Silicon carbide pipes (riser sleeve , silicon carbide tube, ceramic tube , sanitary ware kiln part , silicon carbide heating element )are also known as silicon ceramic pipes, which belong to the refractory pipe family .it is crystallized from silicon nitride and silicon carbide,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.
