    They have different characteristics

  The formal name of blind flange is called flange cover, and some are also called blind flange or pipe blockage. It is a flange with no hole in the middle, which is mainly used for sealing the front end of the pipe and sealing the pipe orifice. Its function is the same as that of the head and pipe cover, but the blind seal is a detachable sealing device, and the seal of the head is not ready to be opened again. The blind flange materials include carbon steel, alloy, stainless steel, plastic, etc. the blind flange plays the role of isolation and cutting. The sealing head and pipe cover have the same function. Because of their good sealing performance, the blind flange is generally used as a constant isolation means for the system that needs to be completely separated. The blind flange is a solid body with handle, which is generally used for the general situation in the isolated system. It is more convenient to use the blind flange, which needs to be separated. The blind end needs normal operation, and the throttle ring yellow can also be used to fill the installation gap of the blind flange on the pipeline. At the same time, the identification of blind flange is obvious, which is easy to identify the installation status.

  A flange, also known as a flange or raised edge, is the part connecting the pipe, usually at the end of the pipe. There are holes on the flange. When connecting, it is necessary to fasten the two flanges with bolts. The flange is sealed with gasket to play the role of sealing, or play the role of temporary break in the experiment. Flange is a common disc part in pipeline engineering. In general, the flange is used one to one. According to different connection methods, flange is divided into threaded flange, welding flange and clamping flange. Low pressure pipeline can be connected with threaded flange, and welding flange can be used for pressure above 4kg.
