Core Characteristics of Silicon Carbide Tubes for Shell and Tube Heat Exchangers

Silicon carbide tubes (SiC tubes) for shell and tube heat exchangers have a set of core characteristics that make them ideal for high temperature, high pressure and corrosive environments. The following is a detailed summary of the core characteristics of silicon carbide tubes:

High Strength & Hardness of Silicon Carbide Tubes

The hardness of silicon carbide tubes is very high, usually between 9-9.5 Mohs hardness, which is close to the hardness of diamond. This high hardness characteristic enables the silicon carbide tube to withstand extremely high mechanical stress and is not prone to deformation or rupture. At the same time, its high strength characteristics also ensure the stable operation of the shell and tube heat exchanger under high pressure working environment.

Excellent Wear Resistance of SiC Tubes

Due to the extremely high hardness of the silicon carbide tube, its wear resistance is also very good. In shell and tube heat exchangers, silicon carbide tubes can withstand fluid erosion and particle wear for long periods of time without significantly reducing their service life.

High Temperature Resistance of Silicon Carbide Tubes

Silicon carbide tube has excellent high temperature resistance and can be used stably in high temperature environment for a long time. Its use temperature can generally reach more than 1600 ° C, and even some special types of silicon carbide tubes can withstand extreme working environments of up to 2400 ° C or more. This makes silicon carbide tubes an ideal material for high temperature heat exchangers.

Corrosion Resistance Properties of SiC Tubes

Silicon carbide tube has good corrosion resistance, can withstand a variety of acid, alkali, salt and other chemical media erosion. In corrosive environments such as strong acids and alkalis, the surface of silicon carbide tubes usually forms a dense oxide film to protect them. This characteristic makes the silicon carbide tube perform well in the process of handling corrosive media.

Antioxidant Performance & Thermal Conductivity of SiC Tubes

When the silicon carbide material is heated to a certain temperature in the air, its surface will begin to form a protective layer of silicon dioxide. With the thickening of the protective layer, the continuous oxidation of the internal silicon carbide is prevented, so that the silicon carbide has better oxidation resistance. This characteristic helps to extend the service life of the silicon carbide tube and keep its performance stable.

Silicon carbide tubes have a high thermal conductivity, generally between 120-150 W/(m·K). This allows the silicon carbide tube to conduct heat quickly and is suitable for heat transfer applications in high temperature environments. In shell and tube heat exchangers, this characteristic of silicon carbide tubes helps to improve heat exchange efficiency and reduce energy consumption.

The thermal expansion coefficient of silicon carbide tube is low, generally between 4.0-5.0×10^(-6)/K. This allows the silicon carbide tube to maintain good dimensional stability under high temperature conditions, and is not easy to crack or deformation due to thermal expansion. This feature helps ensure long-term stable operation of the shell-and-tube heat exchanger.

Dimensional Stability & Customization Options of SiC Tubes

Silicon carbide tube can be processed and customized according to actual needs, including length, diameter, wall thickness and other parameters adjustment. This allows the silicon carbide tube to flexibly adapt to the design requirements of various shell and tube heat exchangers and meet the needs of use under different working conditions.
