Sintered SiC Heat Exchanger Tubes
Hexoloy® SE silicon carbide heat exchanger tubes provide the most reliable choice for high-temperature, high-pressure chemical processing applications.
Upgrade your shell or tube heat exchanger system to the industry’s most high-performance, efficient tubing option — Saint-Gobain’s Hexoloy® SE sintered silicon carbide (SiC) heat exchanger tubes. Hexoloy SE tubes feature unmatched reliability, strength, high thermal conductivity, ultra-high purity and virtually universal corrosion resistance. Saint-Gobain is the only source for sintered SiC heat exchanger tubing, with more than 25 years of experience in the chemical industry.
Too often, heat exchanger tubes made from other materials such as graphite and glass have to be replaced due to fouling or breakage. Lower your manufacturing costs, increase your operating efficiency and maximize profits by insisting on heat exchanger systems made with Hexoloy® SE tubes, which are non-fouling and strong with ultra-long life even in the harshest conditions.
Benefits of Hexoloy® SE Sintered Silicon Carbide include:
Non-fouling- High strength
- Ultra-long life
- Excellent thermal conductivity
- Universal corrosion resistance
- Extreme hardness and wear resistance
- Lowers operating and maintenance costs over the life of the product
- Improves efficiency by reducing down time and maintenance
- Meets tough chemical industry standards worldwide
Hexoloy® SE heat exchanger tubes are available in outer diameters of 0.75" (19mm), 0.55" (14mm) and 0.50" (12.7mm) at lengths up to 15 feet (4.6m).
