Product Description retort muffleMuffle tank consists of burner and muffle tube. One end of muffle tube is connected with the burner and runs through the furnace, the other end is connected with the flue. The combustion flame flows from muffle tube to the flue and radiates heat to the furnace through the pipe wall. Because the way of heat transfer is mainly radiation, it is called radiation tube. It is mainly composed of radiation tube body, burner, air preheater and hot air channel. At present, in addition to gas radiant tubes, there are also electric heating radiant tubes, that is, the resistance wire transfers heat to the heat treated workpiece in the form of thermal radiation on the surface of the heated sleeve through electric heating in the pipe.The main products of Qingdao Hexin Machinery Co., Ltd. include: U radiant tubes, W radiant tubes, Straight radiant tubes, Electricity radiant tubes, Special radiant tubes. Ethylene cracking furnace, furnace tube, reformer furnace tube, and so on.Qingdao Hexin Machinery Co., Ltd. offer custom engineering and production: Bung assemblies,flanges,reducers, return bends, centrifugal cast tubes, and tube hangers, assembled or individual parts.With many years experience, the electricity heated radiant tube we manufactured are approved by customers from europe and the USA. Closed the electric heating element in outer sleeve ,the outer sleeve is kind of high temperature alloy centrifugal casting tube, Internal heat to electrical heating core, After the electrical heating, radiate the heat to furnace lining and heated workpiece indirectly through outer sleeve, this radiant tubes are usually used for continuous furnace, roller furnace and pit furnace of continuous annealing line and galvanizing line. Commonly used material for 1.4848,2.4879,etc,the regular size is OD203mm,OD216mm.
