The blind plate is mainly used to completely isolate
the production medium to prevent the shut-off valve from being
closed tightly, affecting production, and even causing accidents.
The blind plate should be set in the part where isolation is
required, such as the equipment nozzle, before and after the
shut-off valve or between two flanges, and it is often recommended
to use a figure 8 blind; Insert plates (round blinds) can also be
used for single-use parts such as pressing and purgingIt is
generally divided into four types: forging, casting and forging,
medium plate cutting, and casting. Among them, the price of forging
products is the highest, followed by medium plate, and casting and
forging are the lowest. Casting is the most secondary process. And
the quality is good for forging and medium plate, and casting and
forging is slightly worse. 1. In the original start-up
preparation stage, when the strength test or tightness test of the
pipeline is carried out, it cannot be carried out simultaneously
with the connected equipment (such as turbine, compressor,
gasifier, reactor, etc.), and a blind plate should be set at the
connection between the equipment and the pipeline. 2. When the
device stops, if the pipeline is still running, a blind plate is
set at the shut-off valve. 3. When the device is a multi-series,
the total pipeline from outside the boundary area is divided into
thousands of pipes into each series, and a belly plate is set at
the shut-off valve of each sub-pipeline. 4. When the device is to
be regularly repaired, inspected or switched to each other, when
the equipment involved needs to be completely isolated, a blind
plate is set at the shut-off valve. 5. When the process pipeline of
pressure filling pipeline and replacement gas pipeline (such as
nitrogen pipeline and compressed air pipeline) is connected to the
equipment, a belly plate is set at the shut-off valve. 6. The low
point of equipment and pipelines is cleaned, if the process medium
needs to be concentrated in a unified collection system, a blind
plate is set after shut-off valve. 7. The exhaust pipe, liquid
discharge pipe and sampling pipe of the equipment and pipeline
should be set with blind plates or wire plugs behind the valve.
Except for non-toxic, non-hazardous to health and non-explosive
materials. 8. When the device is constructed in phases, there are
interconnected pipelines set up at the shut-off valve to facilitate
subsequent engineering construction. 9. When the device is in
normal production, some auxiliary pipelines that need to be
completely cut off should generally also be set up with blind
plates. [1
