Everyone, please help – what does this mean?
Thread Content
I don’t understand the specifications, models, materials, etc. of these valves. Could everyone please help explain what each line and each field means?
The table headers are in order: Serial Number, Quantity, Size, Grade, Description, Material, Valve Tag.
The first one is a corner valve, and the one behind it is a ball valve; both are connected via threads.
I know all these characters; it’s mainly the parameters below that I don’t understand, such as 4000#, 330J-NQ, AN3402
4000# refers to a grade of 4000 pounds; as for the material 330J-NQ, I’m not familiar with it – perhaps someone who knows about valves can explain it. AN3402 is the designation; the valve you provided will be used in a location designated by this code.
Thanks, I’ve given you all the extra points I could
It’s okay, it’s the system’s allocation; thank you anyway
Serial number, quantity, bore size, pressure rating, valve type description (corner valve, ball valve with threaded connection), material, tag number.
I recognize all these characters; it’s mainly the parameters below that I don’t understand, such as 4000#, 330J-NQ, DHV NACE, WKM NACE
You need to check the material yourself; everything else mentioned above is correct. All of these weight classes fall under high-pressure pipelines
Where can I check it? Are there standards and manuals?
