Welded Tubes

Welded Hot and Cold Rolled Pipes

from hot or cold strip – they are suitable for construction, structural and mechanical engineering purposes, threading and welding, for thermal and pressure devices and piping for gas and flammable substances.

Categories according to the type of welding and production:

  • ERW - longitudinally welded tubes/pipes, electric resistance welding without filler material
  • HFW/HFI - longitudinally welded tubes/pipes, high frequency welding and high frequency induction without filler material
  • SAWL -  longitudinally welded tubes/pipes, submerged arc welding in a protective atmosphere with filler material
  • SAWH  - spiral (helical) welded tubes/pipes, helically submerged arc welded in a protective atmosphere with filler material
