Rare Earth Alloy Wear Resistant Casting Tube

High-performance Tube For Extreme Abrasive Environments

Rare earth alloy wear resistant casting tube delivers outstanding durability and protection against abrasion, corrosion, and impact in demanding industrial pipeline systems.

The Rare Earth Alloy Wear Resistant Casting Tube is a heavy-duty industrial component engineered for use in severe wear environments such as high-speed slurry, ash, and ore transportation. Made from advanced cast alloy steel enriched with rare earth elements—including cerium, lanthanum, and neodymium—this tube offers exceptional wear resistance, toughness, and thermal stability.

Rare earth alloy modification refines the grain structure of the steel, enhancing its hardness (typically 240–320 HB), impact resistance, and resistance to erosion, cracking, and high-temperature cycling. These characteristics make the tube ideal for conveying highly abrasive and corrosive media such as fly ash, mineral slurry, coal dust, and clinker under extreme pressure and temperature.

This product is widely used in:

The casting process ensures uniform wall thickness and dense structure, eliminating weak zones and internal defects. These tubes can be manufactured as straight lengths or shaped into elbows and custom fittings to accommodate complex piping layouts.

Also known as abrasion resistant alloy casting pipe, rare earth wear tube, or high-strength cast steel pipe, this product extends service life, reduces maintenance, and improves safety in critical industrial systems.

Sunny Steel provides full customization options including diameter, wall thickness, connection types (flanged, welded, threaded), and material certification. Engineering support and international delivery are available to ensure efficient integration into your pipeline system.

Rare Earth Alloy Wear Resistant Pipe

What is a Rare Earth Alloy Wear Resistant Pipe?

Rare Earth Alloy Wear Resistant Pipes are advanced industrial piping solutions made from high-strength rare earth alloy castings. These pipes are engineered to deliver exceptional resistance to abrasion, corrosion, and high temperatures.

Thanks to their superior durability, they are widely used in harsh environments such as:

  • Coal handling systems
  • Mining and ore transport
  • Thermal power plants
  • Cement and clinker conveying

Rare Earth Alloy Pipes significantly extend service life and reduce downtime, making them a cost-effective choice for abrasive material transport.

Material

Ceramic-lined pipes are known for their high hardness, wear resistance, thermal stability, and self-lubricating performance. Made from rare earth alloy steel and high-purity alumina ceramics, they offer superior performance in abrasive and high-temperature environments.

Ceramic-lined pipes are reinforced with anti-shedding alumina tiles, strong inorganic adhesives, and precision welding. This dual-layer structure ensures long-term performance under high-stress, corrosive, and abrasive conditions.

These pipes are designed for flexible installation, low maintenance, and cost-effectiveness, making them ideal for use in mining, thermal power plants, steelworks, and chemical industries.

PMI test of rare earth alloy pipes

PMI Test

High Hardness

Rockwell hardness of alumina ceramics reaches HRA80–90, second only to diamond and much higher than wear-resistant steel.

Wear Resistance

Alumina ceramics provide 266× the wear life of manganese steel and over 170× that of high chromium cast iron.

Thermal Stability

Withstands continuous service temperatures up to 1400°C, making it suitable for furnaces and kilns.

Low Friction

Smooth surface reduces flow resistance; surface roughness is 1/6 that of steel pipes.

Custom Shapes

Supports thick-walled, curved, and shaped designs to match various piping systems and wear zones.

Lightweight

With a density of ~3.6g/cm³, alumina ceramic pipes weigh half as much as steel, improving transport and installation efficiency.

ZG40CrMnMoNiSiRe Alloy Steel

This rare earth alloy steel contains chromium, molybdenum, nickel, and rare earth elements to enhance strength, toughness, and corrosion resistance.

Commonly used in boiler tubes, heat exchangers, and high-pressure pipelines, it withstands creep, corrosion, and thermal cycling in extreme service conditions.

While offering excellent performance, its specialized composition makes it better suited for heavy-duty applications rather than general use.

