If a blind plate diagram is to be created?
Thread Content
Could we talk about how to create a blind plate diagram? I’m a beginner who is just starting to work with blind plate management. Initially, it’s necessary to create a blind plate diagram, but I’m not sure what aspects need to be taken into consideration.
Are you referring to a blind flange? Go and look up the corresponding standard, and follow the diagrams in it.
Generally, when starting up, shutting down, or carrying out maintenance work, blind plates need to be removed and installed, and blind plate diagrams must be drawn. Therefore, I would like to ask if there are any guidelines or standards for creating such diagrams.
At the beginning, you should check the relevant manuals to see what’s in them
Oh, it’s temporary then; in that case, draw it based on the dimensions of a blind flange. The key is to use the exact values for the outer diameter, bolt hole diameter, and bolt hole pitch circle – they must match exactly. Check which standard your project intends to use; for American standards, you can refer to ASME B16.5.
Does the poster mean the blind plate dimension diagram? :o
Is it the blind plate diagram on the flow chart, marked according to the location where the blind plates are removed or installed on-site? For starting and stopping?
Aren’t there **standards**? Just follow the standards and that’s correct
This post was last edited by qwl on 2016-12-2 09:23; the thickness of the blind plate is determined based on calculations. Frequent switching can be used to create 8-character blind plates. A batch of standard blind flanges was machined, marked, and stored; temporary blind flanges were made on-site for use. Most of these temporary flanges got lost after work started, and it was necessary to create new ones again during shutdowns, resulting in costs in terms of materials and labor.
What the original poster is mainly asking about is the blind plate management diagram, that is, the management of installing and removing blind plates during startup and shutdown. This is usually indicated clearly on the process diagram to facilitate pipeline management
