Silicon carbide pipes 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.
SiC thermal couple protection tube is oxidation resistance, high thermal conductivity, corrosion resistance, low coefficient of thermal expansion. They can be used in metallurgy industry, chemical industry and ceramics industry. They can be used as temperature-checking protection tubes.
Silicon carbide tubes are mainly used in medium frequency forging, various heat treatment electric furnaces, metallurgy, chemical industry, non-ferrous metal smelting and other industries. Widely used in metallurgical sintering furnace and intermediate frequency heating forging furnace. Length can be designed.
