Heat Exchange Pipe

The silicon carbide (SiC) heat exchanger pipe is a high-performance heat transfer component made from silicon carbide, a compound known for its exceptional properties.

Key Features:

• High-temperature corrosion resistance: SiC heat exchanger pipes can withstand extremely high temperatures up to 1800°C, making them suitable for operation in harsh environments.
• High strength: SiC maintains a high bending strength of 500-600 MPa even at 1400°C, ensuring durability and reliability at elevated temperatures.
• High thermal conductivity: The material's high thermal conductivity facilitates efficient heat transfer.

Applications:

• Petrochemical industry: Used for heat exchange of high-temperature flue gases, improving energy utilization efficiency.
• High-temperature alumina production: Helps cool high-temperature gases and protect equipment.
• Power, metallurgy, solar energy: SiC heat exchanger pipes are also widely used in these industries that handle high-temperature and corrosive fluids.

Manufacturing Process:

The production of SiC heat exchanger pipes involves multiple steps, including raw material preparation, substrate formation, wall thickness processing, heat exchanger core preparation, shell cladding, reinforcement application, sintering, surface treatment, and final inspection. These steps ensure the high quality and performance of the SiC heat exchanger pipes.

Classification and Quality:

• SiC is typically classified based on its content, with higher content and purity correlating to better physical properties. Products with a content of 95% to 98% are considered first-grade, while those with over 98% content are considered premium-grade.

In summary, the silicon carbide heat exchanger pipe offers excellent high-temperature corrosion resistance, high strength, and high thermal conductivity, making it a reliable solution for various industrial applications requiring heat exchange in harsh environments.
