High - Temp Resistant & Corrosion - Proof Pressureless Sintered SiC Heat Exchange Tube for Industrial Furnaces
Description:
Manufactured through automated extrusion molding and sintered in vacuum high-temperature furnaces (2100-2200°C), our SiC heat exchange tubes deliver superior heat transfer efficiency – the optimal solution for Extreme Operating Conditions.
Typical application:
Pressureless sintered silicon carbide (SSiC) heat exchange tubes are mainly used as core heat transfer components in shell-and-tube heat exchangers, suitable for extreme industrial conditions.
Application Fields:
1. Petrochemical: High-temperature cracking furnaces; Sulfuric acid concentration systems
2. Energy: Waste heat recovery boilers; Nuclear reactor cooling circuits
3. Environmental: Flue gas scrubbing systems; Hazardous waste treatment
4. Metallurgical: Non-ferrous metal smelting; Molten salt heat transfer
Feature:
1. Exceptional High-Temperature Stability
2. Superior Corrosion Resistance
3. High Thermal Conductivity
4. Low Thermal Expansion
5. Excellent Wear Resistance
6. High Heat Transfer Efficiency
