GORGEOUS CERAMICS (GGS) silicon carbide heat exchange tubes are made from spray-granulated silicon carbide powder, extruded, and sintered at high temperatures.
We can customize tubes according to your drawings, performing precision machining on the outer diameter and end faces as required to meet your application needs. We can also monitor the tube’s outer diameter, wall uniformity, surface smoothness, roundness, and straightness online using a laser diameter gauge.
Performance Advantages of Silicon Carbide Heat Exchange Tubes
Our products possess comprehensive chemical corrosion resistance, resisting mixed acid corrosion such as hydrofluoric acid, ensuring a longer service life;
They exhibit excellent thermal conductivity, with silicon carbide material boasting a thermal conductivity exceeding 140 W/m·K, enabling rapid heat exchange;
Passing water pressure testing standards, each of our silicon carbide tubes undergoes testing at 100 Bar (60 seconds), ensuring reliability and safety;
Passing straightness standards, our products maintain a straightness (unit: mm/m) ≤ 1.2%. Every heat exchange tube must pass standard tube inspection before leaving the factory;
Silicon carbide heat exchangers offer outstanding heat exchange efficiency, are more compact and smaller in size compared to traditional heat exchange equipment, and save 70% of installation space compared to glass-lined heat exchangers (requiring a smaller heat exchange area for the same heat transfer). Because they are easy to disassemble, silicon carbide heat exchange tubes can be directly accessed for cleaning or inspection, resulting in low maintenance costs.

Typical Applications of Silicon Carbide Heat Exchanger Tubes
Silicon carbide heat exchanger tubes are the core component of shell-and-tube heat exchangers. They are suitable for various chemical processes such as cooling, condensation, heating, evaporation, thin-film evaporation, and absorption of chemicals. They are particularly suitable for highly corrosive chemicals such as bromine, sulfuric acid, hydrofluoric acid, nitric acid, hydrochloric acid, sodium hydroxide, or other strong halogenated compounds.
