Regarding the selection of equipment flanges
Thread Content
Under what circumstances are non-standard equipment flanges used for fixed-tube-sheet heat exchangers? If a non-standard option is chosen, does it mean that the equipment flanges need to be calculated in SW6? Is a non-standard version simply one whose flange dimensions and thickness differ from those specified in the standard?
Fixed-tube sheet heat exchangers use non-standard equipment flanges, usually because it is necessary to meet certain special engineering requirements or design needs. For example, flanges made of high-strength materials may be required to meet the demands of high-pressure or high-temperature conditions, or flanges of certain special shapes or sizes may be needed to fit the equipment’s structure or installation method. If non-standard equipment flanges are used, it is necessary to perform calculations on these flanges in SW6 to ensure that they meet the design requirements and can be used safely and reliably. The flanges of custom equipment usually only follow the external dimensions and shape of those specified in standards, but they may differ from the standard ones in terms of material, structure, and performance; therefore, calculations are necessary to ensure that they meet the design requirements. .
