ASME B16.5 Spectacle Blind Flanges are generally applied to permanently separating pipe systems, or they could even be used to just connect with each other. Spectacle blinds are a type of fitting, which consists of a steel plate that has been cut into two discs of a certain thickness. Click the link given here to know more about the spectacle blind flange price.
The two discs as mentioned in the spectacle blind flange weight chart are attached to each other by section of steel, which is similar to the nose piece of a pair of glasses. Hence the term spectacle blind. One of the discs in the precision flange spectacle blind is a solid plate, while the other part is a ring, whose inside diameter is equal or similar to that of a flange.
ASME B16.5 Spectacle Blind Flanges could be applied in systems, which regularly require to be separated i.e. assembling and dis- assembling from other installations. Normally, a spectacle blind flange flat face will be typically mounted in the open position so that flow of the media passing through the pipe is possible and not hindered. However, if the spectacle blind flange pn16 in the close position has been rotated, then , the pipe is blanked off and no flow is possible to any direction.

Maintenance on a pipe system can be a reason to rotate the spectacle blind flange in the close position by the factory workers. This run will take place through the hole, that has been drilled in the connection piece by the spectacle blind flange manufacturers in india . By loosening of all bolts, and partial removal of their, the spectacle blind flange raised face could be rotated. After replacing the gaskets the bolts can be re-assembled and tightened in the piping system. Although we recommend using a new gasket every time this has to be done in a stainless steel spectacle blind flange.
The ASME B16.5 spectacle blind flange rtj with pressure rating class designations i.e. class 150, class 300, class 400, class 600, class 900, and class 1500 in a size range between NPS 1/2 up to NPS 24 and piping spectacle blind flange with pressure rating class designation class 2500 is available in sizes NPS 1/2 till NPS 12. The requirements of the ASME B16.5 spectacle blind flange rf has been given in both metric as well as the U.S. Customary units with diameter of bolts and spectacle blind flange material bolt holes expressed in inch units;
We are one of the leading exporters of the spectacle blind flange supplier in Malaysia. We also supply other components besides the spectacle blind flange Singapore.
