31、l position corresponding to their functions.5.3 Connecting lines5.3.1 Line widthsLine widths shall be related to the grid module (in accordance with ISO 81714-1) for flow diagrams, M = 2,5 mm.To obtain a clear representation, different line widths shall be used. 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

34、nsmission lines, reference lines, and other auxiliary lines.Line widths less than 0,25 mm (0,1 M) shall not be used.5.3.2 Minimum space of parallel linesThe minimum space between parallel lines shall be at least twice the width of the widest line, but at least equal to 1 mm. Space between flow lines

35、 should be greater than 10 mm.5.3.3 Flow direction5.3.3.1 GeneralNormally, the main flow direction shall be drawn from left to right and from top to bottom.8DIN EN ISO 10628-1:2015-04 EN ISO 10628-1:2015 (E) 5.3.3.2 Arrows for diagrams in- and outgoing flowsIn- and outgoing flows of a diagram, also

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

38、ally referenced. 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

39、low diagram. In order to facilitate understanding, arrows can be used at the inlets to equipment and machinery (except for pumps) and upstream of pipe branches (see Figure 4). Arrow heads for indication of flow can be found in ISO 14617-2.Figure 4 Examples of arrows for indication of flow direction5
