Application of the Blind Plate 1. In the initial 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 turbines, compressors, gasifiers, reactors, etc.) Next, a blind plate needs to be installed at the connection between the equipment and the pipeline. 2. For various process material pipelines connected outside the bounded area to the bounded area, when the device is shut down, if the pipeline is still in operation, a blind plate is installed at the cut-off valve. 3. When the device is multi-series, the main pipeline from outside the boundary area is divided into several sub-pipelines to enter each series, and blind plates are installed at the shut-off valves of each sub-pipeline.
4. When the device needs to be regularly maintained, inspected or switched between each other, and the equipment involved needs to be completely isolated, a blind plate should be installed at the cut-off valve. 5. When the pressurized pipeline, replacement gas pipeline (such as nitrogen pipeline, compressed air pipeline) and the process pipeline are connected to the equipment, a blind plate is installed at the cut-off valve. 6. The low points of equipment and pipelines should be drained. If the process medium needs to be concentrated into a unified collection system, a blind plate should be installed behind the cut-off valve. 7. The exhaust pipes, drain pipes and sampling pipes of equipment and pipelines should be equipped with blind plates or plugs behind the valves. Non-toxic, non-hazardous to health and non-explosive materials are excluded. 8. During the phased construction of the device, blind plates shall be installed at the shut-off valves for interconnected pipelines for subsequent construction. 9. During the normal production of the device, some auxiliary pipelines that need to be completely cut off should generally be provided with blind plates.
