What is silicon carbide tube？
Silicon carbide tubes are high-performance, dense ceramic products widely used in industries that require high temperatures. Gotrays SiC tubes are known for exceptional temperature resistance and long service life. They are primarily utilized for heating, cooling, gas transportation, and as structural supports in kilns. Gotrays is a leading silicon carbide tube manufacturer in China, offering a diverse range of products and kiln solutions.
Silicon carbide tubes are cylindrical-shaped ceramic tubes made from silicon carbide (SiC). SiC is an alloy composed of silicon and carbon that offers superior mechanical properties, high temperature resistance and excellent chemical resistance. Silicon carbide tubes are frequently employed in industries like ceramics, metallurgy, and high-temperature applications where thermal stability and chemical resistance are essential. Their robust design provides an environment where multiple processes can take place safely at extreme temperatures. These tubes feature high thermal stability and can withstand temperatures up to 1600degC (2912degF). Furthermore, their low thermal expansion coefficient means they resist cracking or warping under rapid temperature changes. Silicon carbide tubes boast exceptional chemical resistance, making them suitable for applications involving corrosive materials or environments. Their strength allows them to withstand acids, alkalis and other common industrial processes used to produce them.
