OVERVIEW: Customer required long term corrosion protection for significantly damaged 25 year old asset. A quick turn-around was required to meet project milestone targets and was achieved with minimal disruption to rolling mill operations. Chemcote ensure all QA and critical tolerances were adhered to provide the desired solution. No damage was visible at the six month follow up, confirming that Chemcote’s solution will deliver long term protection against future deterioration
INDUSTRY
ENVIRONMENT
60-70ºC Recirculated quench water used to flush mill scale
SUBSTRATE
25 year old Mild Steel Substrate
CHALLENGE
Heavy duty internal and external repair and protection for aged asset in a corrosive environment. Internal pitting from high temperature and mill scale. External corrosion caused by leaking flanges. Critical tolerances testing required to ensure basket fit to orifice plate.
SCOPE
Pre-machine rebates on all flanges
Abrasive blast internals
Apply glassflake filled vinyl ester to coat internals
Conduct QA including confirmation of DFT and high voltage continuity testing
Repair and rectify defects
Apply 3 coats of specially chosen products to ensure heavy duty external corrosion protection
