While looking at the flowchart today, I don’t understand what these pipe grades such as 42AE2 and 42SJ1 mean ? Does anyone know? It’s a SEI diagram, but I can’t understand it

1. Look at the home page of the flowchart; there should be instructions there； 2. Check the pipeline grade table for the project.

This is SEI’s pipeline grade code; I wonder if anyone has information on this?

If you obtained the PID through normal channels, then you can definitely ask SEI for the relevant items, right?
