Silicon carbide pipes are also known as silicon ceramic pipes, which belong to the refractory pipe family. This kind of pipe is made of clay bonded silicon carbide material, which has good wear resistance, heat resistance, corrosion resistance and high temperature performance. Silicon carbide pipe is the ideal lining material of smelting steel industry, because it has the advantages of high temperature resistance, good slag erosion resistance, high strength and long service life.
