Spectacle Blind Flange
KEYSWON spectacle blind flanges are composed of a blind disk at one end for isolating the flow and a throttling ring at the other end for allowing the flow to pass through the pipeline. This pipe fitting can serve the function similar to a stop valve to block the flow if a valve leakage happens. It can be used as a reliable isolation means for pipeline systems that require complete isolation as it has outstanding sealing performance.
Advantages
Our spectacle blind flange is a high quality pipeline component and can help prevent the wasting of processing materials. High dimensional accuracy and low surface roughness make this flange ready for installation without additional machining. Its enhanced mechanical properties remove the need for heat treatments.
Our spectacle blind flanges are designed with NPS of 1/2~40" and nominal pressure class of 150~2500lbs.
