Dear sea friends, please explain to me what 3\"F152F/B-304/316-3-P-FS-VN(U.1/8) and 6\"R152F/EG-CD3MN/CD3MN-3-P mean. Thank you!
Isn’t it explained in the drawing notes?
Reply to 2# 383770393: There isn’t any, especially the -3-P at the end – I don’t know what that means
I only know that the first one is a waste pipe with a size of three inches (DN75), and 304/316 indicates the material. The second one is a 6-inch (DN150) hot water pipe; I’m not sure about the others, waiting for an expert to explain
Reply to 4# hs437225: I’m sorry, it’s completely wrong; I’m also waiting for an expert to explain it
A pipe number usually consists of 5 parts: 1. Material code; 2. Pipe identifier: the number of the engineering process (main item) to which the pipe belongs, along with the sequence number of the pipe; 3. Pipe size, expressed in imperial units using a comma, e.g., 3. 4. Fourth part: Pipeline grades. 5. Insulation, fire protection, and sound insulation symbols. I analyze that P is usually used for personal protection (typically above 60 degrees, with insulation material to prevent burns). This pipeline number is quite rare; it belongs to which foreign company? This information should be indicated on the homepage diagram of PID.
:dizzy: Come on, does everyone really think it’s a pipe?
