Ceramic Tubes
Cerval Industries specializes in manufacturing high-grade ceramic tubes tailored for demanding industrial applications. With a steadfast focus on quality, precision, and innovation, we utilize premium materials such as Alumina (Al2O3), Zirconia (ZrO2), and Silicon Carbide (SiC). These materials offer exceptional mechanical strength, thermal stability, and resistance to wear and corrosion, making our tubes ideal for high-temperature furnaces, electrical insulation, chemical processing, and mechanical components. Our advanced manufacturing process begins with meticulous material selection and advanced powder processing to achieve uniform particle size distribution. Tubes are shaped using precision extrusion or isostatic pressing methods, ensuring consistent dimensions and structural integrity. High-temperature sintering enhances mechanical strength, followed by precise machining and rigorous quality control checks. Customization is central to our service, allowing us to meet unique specifications with tailored solutions and technical support.
Available in a wide range of specifications—including outer diameters from 1 mm to 100 mm, inner diameters from 0.5 mm to 95 mm, and customizable lengths up to 1000 mm—our ceramic tubes uphold rigorous mechanical property standards.
