Product Description
Foster Wheeler Corporation designed and manufactured a broad line of closed feedwater heaters — horizontal and vertical shell-and-tube heat exchangers installed in utility and industrial regenerative-cycle steam plants to preheat boiler feedwater using extraction steam. Foster Wheeler feedwater heaters were installed across U.S. electric utility fossil and nuclear stations, refinery cogeneration plants, chemical-plant powerhouses, and Navy shipboard propulsion plants.
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Foster Wheeler feedwater heaters were originally shipped, and were routinely serviced, with compressed asbestos sheet gaskets and asbestos-filled spiral-wound gaskets at multiple sealing surfaces:
- Bolted manway covers on shell and channel sections
- Channel-cover flanges on the tube-side inlet/outlet ends
- Shell-side and head flanges on horizontal heaters
- Steam-inlet nozzle flanges at the extraction-steam connection
- Vent, drain, and drip connection flanges across the drain-cooler and desuperheating zones
Foster Wheeler has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
Workers Exposed
- Boilermakers breaking out and re-gasketing manway covers during heater inspections
- Pipefitters (UA members) replacing extraction-steam and feedwater flange gaskets
- Millwrights and maintenance mechanics during tube-bundle pulls and heater retubes
- Insulators stripping and re-installing removable insulation blankets over gasketed joints
- Navy machinist’s mates and hull technicians servicing shipboard heater gasketing
Gasket removal typically involved scraping, wire-brushing, and grinding hardened compressed asbestos residue off flange faces — an activity plaintiffs allege released respirable chrysotile fiber into the immediate work area, particularly in confined heater bays with limited ventilation.