Abrasive Wear Solution

Abrasive wear is the most severe form of wear, occurring when hard particles cut or gouge metal surfaces—causing plastic deformation, scratches, and eventual erosion.

Allwey's new high-strength rare earth wear-resistant material is developed based on this principle, targeting the root cause of wear-related failures.

Core Advantages

Fundamentally solves leakage accidents (coal, oil, air, and ash leakage) that occur during the operation of coal crushing, grinding, and powder feeding equipment in:

Key Features of Rare Earth Alloy Wear-Resistant Pipe

Advanced multi-alloy design combining extreme wear resistance, corrosion protection, and ease of installation for pneumatic conveying, slurry pumping, and ash/slurry handling systems.

Abrasion Resistance

Under identical conditions, wear volume is only ~1/3 of high-manganese steel, delivering 2–3× longer service life than traditional wear-resistant materials.

Superior Corrosion & Heat Resistance

R-α carbide structure + high Cr + Mo + rare earth elements create a dense protective oxide film. Excellent performance in high-temperature, acidic, or corrosive environments. Boron increases surface hardness beyond carburizing limits while manganese improves fatigue strength.

Easy Installation & Maintenance
  • Cutting, bending, and flanging with standard tools
  • Flange or direct butt-welding to carbon steel pipe
  • High weldability and reliable disassembly
High Pressure Capability

Straight pipes withstand >6 kg/cm²
Hot-pressed elbows safely operate at >10 kg/cm²
No air leakage or material deviation in pneumatic systems.

Superior to Bimetallic & High-Cr Alternatives

Ideal for coal pulverizing, ash removal, slag discharge, dredge scrapers, spiral conveyors — environments where bimetallic composites fail.

Precision Manufacturing

Centrifugal casting + EPC vacuum suction process ensures high dimensional accuracy, uniform microstructure, and stable performance — even for complex shapes like spiral pipes and coal mixers.

Horizontal centrifugal casting process

Horizontal Centrifugal Casting Process of Rare‑Earth Alloy Wear‑Resistant Pipe

Rare‑earth alloy wear‑resistant pipes are produced using horizontal centrifugal casting. Molten alloy is poured into a spinning cylindrical mold (800–1,000 rpm), where centrifugal force distributes metal against the mold walls, forming a dense, uniform structure.

High‑integrity Tube Production

Ideal for long, seamless tubular parts like sleeves and pipes.

Defect Reduction

Centrifugal force pushes slag and porosity to the inner bore, resulting in a cleaner, stronger outer structure.

Directional Solidification

Solidification begins from the outer mold inward, enhancing metallurgical properties.

Flexible Dimensions

Wall thickness is controlled by metal volume; length is limited only by mold and facility size—up to 6 m or more.

This process delivers pipes with uniform density, refined grain structure, and high mechanical integrity—perfect for wear‑resistant, high‑temperature, and high‑pressure applications.

Industry Application

Designed for slurry transport, pneumatic delivery, and extreme industrial conditions, offering superior wear, heat, and corrosion resistance.

Abrasion Resistance

Only 1/3 the unit wear of high manganese steel under the same conditions. Service life is 2–3× longer, reducing replacement frequency.

Corrosion & Heat Resistance

Rare earths and Mo enhance high-temp and corrosion performance. Boron boosts hardness, while Mn increases fatigue resistance.

Convenient Installation
  • Easy cutting and welding with low-carbon steel
  • Modular design simplifies elbow and flange integration
  • Good field adaptability
High Pressure Resistance

Withstands up to 6–10 kg/cm² pressure. Special elbows made via hot pressing and precise welding avoid leakage or material diversion.

Special Material Capability

Ideal for parts where bimetallic pipes fail—e.g., dredge scrapers, coal mixers, spiral tubes—used widely in power generation systems.

Advanced Technology

Combines centrifugal casting, resin sand, and EPC vacuum casting for uniform structure, high precision, and long-term reliability.

Note on Fragility

While highly wear-resistant, the material has lower impact resistance. Handle with care during transport and installation to avoid damage.
