DeLaval Turbine: Asbestos Products, Occupational Exposure, and Legal History

DeLaval Turbine was an American industrial manufacturer whose turbine equipment was widely used in power generation, marine propulsion, and heavy industrial facilities throughout the mid-twentieth century. According to asbestos litigation records, workers who installed, operated, and maintained DeLaval turbine equipment during the peak decades of industrial asbestos use — roughly the 1940s through the early 1980s — may have encountered asbestos-containing components in the course of their work. This reference article is intended to help workers, their families, and legal professionals understand the historical context of potential asbestos exposure associated with DeLaval Turbine equipment.

Company History

DeLaval Turbine was part of a broader industrial lineage tracing back to the pioneering turbine engineering work associated with the De Laval name in the late nineteenth century. The American company bearing the DeLaval Turbine name operated as a manufacturer of steam turbines and related rotating equipment for industrial and marine applications throughout the mid-twentieth century.

DeLaval turbines were installed in a wide range of settings: fossil fuel and nuclear power generation plants, shipyards and naval vessels, petrochemical refineries, paper mills, and other heavy manufacturing facilities. These installations placed the company’s equipment at the heart of the American industrial economy during the postwar period, when asbestos use in thermal and mechanical insulation was at its peak.

The company underwent various corporate transitions over its history, including ownership changes and potential successor relationships that can be relevant to legal claims. Researchers and attorneys evaluating exposure histories involving DeLaval Turbine equipment should investigate the full corporate lineage, as successor liability and indemnification arrangements may affect the current status of any legal claims.

DeLaval Turbine is understood to have ceased incorporating asbestos-containing materials into its products by approximately the early 1980s, consistent with broader industry-wide transitions that followed increased regulatory scrutiny and mounting litigation during that period.

Asbestos-Containing Products

Court filings document allegations that DeLaval Turbine manufactured and supplied industrial steam turbines and associated equipment that incorporated asbestos-containing materials as component parts. Because steam turbines operate at extremely high temperatures and pressures, thermal insulation was a critical design requirement — and for much of the twentieth century, asbestos-based materials were the industry standard for that purpose.

Plaintiffs alleged that asbestos-containing materials associated with DeLaval Turbine equipment appeared in several forms:

Internal insulation and packing materials. Steam turbines require sealing and packing materials around valve stems, shaft seals, and other dynamic components. For much of the postwar era, these packing materials commonly contained asbestos fibers, which provided both thermal resistance and mechanical durability under high-pressure steam conditions.

Gaskets. According to asbestos litigation records, turbine systems manufactured and sold during this period routinely incorporated asbestos-containing gaskets at flanged connections, casing joints, and associated piping interfaces. Gasket replacement was a routine maintenance task, requiring workers to scrape, grind, or otherwise remove old gasket material — activities known to release respirable asbestos fibers.

External insulation. Large industrial turbines were typically covered with block, blanket, or spray-applied insulation to conserve thermal energy and protect workers from surface heat. Court filings document that such insulation systems, whether applied by the turbine manufacturer, a contractor, or an insulation supplier, frequently contained asbestos through the 1970s.

Turbine casings and associated piping. In some industrial configurations, asbestos-containing materials were applied directly to turbine casings or to the connecting steam lines and exhaust systems as part of the overall thermal management of the installation.

It should be noted that documentation of specific product formulations for DeLaval Turbine equipment is not always complete in the historical record. Plaintiffs alleged that asbestos content in these components was not always disclosed to workers or facility operators, and that safety warnings were absent or inadequate. These are allegations made in the context of civil litigation; no findings of liability against DeLaval Turbine should be inferred from the above description without reference to the specific legal record.

Occupational Exposure

The populations most likely to have encountered asbestos in connection with DeLaval Turbine equipment were those working in close proximity to the equipment during installation, routine maintenance, overhaul, and repair operations.

Power plant workers. Steam turbines are the central generating equipment in thermal power plants. Operators, maintenance technicians, and millwrights who worked in boiler and turbine rooms at coal, oil, gas, and nuclear generating stations may have been exposed to asbestos-containing insulation and gasket materials during routine inspections and maintenance shutdowns.

