Fabricated by cladding seamless steel pipes with a chromium carbide overlay via open-arc welding, this pipe offers internal and external protection, enhancing longevity in harsh industrial environments. It's customizable for specific applications, combining the strength of steel bases with the hardness of carbide alloys for superior performance over standard pipes.

CCO Pipe is engineered from a seamless steel base (e.g., Q235B/Q345B) overlaid with a C-Cr alloy layer, applied through automated welding for uniform coverage. This bimetallic design resists severe wear from slurries, dust, and high-velocity flows, making it suitable for both simple and complex installations. The overlay's carbide content (up to 50%) forms a protective matrix that withstands temperatures from -60°C to 800°C, ideal for demanding sectors where downtime is costly.

Manufacturing Process

The production emphasizes precision and durability:

1. Base Preparation: Start with seamless steel pipes for structural integrity.
2. Forming: Roll wear plates into cylindrical shapes to match pipe dimensions.
3. Overlay Cladding: Apply chromium carbide welding wire using open-arc welding in multiple passes, building a >3mm thick internal/external layer.
4. Finishing: Cool controlled to minimize stress cracks; cut to unlimited lengths per section, with options for custom drawings and beveling.

This process ensures a strong metallurgical bond, with minimal porosity and excellent weldability.

Key Features

• Wear and Impact Resistance: Hard carbide layer deflects abrasive particles and absorbs moderate shocks.
• Thermal and Corrosion Durability: Operates in extreme temperatures and pH ranges without degradation.
• Ease of Use: Simple to install, repair (e.g., crack patching), and maintain, similar to standard steel pipes.
• Customizability: Tailored thicknesses, lengths, and designs for bends or fittings.

Technical Specifications

The prowess of CCO pipe in corrosion protection stems from its multi-layered engineering, optimized for erosion resistance in demanding boiler and pipeline scenarios. The chromium-rich matrix not only deflects abrasive impacts but also passivates surfaces against oxidation and galvanic corrosion, forming a Cr₂O₃ protective film that thrives in hot, humid conditions. With overlay thicknesses exceeding 3mm—applied in uniform passes—this pipeline lining maintains concentricity, ensuring even flow distribution and reduced turbulence that exacerbates wear.

Advanced variants incorporate flux-cored wires for smoother deposition, minimizing porosity and enhancing bond strength (>8,000 psi). For boiler pipe shield in coal-fired plants, the pipe's tolerance to sulfidation—common in flue gas ducts—is bolstered by high Cr content (23-28%), outperforming standard AR steels in erosion-corrosion tests. Users seeking "boiler pipeline wear solutions" benefit from its moderate impact absorption via the ductile steel substrate, preventing spalling in cyclic loads up to 1,000 psi.

Customization elevates usability: Tailor internal/external cladding for dual protection, or add hybrid zones with tungsten carbide for ultra-abrasive spots. Field-repairable with standard welding rods, CCO pipes cut installation time by 50% compared to ceramic inserts, making them a practical upgrade for chromium carbide overlay applications in mining tailings or cement kilns.

These innovations position CCO pipe corrosion protection as a versatile shield, solving chronic degradation in erosion resistance-critical setups.
