GB/T28712.2-2012 for fixed-tube-sheet heat exchangers specifies two sizes for the heat exchange tubes (diameters of 19 and 25 mm), with the minimum length of such tubes being 1500 mm. According to GB/T151-2014, there are various sizes available for heat exchange tubes, the minimum length being 1000 mm. Can fixed-tube-sheet heat exchangers use heat exchange tubes with a minimum length of 1000 mm along with other sizes?

It depends on the design and calculations; if there are constraints related to the equipment and the space available, then the value has to be less than 1000 mm – practicality needs to be taken into account in various aspects
