Industrial heating pipe

The invention provides an industrial heating pipe, and relates to the field of heating pipes. The industrial heating pipe comprises a shell, the inner side of the shell is fixedly connected with a material passing pipeline, the outer surface of the material passing pipeline is fixedly connected with a positioning frame, the side face of the positioning frame is fixedly connected with a heating plate, the surface of the positioning frame is slidably connected with an ejection column, the outer surface of the ejection column is sleeved with a reset spring, and the reset spring is fixedly connected with the ejection column. A first squeezing and pushing plate is slidably connected to the inner side of the shell and fixedly connected with the jacking column. According to the industrial heating pipe, an elliptical disc is driven to rotate by starting a tightening motor, so that a first sliding plate and a second sliding plate are extruded to be close to each other, corresponding jacking columns are pushed to extru
