- product description
-
Spectacle Blind is a pipe fitting, usually used for pipe flanges that need to change processes or isolate media. Its shape is similar to the figure "8", with half of it being a blind plate and the other half being a ring passage.
Standards: HG/T 21547-2016, HG/T 20570.23, SH/T 3425-2011, API 590, ASME B16.48Main uses include:
1. Complete isolation: used to completely isolate the production medium to prevent production from being affected or accidents caused by the shut-off valve not being closed tightly.
2. Clear identification: By switching between the blind plate and the passage, it is possible to intuitively determine whether the pipeline is in an isolated state.
3. Inspection and maintenance: commonly used for the commissioning and standby state switching of equipment such as heat exchangers, reactors, and nitrogen pipelines.
4. Temporary isolation: used to isolate pipelines that do not require circulating media when the device is started or stopped.
