Features of Blind Flanges.
A blind flange can replace a butt weld cap in case an extension of the piping line is required, or in case a piping inspection is required (remove the blind flange to access the pipe interior). This type of flange can also be used as the rod access point on drain systems. Depending upon the application, a blind flange may be drilled and used as a slip-on flange, or tapped and used as a threaded flange. Its connection mode is to connect with the flange, and its main function is to block the pipe. It is a bit similar to the head and cap in the pipe fitting, but it is different from theirs because the place with the flange cover is a “live” pipeline. After all, it can be disassembled when in use, and can be blocked when not in use, Because it is fixed by bolts, it is also very convenient to remove.
