High-purity corundum and mullite refractories for gasifiers, crackers and FCC units.
Petrochemical service is severe under high temperature and pressure with slag and chemical attack. The company supplies corundum, chrome-corundum and mullite castables and precasts for gasifiers, crackers and FCC risers/reactors, meeting high-purity, erosion-resistance and monolithic placement requirements.
