Pressureless Sintered SiC Heat Exchange Tubes | High-Temp & Corrosion Resistant

Product Description

Our pressureless sintered silicon carbide (SSiC) heat exchange tubes are engineered for extreme industrial environments. Manufactured through automated extrusion and sintered at ultra-high temperatures (2100-2200°C), they deliver unmatched thermal performance, exceptional corrosion resistance, and long-term structural stability. As the core component in shell-and-tube heat exchangers, they are the superior choice for maximizing efficiency and minimizing downtime in the most demanding applications.

Key Material Properties & Performance Data

The following table details the superior physical and thermal properties of our SSiC material that guarantee reliable performance.

Why Choose Our SiC Heat Exchange Tubes?

• Superior Corrosion Resistance: Withstands harsh acids, alkalis, and solvents, making it ideal for aggressive chemical processes where metals and alloys fail.

• Exceptional High-Temperature Stability: Maintains mechanical strength and integrity in continuous operation at temperatures up to 1650°C in air.

• High Thermal Conductivity: Excellent heat transfer (196 W/m·K at room temperature) ensures maximum efficiency in heating or cooling applications.

• Outstanding Thermal Shock Resistance: Withstands rapid temperature changes (>350 ΔT), preventing cracking and failure.

• Excellent Wear & Erosion Resistance: The extreme hardness (2350 HV) provides a long service life in applications with abrasive slurries or particulates.

• Fully Dense & Impermeable: Near-zero open porosity prevents gas or fluid permeation, ensuring product purity and structural reliability.
