Pickling & Passivation

Spiraweld Stainless Limited can chemically clean your stainless steel at our plant.  Services include cleaning wire or any other surface not suitable for mechanical cleaning.  We have a 10.5 metre long x 1.25m wide x 900mm deep bath.  We have the facility to clean large and small components. Components are placed directly into the bath or on a cradle and immersed in the nitric/hydrofluoric solution.

The benefits are:

  • Universal finish
  • Protection from tea staining and rusting
  • Cleans welds
  • Quick & cost effective
  • Able to clean inside where often mechanical cleaning cannot reach
  • Chemically treats the heat affected zones after welding
