Like most flanges, a spectacle blind flange is used to connect or disconnect piping systems. This is made possible by the design of these components, which look like a spectacle. Hence, the term is used by all spectacle blind flange manufacturers around the world. The design of this flange includes 2 circular disks. One disk is similar to a blind flange, which is used to cause a permanent or temporary termination of flow. And the other disk is hollowed out in the center such that its inner diameter matches that of the pipe in a system.
When the hollowed plate is turned and connects the pipe, it is referred to as the open position, Whereas in the instance of the solid plate of the A105 Spectacle Blind flange covering the pipe, it is referred to as a closed position. One of the benefits of using this device is that it can be switched from open to closed position on a regular basis by the simple loosening of a bolt that is seen on the part that connects the two discs. The thickness of both the discs in the Asme 16.48 Spacer Blank Flanges are to be the same. Similar to all the components in a piping system, the material used by the manufacturer in its production must meet the requirements of the applications. If the application calls for high tensile strength, where hardness is not to be compromised, using a Carbon Steel Spectacle Blind Flange would meet its requirements. Furthermore, the price of these flanges would be much lower than other conventionally used alloys including stainless steel or any Alloy steel Spacer Blank Flange. Some other applications have the need for better corrosion resistance properties and more flexibility with regards to temperature usage. For such applications, the SS Spectacle Blind Flange is a viable option.
