Why does a pipe have two different designations for its pipe number? Who can tell me what materials are used in these two designations? Thank you!
Are B15ED3 and 2A5B made of the same material? What do each letter and digit represent? Thank you
There is a legend accompanying the drawings; check the legend
According to common understanding, B1 should be the pressure rating code, while 5E should be the material code; the specifics depend on the legend
The specifications of the heat tracing or cooling pipes may be indicated in the circles on the physical diagram
It is possible that the 2 design subcontracts are coded separately.
This is probably the pipeline grade code from the design firm; it’s necessary to consult the original designer
Check the pipe material properties table in the design documents
Just use the pipeline grade table from the design institute and compare it; it’s very easy. Many times, mistakes occur, and serious mistakes at that, without a pipeline grade table from a design institute ! !
