How do I read a piping diagram for chemical process engineering?
You mean the piping diagram in CAD format, right? In fact, just like the process flow diagram, it is a sectional view; usually one diagram is provided for each floor. It is important to pay attention to the elevations and the direction of pipe bends, as well as the connections to the equipment outlets. It’s best to examine it in conjunction with the actual equipment on site! That makes it easier to understand
First, get to know the various legends; read HG/T 20519-2009 once.
Any more suggestions? My QQ is 397945021

One pipeline corresponds to one piping diagram: identify the starting point of the piping diagram and match it with the actual installation location, then determine the length of the pipeline ahead and its angle; going forward step by step for each fitting, it looks very clear
