Wide range of components made of special tubing

Components based on round tubing

A wide range of stainless steel components can be produced on the basis of longitudinally welded stainless steel tubes. These include:

  • Exhaust systems
  • Outer shells for catalytic converters and diesel particulate filters
  • Filter housings
  • Fuel rails
  • Chassis structural components
  • Safety components (e.g. for airbags)
  • Tank filler necks
  • Heating distributors
  • Sanitary industry products
  • Heat exchangers
Components made from thin-walled tubes
