Zirconia lined sleeve is a composite pipeline component that uses high-purity and high stability zirconia ceramics as the inner lining. It combines the excellent wear resistance, corrosion resistance, high temperature resistance, and anti scaling properties of zirconia ceramics with the excellent mechanical strength of metal pipelines, providing a long-term and reliable overall solution for material transportation in harsh industrial environments.
Product Overview and Core Advantages
Zirconia lined sleeve is an innovative composite structure pipeline, whose design core is to tightly embed or bond a high-density zirconia ceramic lining inside an outer pipe made of carbon steel or alloy steel. This structure fully utilizes the synergistic effect of the two materials and has the following irreplaceable core advantages:
- 究極の耐摩耗性
Data support: The Rockwell hardness (HRA ≥ 85) of zirconia ceramics is second only to diamond and silicon carbide, and its wear resistance is more than 20 times that of high chromium cast iron and more than 150 times that of manganese steel.
Mechanism: It can effectively resist erosion, abrasive wear, and micro cutting wear that occur during the transportation of powders, particles, and slurries, greatly extending the service life of pipelines under harsh working conditions. - Excellent corrosion resistance and high temperature resistance
Chemical inertness: Zirconia has excellent chemical stability against most acids, bases, salts, and organic solvents, and can withstand corrosive media with a wide range of pH values.
Thermal stability: Zirconia ceramics have a high melting point (about 2700 ℃), can work stably in high temperature environments for a long time, have excellent thermal shock resistance, and can adapt to temperature fluctuations in working conditions. - Ultra low friction coefficient and anti scaling properties
The ceramic inner wall surface is as smooth as a mirror, with an extremely low friction coefficient, significantly reducing material conveying resistance and saving energy consumption.
The smooth surface and hydrophobicity make it difficult for materials to adhere and accumulate, effectively preventing pipeline blockage and reducing maintenance downtime. It is particularly suitable for working conditions with viscous materials or easy scaling. - High structural strength and long lifespan
The metal outer tube provides excellent impact resistance and mechanical load resistance, ensuring the overall structural strength and safety of the pipeline system.
The direct benefits brought by comprehensive advantages are dozens of times longer pipeline service life, fundamentally reducing the full lifecycle cost of equipment.
Key industrial problems solved
Zirconia lined sleeve is not a universal pipeline, but a high-value solution for specific industrial pain points, which can effectively solve the following problems:
Production interruption caused by frequent replacement of pipelines: In the transportation of fly ash and mineral powder in mines, power plants, and cement plants, traditional steel pipes wear out extremely quickly, leading to unplanned shutdowns. The replacement cycle of zirconia lining pipes will be extended from several months to several years to ensure continuous production.
Product quality pollution issue: Metal debris generated by pipeline wear can contaminate products such as food, pharmaceuticals, and lithium battery materials. The chemical stability and high hardness of zirconia lining ensure the purity of the conveying medium.
High maintenance costs and safety risks: The risk of leakage of highly corrosive chemicals (such as acid and alkali slurries) is high, and maintenance work is dangerous and expensive. The excellent corrosion resistance of this product fundamentally enhances safety and economy.
Pipeline blockage and low efficiency issues: In the transportation of viscous slurry or easily crystallized materials, scaling on the inner wall of the pipeline can lead to a decrease in flow rate and an increase in energy consumption. Its smooth and non stick characteristics ensure smooth flow and maintain efficient system operation.
