A Brief Introduction for Centrifugal Cast Radiant Tubes
Hello everyone, what I want to introduce to you today is one of the main products produced by our factory, Centrifugal Casting Radiant Tube.
Radiant tubes are commonly used as heating parts in heat treatment furnaces. 
They are installed inside industrial furnaces and play an important role in the operation of industrial furnaces.
Many  visitors may not know much about radiant tubes. 
Today, I will tell you about the components of radiant tubes.
Radiant tubes generally include, centrifugally cast pipe sections, precision cast elbows, flanges that can be filled with refractory fibers and welded protective plates, and burners.
Commonly used centrifugal casting radiant tube, the wall thickness of the tube is generally between 6-12mm, the outer diameter of the radiant tube is 80-219mm, 
and the shape of the radiant tube is different depending on the type of heat treatment furnace, including W type radiant tube, U radiant tube, and I radiant tube. tube, P radiant tube, etc.
The radiant tube has the following outstanding advantages: high thermal efficiency, rapid temperature rise, small thermal lag, good heat transfer performance, 
which can ensure the controllability of the atmosphere in the heat treatment furnace, and the installation, inspection and maintenance are all carried out outside the furnace without stopping the furnace. 
Or cool down the furnace temperature to repair and replace the electric heating device.
At present, the radiant tubes produced by Qingdao Hexin Machinery Co., Ltd. are basically heat-resistant steel, using centrifugal casting process and welding process.
Qingdao Hexin Machinery Co., Ltd. has many years of experience in the production of radiant tubes, from the selection of raw materials,
 centrifugal casting process, welding assembly, break processing, pressure testing, and various non-destructive testing, such as PT, RT, to ensure the reliable quality of radiant tubes.
Commonly used materials are austenitic heat-resistant stainless steel, such as ASTM A351 HK40, 1.4848, 1.4852, 2.4879, etc.
HEXIN can customize different radiant tubes according to customer requirements, according to drawings, specifications, materials, etc.
