Corrosion Protection of Super Duplex against Sulphuric Acid
Condition before blasting and coating Vessel after blasting and coating External after blasting and coating OVERVIEW: Critical minerals such as nickel are often processed in industrial environments where exposure to chemicals and by-products are far from conducive to corrosion prevention. Combatting the elements like acid rain and atmospheric corrosion can be detrimental to plant […]
Preventing Stress Corrosion Pitting
Site Layout before equipment setup Previously applied coatings delaminated Ammonia Absorber Circulation Tank OVERVIEW: The 304 stainless steel ammonia absorber and circulation tank experience temperatures of up to 100°C and an aggressive Chemical environment. The prevention of stress corrosion pitting was achieved in the heat affected areas by applying corrosion protection on the entire […]
Using 500 Series in Preventing Hang Up on Matcon Valve
During Inspection On Arrival Internals Coated Externals Complete OVERVIEW: Chemco’s Ceram-chem™ system was used to rebuild the internal profile of this valve, and coat to prevent future corrosion and abrasion. In addition, RP 500 creates a slippery surface preventing hang up and blockage issues, maximising the valve’s efficiency. INDUSTRY Mineral Processing ENVIRONMENT Coke breeze […]
Epo-chem™ 500 Series for Pump & Base
Pump with factory shop primer Completed coated pump Application of final coat Complete coating of pump, coupling guard, channel base frame and two pole motor OVERVIEW: Steel multi-stage pump assemblies in an 80°C corrosive aqueous ammonia environment required long term protection. The external coating system was required to act as a corrosion barrier for […]
Hot Air Impeller
Pre balanced coated fan RU 500 Low friction finish Completed coated and balanced fan using RS 500P & RU 500 OVERVIEW: The fabricated carbon steel fan came under attack from atmospheric moisture and abrasion due to crystalline quartz dust in the hot air fumes that it was extracting. This resulted in costly unplanned shut-downs and […]
Ventilation Fan
During Fabrication Application of primer by hand due to complexity View of fan on completion OVERVIEW: The fan required pressure washing every 3-6 months to prevent large amounts of build up. This build up was causing balancing issues and unnecessary bearing load. Chemcote was engaged to improve the efficiency of the fan, decrease problems […]
