How to draw a flowchart
Thread Content
I’ve been drawing flowcharts recently and am not sure how to represent various devices in them (such as filters, mass flow meters, raw material mixers, etc.). I hope the experts here can give me some advice!
There’s a legend at the beginning of the flowchart, or it’s also available in the drawing software
Download HG 20559 from the Internet; this is the standard for process PID flow diagrams
Take a look at HG’s specifications; there are typical legends
First of all, once you start working at a design firm, experienced designers will surely guide you in drawing. Design firms have their own standard requirements for drawing and legends; the simplest way to get started is to look at the flowchart drawings from previous projects. They all have graphic symbol codes. Second, one can start by learning the relevant ** and industry standards for drawing process flow diagrams. Relevant standard specifications include \"GBT 6567-2008 Technical Drawing – Graphic Symbols for Piping Systems\", \"HGT 21581-2010 Manual for Automatic Control Installation (Volume 1)\", \"SH3122-2000T Specifications for the Design of Process Piping in Refining Plants\", \"SH3101-2000 Legend for Process Diagrams in Refineries\", and so on.
I have the same question; thank you all for your answers.
