The meaning of numbers in chemical engineering drawings
Thread Content
We have a newly installed unit, and by looking at the chemical process diagram, there is a line labeled 40---SG6005--2C3S2R. I’m not sure what this pipeline represents; could someone with expertise please explain it? Points will be given for an answer based on the diagram
40---SG6005--2C3S2R: 40 is the nominal diameter of the pipe; SG is the code for the material; 6005 is the main product code; 2C3 indicates the material and pressure rating of the pipe; S2R denotes the material and pressure rating of the heat tracing tube
Go and check the pipeline grade table instructions for the materials engineering field
The PID chart comes with a legend; refer to the legend to understand it. The legends among different design institutes are not exactly the same.
