Our specification range is designed to meet international standards including ASTM, DIN, and JIS. The outer steel pipe is typically sourced from high-grade carbon steel or stainless steel depending on the external environment's corrosivity. For the inner lining, we offer various ceramic geometries: mosaic tiles, hexagonal tiles, and integrated ceramic sleeves. The bonding agent used is a high-strength epoxy or inorganic adhesive capable of maintaining its structural bond even under extreme thermal cycling. We also provide customized flange dimensions and welding prep ends to ensure seamless integration into your existing infrastructure. Every batch is verified through a 100% inspection process covering wall thickness, concentricity, and bond strength.
Industrial Applications
Our ceramic lined pipes are widely deployed across industries where abrasive materials are transported at high velocities. In the Power Generation sector, they are indispensable for pulverized coal injection lines and bottom ash removal systems. The high-velocity impact of coal particles can quickly erode standard piping, but our alumina lining remains unaffected. In the Mining and Mineral Processing industry, these pipes handle iron ore slurries, gold mine tailings, and copper concentrates. The chemical stability of alumina also makes these pipes suitable for the Cement Industry, specifically for conveying raw meal, silica, and clinker. Steel Mills utilize our pipes in their sintering plants and blast furnace dust extraction systems. Furthermore, the Lithium Battery Material industry has recently adopted our ceramic solutions to prevent metallic contamination during the transport of cathode and anode powders. Because our ceramics are chemically inert, they ensure the purity of the transported medium while resisting the mechanical wear of the powder flow.
Manufacturing Advantages
- Extreme Wear Resistance: With a Mohs hardness of 9, second only to diamond, our ceramic lining outperforms hardened steel and manganese alloys.
- Corrosion Resistance: High-purity alumina is naturally resistant to acids, alkalis, and organic solvents, making it ideal for mixed-media transport.
- Smooth Internal Surface: The low friction coefficient of ceramic liners prevents material buildup and reduces pumping energy costs by improving flow dynamics.
- Thermal Stability: Our composite pipes can operate continuously at temperatures up to 800°C without loss of mechanical properties or liner detachment.
- Lightweight Design: Compared to heavy cast stone or thick-walled alloy pipes, our ceramic-lined steel pipes are lighter and easier to install, reducing labor costs.
- Custom Engineering: As a direct manufacturer, we provide tailored designs, including complex elbows, Y-pieces, and reducers, all fully lined with ceramic.
