Abstract: Described in the article are the main aspects of heat treatment of the seamless steel tube，including the purpose，the common-used processes and schemes，the process flow，methods for layout determination as well as the general principle for equipment type selection，etc. Analyzed are the work principles，advantages and disadvantages，and application scopes of different pipe heat treatment facilities，offering references for investors and professionals engaged in such field. The layout and equipment type selection of the steel pipe heat treatment line should be determined according to the product mix. Based on the actual production conditions，the pipe maker should further optimize the design plan so as to get the best process scheme and process equipment configuration of the pipe heat treatment line.
