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.
