Watsia Stage 2

Located approximately 16kms east south-east of Dongara the Watsia gas field is ranked on of the largest gas fields ever discovered onshore in Australia capable of producing 250 Tj/day

ICS International Corrosion Services are pleased to be tasked by Clough and Mitsui E&P to perform the post fabrication treatment of the stainless-steel spooling and supports.

The post fabrication treatment will be to pickle and passivate the stainless steel in compliance with ASTM A380 and A967.


  • Remove surface contaminants that would otherwise cause premature tea staining and corrosion.
  • Treat the heat affected areas that would otherwise be a point of corrosion.
  • Reform the passive/chromium layer that gives the stainless steel its corrosion resistant properties.
  • Treatment will be on all surfaces inside and out.


  • Increased durability and longevity which ties into sustainability.
  • Reduced tea staining and corrosion.
  • Increased corrosion resistance.
  • Reduced maintenance and cost of ownership.
  • Will enable the stainless steel to perform at its optimum best for longer. 

If durability longevity, low cost of ownership and maintenance are important factors pickling and passivation in compliance with ASTM A380 and A967 is critical to achieving these outcomes.
