Specialised Chemical Cleaning


Commissioning, Cleaning & Passivation

Employee and customer safety is our number one goal in any chemical cleaning exercise & we know that all injuries are preventable.

We continually train all Supervisors & Technicians to ensure a safe work environment each and every job. Complex industrial plants generally need to be cleaned & prepared for plant service, this enables long term reliable operation.

Cleaning processes CORE are involved with include:

  • removal of corrosion product HP steam lines to turbines to minimise steam blows

  • removal of oil and grease medium to high pressure steam plant prior to commissioning 
  • removal of corrosion product steam lines prior to commissioning
  • removal of oil and grease/passivation stainless steel vessels and pipework prior to commissioning

Once the work to be completed is understood & all necessary risk assessments & preparation completed, manpower, chemicals and equipment are mobilised to sites where the clean & passivation process begins. This involves however is not limited to:

  • the use of specialised pumps/tanks/hoses
  • site preparation of cleaning/passivation solutions as required
  • testing & recording cleaning/passivation solutions to ensure correct qualities maintained at all times
  • thorough washing/flushing of circuits as required
