ASME Y 3 2 . It is suggested that the equipment outlines be drawn by heavy lines. 3. The main idea i s to preserve the general physical appearance of the equipment. Thesymbolsshouldbe arranged on the drawing in logical sequence of flow. A process flow diagram is thefirst drawing made to show the basic items of major equipment and their relation to one another in the process scheme. with the minimum strokes to a draftsman. SCOPE This preliminary s e t of standard symbols h a s been developed for use on the basic process flow diagrams in order to represent the major items of equipment used by the petroleum and chemical industries. with a minimum of cross-over lines. 5 COPYRIGHT 2002. buttherelativesize of the symbols shouldbe selected in keeping with the overall size of the completed drawing.
