Shell & Tube Heat Exchangers
Sintered Silicon Carbide Tubes and Tube-sheets
For more than 30 years, Hexoloy® SE silicon carbide tubes have provided the most reliable and preferred choice for shell & tube heat exchangers used in fine and specialty chemicals. This success is based on virtually universal corrosion resistance, high thermal conductivity, extremely high hardness and mechanical strength of Hexoloy®.
Hexoloy® SE tubes are available in 12.7 mm, 14 mm, and 19 mm outside diameter and lengths up to 5 m. Each tube is proof tested up to 186 bars (2700 psi). Hexoloy® SA SiC tube sheets are also available as per OEM design.
Saint Gobain Ceramics has sold more than one million meter of heat exchanger tubes.

*Test Time: 125 to 300 hours of submersive testing, continuously stirred.
Does Saint Gobain design and build heat exchangers?
No. Saint Gobain works with heat exchanger OEMs worldwide.
How do Silicon Carbide tubes perform against fouling liquids?
Silicon Carbide tubes are known to offer greater resistance to fouling.
What are the key benefits of using Silicon Carbide Tubes?
Hexoloy® Silicon carbide is essentially inert to a wide range of corrosive chemicals, including strong acids and caustics, up to 200°C. Most alternatives, such as graphite, metals, alloys, introduce contamination over time from corrosion. Other key benefits include high heat transfer, superior mechanical strength, and low thermal expansion.
