It should be the pressure level. The pressure level expression specified by each design institute is different. You should look for the home page of your drawing, which has an introduction.
Brother, is this a universal description? I don’t think so. It should be the standard writing method of an engineering company or a certain owner. If so, you should check the legend of PID. Who should I ask here, unless I happen to have encountered it?
150 is the pipe diameter, P is the main process medium, 33080 is the pipeline number, I don’t know what N2B2 means.
Guess 150 is the pipe diameter, P is the main process medium, 33080 is the pipeline number, N is no insulation, 2B2 is the pipeline grade
150 is the nominal diameter of the pipeline, P is the process medium code, 33080 is the pipeline number, and N2B2 is the pipeline grade code (N represents the pressure level of 2.5MPa, B represents the material is carbon steel, and the remaining numbers are sequence numbers)
Thank you:):):) Support:):):) It is probably done by the design institute.
