Description

Technical Field

[0001] This utility model relates to the field of furnace tube technology, and in particular to an explosion-proof furnace tube. Background Technology

[0002] Furnace tubes are the core components of industrial heating equipment. They are mainly used to carry high-temperature media and realize heat transfer. They are widely used in chemical, metallurgical, and energy industries. Their working environment is often accompanied by high temperature, high pressure and corrosive media, so they have high performance requirements. The thermal stress generated during the heating and cooling process of existing furnace tubes cannot be effectively released. At the same time, corrosive media can easily cause local erosion of the inner wall of the furnace tubes. Furthermore, there is a lack of real-time monitoring and buffering mechanisms for furnace tube deformation, which means that the furnace tubes still have the risk of bursting during long-term use, seriously affecting production safety and equipment lifespan.
