SiC Heat Exchanger Tubes

Semicorex SiC heat exchanger tubes are typically installed inside a shell-and-tube heat exchanger, with multiple such tubes constituting the shell-and-tube heat exchanger. Thanks to the excellent thermal conductivity of silicon carbide ceramics, the shell-and-tube heat exchanger realizes efficient heat transfer between fluids (such as water, air and process gas) of varying temperatures flowing inside and outside tubes.

Advantages of Semicorex SiC heat exchanger tubes

Semicorex SiC heat exchanger tubes are made of high-quality spray-granulated SiC powder via extrusion forming and high-temperature sintering, delivering outstanding overall performance detailed below.

1.Precise quality control

By using laser diameter gauges, Semicorex precisely controls the outer diameter, wall uniformity, surface smoothness, roundness, and straightness of SiC heat exchanger tubes, making them fully in compliance with inspection standards. Also, each our SiC heat exchanger tubes will undergo strict pressure testing to secure their reliability and safety in operation.

2.High-efficient thermal conductivity

Semicorex SiC heat exchanger tubes have excellent thermal conductivity and their material's thermal conductivity exceeds 140 W/m·K. They offer remarkable heat exchange efficiency, which minimizes both required heat exchange area and overall space occupation of the shell-and tube heat exchanger.

3.Stable thermal and chemical stability  

Benefiting from their reliable thermal and chemical stability, Semicorex SiC heat exchanger tubes can resist corrosion by strong acid, alkaline fluids, and gases under high-temperature operating conditions, especially such as hydrofluoric acid, which effectively avoids undesired impurity contaminant release in high-purity production processes.

Applications of Semicorex SiC heat exchanger tubes

With the above superior performance, Semicorex SiC heat exchanger tubes are ideal solutions for conditions with high temperature, high pressure, severe chemical corrosion, gas erosion, and particle wear and are well-suited to cooling, heating, condensation, evaporation, thin-film evaporation, and absorption in chemical production.
