Need help with PID diagrams! What does the ball valve symbol on the PID piping diagram mean?
Thread Content
As shown in the figure: this is a PID diagram of a ball valve on a pipeline. The identifier “BA2CRRI” is displayed on the ball valve – what does this identifier mean? Like pressure rating? Size? Materials? What standards were used?
These are the PID drawings designed by the Ocean Engineering Design Institute; what version of the valve specification sheet is being used? Is there a naming convention?
When looking at the drawings, start by examining the legend and design specifications
In fact, that’s all the drawing information provided by the design institute. . There is also a list of ball valve manufacturers recommended by the owner

This should be CNOOC’s drawing. The identifier is specified by CNOOC’s internal EDIS regulations
B stands for ball valve, A stands for 150lb, 2 stands for carbon steel; I forgot the rest
Oh, I see! ! Where can I find the relevant documents regarding CNOOC’s internal EDIS regulations and standards?
This can be requested directly from the design institute; the drawings need to be clear not only for the design institute itself, but also for others.
