What is the difference between flange and flange blind plate

Flanges are officially called flanges, and some are called flanges or stoppers. It is a flange without a hole in the middle, mainly used to seal the front end of the pipe, used to seal the nozzle. Its function and

The head is identical to the sleeve except that the blind seal is a detachable seal and the head seal is not ready to be opened again. Blind plate materials such as carbon steel, alloy, stainless steel, plastic, etc
Isolation, cutting effect, sealing head, sleeve functions are the same, because of its good sealing performance, can be completely isolated from the system, generally used as a constant isolation method, blind plate is solid with a handle
Body, commonly used in isolation systems. The flange blind plate is more convenient, need to separate, use the end of the blind plate, need normal operation, use the yellow throttle ring, can also be used to fill the blind plate on the pipe
The installation clearance. At the same time, the flange blind plate is clearly marked, easy to identify the installation state.
Flanges, also known as flanges or raised edges, are the parts that connect pipes, usually at the end of the pipe. Flanges are perforated and the two flanges need to be bolted together when they are connected. Flange using pad
Chip seal, which acts as a seal or a temporary damage in the experiment. Flange is a common disk part in pipeline engineering. Usually, flanges are used in pairs. According to different connection modes, flange points
They are threaded flanges, welded flanges and clamping flanges. Low pressure pipe can be threaded to flange, more than 4 kg of pressure with welding.
