Performance Characteristics

· The lithium battery industry's hot-selling wear-resistant Alumina ceramic lined pipe uses a high-purity Alumina ceramic lining with a hardness of over HRA90. Its wear resistance far exceeds that of ordinary steel pipes, and it can effectively cope with the high-speed erosion of lithium battery powder materials, reducing the frequency of pipe replacement by 90%.

· Strong Corrosion Resistance: The ceramic layer is chemically stable and resistant to 99% of acids, alkalis, and halogen gases, with the exception of hydrofluoric acid. This prevents metal ion leaching and contamination of raw materials, ensuring the purity of battery materials and improving battery consistency and safety.

· Smooth Inner Wall: The smooth inner wall of the ceramic-lined pipe reduces material adhesion and blockage, ensuring smooth conveying. It also facilitates cleaning and effectively prevents material residue and cross-contamination.

· Excellent Thermal Shock Resistance: With a low thermal expansion coefficient (e.g., alumina ceramic has a thermal expansion coefficient of up to 3.0×10⁻⁶/K), it can operate stably in environments ranging from -40°C to 120°C, and can withstand the temperature fluctuations experienced during lithium battery production. · Clean and pollution-free: Zero metal ion precipitation meets semiconductor-grade cleanliness requirements, effectively isolates the conveying medium from contact with the outer steel pipe, and is highly effective in isolating metal contamination in the lithium battery industry.

Application Scenarios

Wear-resistant Alumina ceramic-lined pipes are widely used in lithium battery production. On lithium battery positive electrode material production lines, from raw material delivery, loading, batching, mixing, sintering, to final packaging, each stage is connected by pipes into a closed conveying system. Wear-resistant alumina ceramic-lined pipes can be used for material conveying in these stages, effectively ensuring material purity and stable delivery, while reducing pipeline maintenance and replacement costs.

Maintenance Process

1. Preparation: Procure materials, commission equipment, arrange construction personnel, and connect power and air sources.

2. Surface Cleaning: Effectively remove dust, dirt, loose rust, and other debris.

3. Grinding: Use an angle grinder to treat the pipe surface. Ensure that the pipe surface is free of loose particles such as loose rust. Operation is strictly prohibited in environments with humidity exceeding 85%. 4. Isolation Measures: After removing debris, place the pipe in a dry environment to prevent dust contamination.

5. Ceramic Gluing: Mix component A and component B in the correct proportions. After mixing thoroughly, apply the ceramic. Ensure the application is even, with no loose patches or protrusions. The wear-resistant ceramic layer should have a smooth surface, with gaps between the tiles less than 0.4mm, and the joints should be smooth and even.

6. Welding: After gluing the hardware, place it into the hole in the Ceramic Lining. Use a welder to weld the metal around the entire circumference, then adhere the metal cap to the surface of the hardware.

7. Self-Inspection: After applying the ceramic lining, perform a self-quality inspection, re-process any unsatisfactory areas, and then perform another self-inspection.

Operational Procedure

1. Pre-Installation Inspection: Check that the pipe specifications and models meet the requirements, check for defects such as cracks or peeling on the ceramic lining, and check for deformation or corrosion on the metal outer layer.

2. Pipe Connection: Follow the appropriate specifications based on the pipe connection method, such as flange connection or welding. When making flange connections, ensure the flange surfaces are clean, the gaskets are properly installed, and the bolts are tightened evenly. When making welded connections, use appropriate welding techniques to avoid damaging the ceramic lining.

3. System Commissioning: After installation, commission the entire system to check for proper sealing and conveying performance.

4. Daily Operation: During operation, carefully observe the pipeline's operation for abnormal vibration, noise, leaks, and other signs. Regularly inspect and maintain the pipeline.

5. Shutdown Maintenance: When the system is shut down, perform a comprehensive inspection and maintenance of the pipeline, including cleaning any residual material inside the pipeline and inspecting the ceramic lining for wear.

Operational Instructions

1. Avoid Hard Object Impact: During installation, operation, and maintenance, avoid impact with hard objects to prevent damage to the ceramic lining.

2. Control the Conveying Medium: Strictly control the conveying medium's temperature, pressure, pH, and other parameters in accordance with the pipeline's design requirements to avoid exceeding the pipeline's tolerances. 3. Regular Pipeline Cleaning: Clean the pipes regularly to prevent material accumulation and scaling, which can affect pipe performance and service life.

4. Note the Installation Sequence: When installing pipes, follow the correct installation sequence to avoid incorrect connections or loose installation.

Transportation Precautions

1. Packaging and Protection: Plastic caps should be placed on both ends of a single pipe to prevent damage to the ends. The pipes should be wrapped with multiple layers of bubble wrap or other cushioning material and then packaged in high-strength woven bags or wooden boxes. Critical areas of the ceramic lining, such as elbows and reducers, should be padded with additional cushioning materials such as foam sheets or sponges and secured with tape.

2. Loading Requirements: Transport should be carried out using a flatbed or low-bed truck. The truck bed should be flat and equipped with rubber or wooden pads to minimize direct contact and vibration between the pipes and the truck bed. Pipes should be stacked flat, generally no more than two layers high. Rubber spacers or wooden boards at least 5mm thick should be placed between layers to prevent the upper pipe from squeezing the ceramic lining of the lower pipe. 3. Securing Measures: Secure the pipe to the vehicle using steel wire rope or nylon straps. Secure the pipe at both ends and in the middle of the pipe. Rubber pads should be placed where the fixing points meet the pipe to prevent damage during the securing process. Each pipe should have at least three fixing points to prevent slipping and collisions during transportation.

4. Environmental Requirements: Protect the pipe from direct sunlight and rain during transportation. If transported in rainy weather, cover it with a tarpaulin that completely covers the pipe and securely fasten it with ropes. Also, avoid transporting the pipe with corrosive substances such as acids and alkalis to prevent corrosion.

5. Transport Speed: Control the vehicle speed during transportation. Avoid sudden braking and sharp turns. Maintain a steady driving position to minimize vibration and impact on the pipe. Slow down when passing over bumpy roads to prevent severe vibration that could cause the ceramic lining to dislodge or become damaged.
