Could someone tell me what the meaning of this pipeline number is: 2-23017-150CB83-28.0-ABb-H70. This post was last edited by Zhang Yongliang on 2008-1-12 at 08:50.]
Take a look at the legend for the PID in the process engineering section. Anyway, the final H70 is the insulation thickness
A general pipe code includes information such as the material code, simplified code for the main category, pipe sequence number, nominal diameter, and pipe grade; the pipe grade contains details such as the pressure rating and pipe material. The original poster can check it against. Of course, if there are insulation pipes, as mentioned above, that information should also be included.
According to HG20519, the marking of pipes generally consists of 6 units. For example, the pipe designation PG1310-300 A1B-H means: Unit 1 – material code 13; Unit 2 – main item number 10; Unit 3 – pipe sequence number 300; Unit 4 – pipe size A1B; Unit 5 – pipe grade: A denotes nominal pressure 1, while B refers to the pipe material, which is H. Unit 6 – insulation or soundproofing code. Similarly, 2-31017 likely represents the information from the first three units; 150 indicates the pipe size, ABb denotes the pipe grade, H70 is the insulation code. The remaining value of 28.0 is probably the pressure grade, and CB83 might be the material code, though this is just a guess. If the design drawings can be found, the legend should contain detailed explanations.
It must be the project’s own numbering system used by foreigners; it’s best to get the homepage image or instructions, otherwise it’s completely incomprehensible.
That’s right; the uniform regulations vary for each item
The first one should be a pipe with a diameter of 2 inches; 23017 is likely the pipeline identifier
Generally, there will be instructions on the PID homepage; it’s best to read them before discussing!
Who can tell me what pipe grade 150C2 means? Thank you!
150 likely indicates a design pressure of 150 pounds; C is the material code, and 2 is the sequence number. For such issues, one can only refer to the project’s design documents, such as the construction design specifications and the regulations regarding pipe grades. Different design firms use various numbering methods.
Find the legend for that drawing of yours, and the problem will be solved easily.
