manufacturer or product by name.
🩺 Asbestos-Related Diseases Among Illinois Pipefitters
For decades, Illinois pipefitters were exposed to asbestos while installing, repairing, maintaining, and replacing steam systems, industrial piping, boilers, pumps, valves, heat exchangers, and other mechanical equipment. Because asbestos-related diseases often take decades to develop, many pipefitters did not experience symptoms until 20 to 50 years after their occupational exposure.
The most common asbestos-related diseases include:
- Mesothelioma
- Asbestos lung cancer
- Asbestosis
- Pleural plaques
- Pleural thickening
- Other asbestos-related respiratory diseases
Even pipefitters who experienced relatively short periods of asbestos exposure may later develop serious illnesses. Anyone who worked as a pipefitter should inform their healthcare providers about their history of working around asbestos-containing pipe insulation, boilers, and industrial equipment.

🎗️ Mesothelioma
Mesothelioma is a rare and aggressive cancer caused almost exclusively by asbestos exposure. The disease develops after microscopic asbestos fibers become trapped within the lining surrounding the lungs, abdomen, heart, or testes. Over many years, these fibers can cause inflammation, scarring, and cellular damage that may eventually lead to cancer.
Former Illinois pipefitters diagnosed with mesothelioma often worked as:
- Industrial pipefitters
- Steamfitters
- Maintenance pipefitters
- Construction pipefitters
- Power plant pipefitters
- Refinery pipefitters
- Chemical plant pipefitters
- Commercial pipefitters
- Mechanical contractors
- Journeyman pipefitters
- Apprentice pipefitters
- Union pipefitters
- Boiler piping specialists
- Mechanical installers
- Plant maintenance mechanics
- Utility pipefitters
- Hospital maintenance pipefitters
- Pipe welding specialists
- Industrial maintenance technicians
- Mechanical maintenance workers
Common symptoms include:
- Shortness of breath
- Persistent cough
- Chest pain
- Fatigue
- Unexplained weight loss
- Fluid around the lungs
Because these symptoms often resemble more common respiratory illnesses, mesothelioma is frequently diagnosed only after the disease has advanced.
🫁 Asbestos Lung Cancer
Long-term occupational asbestos exposure significantly increases the risk of developing lung cancer. Pipefitters who routinely removed pipe insulation, repaired steam systems, rebuilt pumps, replaced valves, and maintained boilers may have inhaled asbestos fibers throughout their careers.
Common symptoms include:
- Persistent cough
- Chest pain
- Wheezing
- Coughing up blood
- Shortness of breath
- Hoarseness
- Fatigue
- Unexplained weight loss
Workers who both smoked cigarettes and were exposed to asbestos generally face a substantially greater risk of developing lung cancer than workers exposed to either risk factor alone.
🌬️ Asbestosis
Asbestosis is a chronic lung disease caused by inhaling asbestos fibers over an extended period of time. Once trapped inside the lungs, these fibers create permanent scar tissue that reduces lung function and makes breathing increasingly difficult.
Common symptoms include:
- Progressive shortness of breath
- Dry cough
- Chest tightness
- Fatigue
- Reduced exercise tolerance
Although there is no cure for asbestosis, early diagnosis and ongoing medical care may help manage symptoms and improve quality of life.
