Blind plate ticket
Thread Content
I would like to ask everyone: how should the material and specifications of the blind flange be filled in when issuing a blind flange order? Specifically, I’m not sure how to enter the material information for the blind flange; are there any resources available where I can find this information?
The blind plate standards correspond to the flange standards; one standard is recommended: HG2092--20653, or the standards from the petrochemical industry can also be chosen.
