Pipe made McKeesport. The National Tube Works turned out steel pipe and tube on the Monongahela for roughly a century, employed generations of the city’s families, and gave McKeesport its nickname, Tube City. Under U.S. Steel the National Works remained one of the country’s major pipe producers until operations wound down in the 1980s. Those decades sit inside the industrial asbestos era, and former tube mill workers and their families are among Pennsylvania’s mesothelioma claimants today.
The product and the plant
Making pipe is hot, heavy work: heating steel, piercing and rolling it into seamless tube or forming and welding it, then finishing, threading, and testing. The National Works did this at enormous scale, with furnaces and reheating equipment, steam-driven machinery, and a powerhouse and boiler plant behind it all. As at every mill of its era, the heat-management materials are what put asbestos in the buildings.
The asbestos-era equipment list
The National Cancer Institute reports that asbestos was standard in insulation for boilers, steam lines, furnaces, and similar high-heat equipment until the late 1970s (NCI asbestos fact sheet). In a tube works that meant insulated steam piping across the plant, linings and heat-resistant patching on furnaces, gaskets and packing in valves and pumps, and protective cloth gear in hot areas. Maintenance was the exposure engine: stripping old pipe covering, relining furnaces, rebuilding pumps, and sweeping up afterward all released fibers into shared air.
McKeesport trades with likely exposure
- Furnace and heating crews in the pipe mills
- Rolling, piercing, and welding mill hands near insulated machinery
- Pipefitters, millwrights, and boiler house operators
- Bricklayers and laborers on reline and tear-out work
- Finishing, threading, and shipping crews sharing mill air
Family exposure counts too. The NCI notes that fibers traveled home on work clothes, and McKeesport’s mill households handled that laundry for decades.
Documenting a Tube City career is more feasible than families assume. Social Security earnings statements list employers year by year. The steelworkers’ union locals kept membership records. U.S. Steel pension and benefit files place workers in specific plants and, often, specific departments. And earlier McKeesport litigation left deposition testimony describing the mills’ products and practices, so a new case builds on an existing record rather than starting cold.
Across the river and up the valley
The National Works faced the Duquesne Works across the Monongahela, and McKeesport men also turn up in histories from the Clairton Coke Works a few miles upriver. Multi-plant careers were the valley’s norm, and each named site can add product manufacturers and trust claims to a case. The Pennsylvania asbestos exposure sites index lays out the full valley map.
Why the claim is still timely
Mesothelioma typically develops 20 to 50 years after exposure, per the NCI, so the plant’s final working generation is being diagnosed now. Pennsylvania generally allows two years from the date of diagnosis to file (42 Pa. C.S. § 5524). The employer’s fate is beside the point: claims target the makers and suppliers of the asbestos products used in the works, and many of those companies fund bankruptcy trusts that exist to pay exactly these claims.
The scale of that trust system is documented: the U.S. Government Accountability Office reported roughly 30 billion dollars set aside in asbestos bankruptcy trust funds (GAO-11-819). Tube works histories, spanning decades and many suppliers, commonly support claims against more than one of them.
What this means for your family
A McKeesport case starts with what the family remembers: the mill, the department, the rough years, the kind of work. It does not start with product names, because identifying the insulation and gasket brands present in the National Works during those years is the lawyer’s job, done through records developed over decades of Mon Valley litigation.
