Eight-character blind plate
Thread Content
What are the advantages of using eight-character blind flanges in the process?
When internal leakage occurs in the valve, the process medium can be completely isolated
1. Facilitates the insertion and removal of blind plates. 2. Makes it clear whether there is a blind plate between the flanges or if they are connected directly (if there is a ring on the outside, then there is a blind plate in between the flanges; otherwise, not). . ）
The 8-character blind plate is a standard type of blind plate. There are several advantages to using an 8-character blind plate: 1. It is thick enough, ensuring absolute safety. 2. Due to its thickness, a large gap is created during disassembly, so an 8-shaped blind plate needs to be used as a filler. 3. Not easy to lose. The blind flanges we usually talk about are manufactured by ourselves, and they don’t count as standard blind flanges.
1. Generally, blind plates are required to be installed on valves at the boundaries of a plant, in order to safely isolate the medium during maintenance work on the plant. 2. Before starting up a plant, pressure tests are carried out; blind plates are used during these tests. However, after the testing is complete, these blind plates are removed, which creates gaps between the pipes, after which diagonal blind plates are installed.
Reply to 4# string_0: Could you provide an image to illustrate what a standard blind flange looks like? I’m still learning about this. In normal production, such flanges are usually made manually, using either stainless steel or carbon steel plates
