Product Details
blind flange
Blind flange is also called blind plate, also known as flange cover. It is a flange without a hole in the middle, used to block the pipe mouth
From the appearance of the blind plate, it is generally divided into plate flat blind plate, 8-shaped blind plate, insert plate, and backing ring (insert plate and backing ring are blind to each other). The blind plate plays the role of isolation and cutting, and the role of the head, pipe cap and welding plug is the same. Because of its good sealing performance, it is generally used as a reliable isolation method for systems that require complete isolation. A flat plate blind is a solid circle with a handle for systems that are normally isolated. The 8-shaped blind plate is shaped like an 8-shaped blind plate, one end is a blind plate, and the other end is a throttle ring, but the diameter is the same as the pipe diameter, and does not play a throttling role. The 8-shaped blind plate is easy to use. When isolation is required, the blind plate end is used. When normal operation is required, the throttle ring end is used. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is the obvious identification, easy to identify the installation status.
Common implementation standards for blind plates: GB/T 9123-2010 HG20592-2009 HG20601-97 JB/T86.1-94 D-GD86-0513 ASME B16.5, etc. Can be customized production parameters according to customer requirements.
