The two have different characteristics:
The formal name of blind flange is called flange cover, and some are also called blind flange or pipe plug. It is a flange with no hole in the middle. It is mainly used for sealing the front end of the pipe and for sealing the pipe orifice. Its function is the same as that of the head and pipe cover, except that the blind seal is a removable sealing device, and the seal of the head is not ready to be opened again. The flange blind plate is made of carbon steel, alloy, stainless steel, plastic, etc. the flange blind plate plays the role of isolation and cutting off. The sealing head and pipe cover have the same function because of its good sealing performance. For the system that needs to be completely separated, it is generally used as a constant vibration isolation means. The blind plate is a solid with handle, which is generally used in the general situation of the isolated system. The flange blind plate is more convenient to use and needs to be separated. The blind plate end needs normal operation. The throttle ring yellow can also be used to fill the installation gap of the blind plate on the pipeline. At the same time, the identification of flange blind plate is obvious, which is easy to identify the installation state.
Flanges, also known as flanges or raised edges, are components that connect pipes, usually at the end of the pipe. There are holes on the flange. When connecting, the two flanges need to be fastened with bolts. The flange is sealed with gasket to seal or temporarily break in the experiment. Flange is a common disc part in pipeline engineering. In general, flanges are used one-to-one. According to different connection modes, flanges are divided into threaded connection flanges, welded flanges and clamping flanges. Threaded flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4kg.
