Technical Field

[0001] The utility model belongs to the technical field of tubular heating furnaces, in particular to a tubular heating furnace tube hanger. Background Art

[0002] Tubular heating furnace is a process heating furnace used in industries such as petroleum refining, petrochemicals, coal chemical industry, tar processing, and crude oil transportation. The heated material flows in the tube in the form of gas or liquid, which are both flammable and explosive substances. The operating conditions are harsh, and the furnace must operate continuously for a long period of time. The heating method is direct exposure to fire.

[0003] When using a tubular heating furnace, the furnace tube needs to be supported by a hanger. When installing the furnace tube, the staff needs to adjust the height of the tube according to the actual situation, so that the adjacent tubes can be accurately docked and installed. However, due to the different lengths of the furnace tubes, the existing hanger is difficult to control and adjust the length of the furnace tubes, which causes the furnace tube to shake during use, thereby affecting the normal operation of the subsequent heating furnace.
