CAS No. : 1344-28-1
Alumina ceramic tubes are made using isostatic pressing technology. Their exceptional insulation, wear resistance, pressure resistance, corrosion resistance, and heat resistance make them widely applicable in metallurgy, power generation, steel production, coal mining, mining, and chemical industries. They serve as wear-resistant and corrosion-resistant materials for material conveyance equipment and liquid flow surfaces within pipelines, handling abrasive particulate materials such as pulverized coal, ash, sand, gravel, molten aluminum, and corrosive media. Large-diameter alumina ceramic tubes are available with diameters reaching up to 1000mm and wall thicknesses up to 70mm.
Product Characteristics:
Alumina ceramic tubes feature exceptional high-temperature resistance, wear resistance, and corrosion resistance. They are lightweight with good mechanical strength and insulation properties, and can be customized and molded to meet customer requirements.
