What problems should be paid attention to when installing the blind plate?

Before maintenance, the closed equipment should be cut off with a blind plate to cut off the inlet and outlet pipelines connected to it, so that the operating equipment is completely isolated from the equipment to be repaired. This blind plate must be able to withstand the working pressure of the pipeline, otherwise the pipeline needs to be disassembled , or install a vent pipe and a pressure gauge between the blind plate and the valve, and send a special person to guard it to avoid the pressure in the pipe gradually rising due to the leakage of the valve, and the blind plate will be crushed.

Talking about the processing flow and performance characteristics of high pressure flange

Talking about the processing flow and performance characteristics of high pressure flange

The processing methods of high-pressure flanges are complex, and it is necessary to pay attention to the relevant characteristics and specifications in the processing process to avoid the divergent state of the processed high-pressure flanges. The American standard flange is the part that connects the pipe to the pipe, and is connected to the pipe end. There are holes on the American standard flanges, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. American standard flanges can be cast or threaded or welded.
