18、erconnected by lines (see Figures A.3 and A.4).A utility flow diagram (UFD) is a special type of process flow diagram. It is a schematic representation of the energy utility systems within a process plant, showing all lines and other graphic means required for the representation of transport, distri

Lines representing main flows or main
32、 piping shall be highlighted.The following line widths as specified in ISO 128 (all parts) shall be used:a) 1,0 mm (0,4 M) for main flow lines;b) 0,5 mm (0,2 M) for graphical symbols representing equipment and machinery, except valves and fittings and piping accessories, rectangular frames represent
33、ing unit operations, process equipment etc., subsidiary flow lines, and energy carrier lines and auxiliary system lines;c) 0,25 mm (0,1 M) for graphical symbols representing valves and fittings and piping accessories, symbols representing process measuring and control functions, control and data tra

36、flows coming from of continuous on other diagrams shall be identified with arrows see Figure 1.For reversible flows arrows according Figure 2 shall be used.Figure 1 Arrow for in- and outgoing flowFigure 2 Arrow for reversible flowIf a diagram consists of several sheets, it is recommended that lines
37、representing incoming and outgoing flows and piping shall be drawn in such a manner that these lines continue at the same level when the individual sheets are placed next to one another horizontally and are aligned vertically.When a connection line continues to another diagram the end should be mutu

The reference should consist of a designation (see Figure 3).Figure 3 Arrow for connection line continuing on another diagram (with reference)5.3.3.3 Arrows for indication of flow directionArrows are to be incorporated in the lines to indicate the direction of the flows within the f

Arrow heads for indication of flow can be found in ISO 14617-2.Figure 4 Examples of arrows for indication of flow direction5