Shipyard workers and merchant mariners. DeLaval turbines were used in naval and commercial marine applications. Machinists, pipefitters, and engineers who worked in confined engine rooms and below-decks spaces — where ventilation was limited — may have encountered particularly concentrated asbestos fiber levels during maintenance and repair of turbine components.

Petrochemical and refinery workers. Large refineries and chemical plants used steam turbines to drive compressors and pumps. Instrument technicians, pipefitters, and general maintenance workers at these facilities may have disturbed asbestos-containing materials when accessing turbine components.

Millwrights, pipefitters, and insulators. Tradespeople responsible for the installation and insulation of large turbine systems were among those most directly exposed. Cutting, fitting, and finishing asbestos insulation products around turbine casings and steam lines could generate significant quantities of airborne asbestos dust.

Navy veterans. The U.S. Navy made extensive use of steam turbines aboard ships, and DeLaval-manufactured equipment appeared in a number of naval vessel applications. Veterans who served in engineering ratings aboard ships during the 1940s through the 1970s and who worked around turbine machinery may have encountered asbestos-containing materials in that context.

According to asbestos litigation records, workers in these trades and industries who were exposed to asbestos over prolonged periods faced elevated risk of developing asbestos-related diseases, including mesothelioma, asbestosis, and lung cancer. The latency period for these diseases — often 20 to 50 years from first exposure — means that workers exposed to asbestos in the 1950s, 1960s, and 1970s may still be receiving diagnoses today.

It is well established in occupational medicine and epidemiology that there is no safe level of exposure to asbestos fibers. Even intermittent or so-called “bystander” exposures — such as those experienced by workers in the vicinity of insulation work without directly handling materials themselves — have been associated with asbestos-related disease in clinical and legal contexts.

Trust Fund / Legal Status

DeLaval Turbine is classified as a Tier 2 manufacturer for purposes of this reference site. This means the company has been named as a defendant in asbestos-related civil litigation in the United States, but no asbestos bankruptcy trust fund has been established in connection with DeLaval Turbine or its identified corporate successors.

According to asbestos litigation records, DeLaval Turbine has been named in personal injury and wrongful death lawsuits filed by workers who alleged exposure to asbestos-containing materials associated with the company’s turbine equipment. Court filings document claims brought by individuals diagnosed with mesothelioma, asbestosis, and related conditions who identified DeLaval Turbine equipment at their worksites.

Because there is no dedicated asbestos trust fund associated with DeLaval Turbine, individuals seeking compensation for asbestos-related illness linked to this manufacturer’s products must pursue claims through the civil litigation system rather than through a streamlined trust fund claims process.

Persons evaluating potential claims should be aware of the following:

• Statutes of limitations for asbestos claims vary by state and typically run from the date of diagnosis or the date on which a claimant knew or reasonably should have known of the asbestos-related nature of their illness. Consulting with an asbestos attorney promptly after diagnosis is important.
• Corporate successor research is often necessary in cases involving DeLaval Turbine, as the company’s ownership and corporate structure changed over time. An attorney experienced in asbestos litigation can investigate the current legal entity, if any, responsible for claims against this manufacturer.
• Multi-defendant claims are common in asbestos litigation. Workers who encountered DeLaval Turbine equipment at their jobsites often worked with equipment and materials from numerous manufacturers. Claims may be brought against multiple defendants simultaneously, and separate trust fund claims may be filed against other companies (such as insulation manufacturers) that were also present at the same worksites.

Summary

DeLaval Turbine manufactured industrial steam turbines that were installed in power plants, ships, refineries, and other heavy industrial facilities from the mid-twentieth century through approximately the early 1980s. According to asbestos litigation records, these turbines incorporated or were used in conjunction with asbestos-containing insulation, gaskets, and packing materials that could release hazardous fibers during installation, maintenance, and repair. Workers including power plant technicians, millwrights, pipefitters, shipyard workers, and Navy veterans may have been exposed.

DeLaval Turbine has been named in asbestos civil litigation but has no established asbestos bankruptcy trust fund. Individuals diagnosed with mesothelioma, lung cancer, or asbestosis who believe their condition may be linked to DeLaval Turbine equipment should consult with an attorney experienced in asbestos exposure claims to evaluate their legal options.
