The specifications of our 95 alumina patch pipes are engineered to meet the highest international standards. We offer various patch shapes, including square, hexagonal, and rectangular, depending on the pipe's curvature and diameter. The steel pipe itself is manufactured according to ASTM or DIN standards, with wall thicknesses calculated based on the internal pressure requirements of your system. A critical specification of our product is the adhesive layer; we use proprietary high-toughness epoxy resins for standard temperatures and specialized inorganic ceramic glues for high-temperature applications. This ensures that even under thermal cycling, the patches remain firmly attached. We also provide "weld-on" patches, which feature a central hole for plug welding, offering a mechanical-chemical dual bond for high-vibration environments. All technical parameters, including ceramic density and compressive strength, are verified in our on-site laboratory, and we provide detailed Material Test Reports (MTR) for every delivery. We can accommodate pipe diameters from DN100 up to DN3000, making this one of our most flexible product lines.
Industrial Applications
Our 95 alumina ceramic patch pipes are the workhorses of the Power Generation industry, specifically in pulverized coal transport lines and ash handling systems. The high-velocity impact of coal particles is easily mitigated by the 95% alumina surface. In the Cement Industry, these pipes are used for conveying raw meal, clinker, and finished cement, where abrasion is constant and intense. Steel Mills utilize our patch pipes in their dust removal systems and sintering plants to handle hot, abrasive dust. Furthermore, the Mining and Metallurgy sector relies on these pipes for dry powder transport and tailings disposal. They are also highly effective in the Pulp and Paper industry for handling wood chips and abrasive fillers. Because the patches can be applied to almost any shape, they are ideal for custom-engineered Cyclones, Hoppers, and Chutes. In the Lithium Battery sector, these pipes provide a wear-resistant path that prevents metallic contamination of sensitive cathode materials. Their versatility makes them suitable for any process involving the pneumatic or hydraulic transport of abrasive solids at moderate to high speeds.
Manufacturing Advantages
- Cost-Efficiency: Provides superior wear protection at a lower price point than zirconia-toughened or silicon carbide alternatives.
- Geometric Versatility: The patch method allows us to line any shape, from simple elbows to complex multi-port manifolds.
- Easy Maintenance: Individual patches can be replaced if localized damage occurs, extending the total life of the steel structure.
- Exceptional Hardness: The 95% Alumina content ensures a Mohs hardness of 9, significantly outperforming hardened steel and alloy liners.
- Staggered Joint Design: Our factory's unique layout prevents the "river-wear" effect, ensuring uniform erosion across the entire surface.
- Thermal Adaptability: With various bonding options, our patch pipes can operate in environments ranging from cryogenic temperatures to 750°C.
