Pipe insulation type
Thread Content
I have a question: on the pipeline drawings, the insulation type is indicated as NI (F2). What does this mean? Does anyone know?
Look at the legend on the first few pages of the flowchart; there is no universal standard, so you can only rely on the legend
It is estimated that N1 or F2 correspond to different parameters such as insulation thickness; the specifics depend on the legend or annotation requirements
No, I’m not quite sure what this is. It’s recommended to take a look at the sample and see if the instructions on it indicate this meaning
