Who knows what the markings on DOT-4BW cylinders mean? It can’t be found online either.

First of all, thank you to 2# for the information provided. What I’m most interested in knowing is what the various numbers and letters on the steel cylinder markings mean. For example, in the code DOT-4BW240, we now know that it refers to a cylinder made to the DOT-4BW standard, and 240 indicates the design pressure of the cylinder, which is 240 Psi. But what does W.C.143# represent? What does T.W.45.2# represent? What does DT 8.7 mean? According to the requirements for pressure vessel nameplates in our country, the nameplate must indicate the design pressure, operating pressure, test pressure, operating temperature, volume, equipment serial number, etc. So, do imported gas cylinders contain this information? I would like to ask again!
