1 AGRAPHICAL SYMBOLSFOR PIPING SYSTEMSAND PLANTBASED ON BS 1553: PART 1: 1977 ScopeThis part of BS 1553 specifies GRAPHICAL SYMBOLS for use in flow and PIPING diagramsfor process 1 SYMBOLS (or elements of SYMBOLS ) for Use in Conjunction withOther SymbolsMechanical linkageWeight deviceElectrical deviceVibratory or loadingdevice (any type)Spray deviceRotary movementStirring deviceFanAccess pointEquipment penetration(fixed)Boundary linePoint of changeDischarge to atmosphereEquipment branch:general symbolNote. The upper repre-sentation does notnecessarily imply aflange, merely the ter-mination point. Where abreakable connection isrequired the branch/pipewould be as shown in thelower symbolEquipment penetration(removable)APPENDIX A GRAPHICAL SYMBOLS FOR PIPING SYSTEMS AND PLANTA-2 Basic and Developed SYMBOLS for PLANT and EquipmentHeat Transfer EquipmentHeat exchanger (basic SYMBOLS )Alternative:Shell and tube: fixed tube sheetShell and tube: U tube or floating headShell and tube.
