Outer protection sleeve is thin-walled cold-drawn seamless steel tube, the material is Fe-Ni-Cr-Al-Re alloy, the material has a high antioxidant capacity, 1300 degrees inoxidizing atmosphere can work long-term, short-term antioxidant 1360. Suitable forhigh temperature and low oxygen partial pressure environment and s, c. Our company design and manufacture of Electric Radiant tubes, high, medium and low temperature furnace and special atmosphere furnace specification of arbitrary choice. Outer casing with welded tubes and coils of high temperature alloy tubes, special anti-carburizing for centrifugal ductile iron pipes, non-metallic casing. And according to theradiant tube heating elements in the atmosphere and bad circulation when used under the conditions, resistance alloys will not generally an appropriate case. Companyresearchers have developed a new kind of radiation resistance alloy pipe material.This material is stable, high resistivity and temperature coefficient is small, adapt to a variety of radiant tube heating elements used in special use properties instead of the expensive imported materials.
