Electric heating radiant tube is heat transfer by radiation light waves/electric heat transfer in the heat pipe is available in a variety of media. The heating medium is air, radiant tube efficiency higher than that of electric heat pipe. The service life of the radiant tube is relatively lower than the stability of the electric heating tube. Radiant tube heating element, have high, medium and low temperature furnace with arbitrary selection and special atmosphere furnace with specifications. Outside the casing in a seamless high-temperature alloy tube and plate coil pipe, centrifugal cast pipe, special non-metallic carburizing casing resistance, etc. And according to the radiant tube heating element under the condition of all kinds of atmosphere and poor circulation, when using general resistance alloy not applicable cases.
