Quick-action blinding devices
For process safety reasons, it is sometimes necessary to blind the piping, i.e., to install a blind flange in it. Conventionally, so-called spectacle blinds are used for this purpose; the method is quite labour-intensive and time-consuming, especially in confined spaces and in the case of large size classes.
Quick and safe blinding
The ONIS quick-action blinding device consists of two body halves fitted with flanges or welding ends connected to each other by means of eccentric bolts and a connecting plate. The most significant advantage of this system is that a single person can easily turn a lever or a hand wheel to blind even piping of nominal size DN 1200.
Such simple operation of the device improves occupational safety, shortens downtimes and reduces the need for labour during the blinding operation.
