Ask for help: Thank you so much! ! ! Type FR700-130-16-2 FB600-85-40-4 YB500-55-25/25-4 FLB800-170-25-2 What type of heat exchanger does the above indicate? What standard contains specific instructions for this type?
This part of the content can be found in GB151 On page 11, there is a method of expressing the heat exchanger model according to the standard writing. Take the first one as an example FR (the mother of English should be in the form of front-end pipe box, shell, and rear-end pipe box respectively, but I can’t match the model here in the standard, so I can only find an expert to explain) 700 Engineering diameter, the coiled plate is the inner diameter, and if the steel pipe is used, it is the outer diameter - (there is a design pressure between these two parameters, which is omitted here) - 130 heat exchange area - 16 nominal length of the heat exchange tube - 2 number of tube passes, the shell side is omitted, please check the standards for details. If you want to download the standards, you can go to the Standard Sharing Network ( www.bzfxw.com ).
