Radiant Tube

what is a radiant tube A radiation tube is a tube extending straight from the center in all directions.It refers to a non-central pipe (or dry pipe) which conveys the material action of the dry pipe to a designated or non-designated address.Radiation tube is widely used in heating furnace and is the main heating element of heating furnace. Application of alloy The radiant tubes are working at high temperature environment on average: 800-120 C, most of them are used for indirect heating to furnace like CAL (continuous annealing line) CGL (continuous galvanizing line). Process of alloy Centrifugal/spun casting method for tube sections, investment casting or sand casting for the bends, hangers, welding and machining Material of alloy High Nickel and high Chrome heat resistant alloys, Cobalt base alloys, like.

silicon carbide radiant tube Product performance of silicon carbide radiant tube Silicon carbide radiant tube this product has the characteristics of good thermal conductivity, high temperature resistance, corrosion resistance, oxidation resistance and long service life. Application of silicon carbide radiant tube Silicon carbide radiant tubes are widely used in gas and oil industrial kilns such as tunnel kilns, shuttle kilns and roller kilns, as well as industrial coke ovens in iron and steel metallurgy and other industries. 1. The inner tube of the flame is made of silicon carbide, and SiSIC can withstand high thermal stress; 2. Multiple sections of inner tubes can be combined into inner tubes of required length according to the length of radiant tubes; 3. The SiSIC flame inner tube allows the metal radiation tube to bend without damaging the flame inner tube and radiation tube; 4. Compared with the metal tube, the load of SiSIC in the radiation tube can be reduced; 5. Compared with metal inner tube, SiSIC flame inner tube has higher thermal conductivity. Specification of silicon carbide radiant tube The specific specifications of silicon carbide radiant tube can be made according to the needs of users
