Regarding the issue of pipeline numbering at Tianjin Tianchen Design Institute
Thread Content
What does AS1301—8‘—S22b—H80—C24 specifically mean? I would be greatly grateful if fellow sailors could explain the meaning of each code
In AS1301—8’—S22b—H80—C24, AS is the material code, 1301 is the pipeline serial number, 8” is the pipe diameter (in imperial units), H80 refers to the insulation thickness, and C24 denotes the pipeline grade. As for S22b, I’m not entirely sure either; these are just my personal opinions
The legend should indicate the meaning of each unit
The answer is upstairs; the legend on the first page of Tianchen’s drawings provides a very detailed explanation
S22B should be a pipe grade!
2# missby: In the answer on the second floor, S22B should refer to the pipe grade, while C24 is the designation for pressure pipes.
LS is the correct answer, or it is specified in the relevant process standards!
