I’ve been learning pipeline single-line diagrams recently, and the English version seems quite difficult. Could anyone who knows a lot about this topic provide a summary of the relevant knowledge points? Thank you all here.

They’re all simple. If there’s anything you don’t understand, let me give an example: Item number 3 is a half-elbow with a diameter of 150, made of 20-grade steel, welded by socket welding, SW type, with a pressure rating of Class 3000; the standard code for this is 14383, Series II. Item number 4 is a 90-degree long-radius elbow with a diameter of 150, also made of 20-grade steel, seamless, with a wall thickness of 6 mm. One set of standards relates to dimensions, while the other relates to manufacturing methods. What else isn’t known? These are all basic skills, the most fundamental things.
Isn’t it much simpler to express things in English than in Chinese?
This should be a drawing created in CADworx
He used a single-line diagram exported from PDS and added some Chinese text; if you’re used to it, there’s no need to make any changes
