The invention belongs to the technical field of new energy, efficient energy saving and energy saving of high-energy-consuming industries such as a power industry and particularly relates to a copper-chromium-based TGr-titanium film thread pipe type air preheater and a pipe film component. According to the copper-chromium-based TGr-titanium film thread pipe type air preheater and the pipe film component, a base pipe and a copper-chromium-based TGr-titanium film layer are included. The copper-chromium-based TGr-titanium film layer is arranged on the outer side of the base pipe. The copper-chromium-based TGr-titanium film thread pipe type air preheater and the pipe film component have the advantages that the heating area can be increased through threads, so that air side heat transferring capacity is greatly improved, meanwhile, flue gas flow speed is reasonably selected, under ripple disturbance, ash deposition phenomena hardly exist, heat transferring capacity is improved, so that wall temperature is improved, low-temperature corrosion is lowered, flue gas side heat is well used, the burning state is improved, and efficiency is improved.
