20、cess plant by means of graphical symbols which are interconnected 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 mean
21、s required for the representation of transport, distribution, and collection of forms of energy. In a utility flow diagram, process equipment can be represented by boxes with inscriptions and with utility connections (see Figure A.5).The graphical symbols represent equipment and the lines represent

30、fting rules5.1 General5.1.1 Sheet sizesA1 size as defined in ISO 5457 should preferably be used for drawing sheets. Considering the various copying techniques (reduction) available, long sizes and sizes larger than A1 are to be avoided.5.1.2 Title blockThe basic title block for drawings and lists (w
31、ith additional fields) as shown in ISO 7200 shall be used.4 ISO 2014 All rights reservedBS EN ISO 10628-1:2015ISO 10628-1:2014(E)5.2 Layout of flow diagramsGraphical symbols for equipment and machinery could be enlarged in order to give a clear representation of internals and connections.Devices to
32、be expected at the uppermost level of the plant shall be shown at the top of the drawing and those expected to be located at the lowest level shall be shown at the bottom of the drawing.The graphical symbols for process-related measuring and control functions for equipment, machinery, and piping, as
33、 well as those representing piping and valves, shall be shown in the logical 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,
34、 different line widths shall be used. Lines representing main flows or main 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, exce
35、pt valves and fittings and piping accessories, rectangular frames representing 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
36、 representing process measuring and control functions, control and data transmission 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 wid
37、th of the widest line, but at least equal to 1 mm. Space between flow lines 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.

38、(E)5.3.3.2 Arrows for diagrams in- and outgoing flowsIn- and outgoing flows of a diagram, also 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
39、Arrow for reversible flowIf a diagram consists of several sheets, it is recommended that lines 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 ar
40、e aligned vertically.When a connection line continues to another diagram the end should be mutually 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 directio
41、nArrows are to be incorporated in the lines to indicate the direction of the flows within the flow 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
42、 flow can be found in ISO 14617-2.Figure 4 Examples of arrows for indication of flow direction5.3.4 ConnectionsWhen pipes are represented by the same line width cross, but are not connected to each other, the line depicting the vertical pipe shall be interrupted see Figure 5a).6 ISO 2014 All rights

46、ertical lettering in accordance with ISO 3098-2 is recommended.Legends and designations in flow diagrams shall always be written in upper-case characters. The only exceptions to this rule are chemical formulae (e.g. NaCl), abbreviations referring to technical regulations and legislation (e.g. BImSch
47、G), and other cases where there is a danger of confusion if only upper case characters are used.5.4.2 Height of letteringThe height of letters shall be:a) 5 mm for designations of equipment and machinery;b) 2,5 mm for other lettering.5.4.3 Lettering arrangementa) Plant equipment ISO 2014 All rights
