ASTM A182 F53 / UNS S32750 Super Duplex Steel Ring Spacers Flange
Ring spacer flanges, also known as a spectacle blind. A ring spacer flange consists of a metal ring that is placed between two flanges, effectively "spreading them apart." This is commonly used to temporarily or permanently isolate a section of a piping system, providing a break in the line without the need to physically disconnect or remove sections of pipe. These flanges are frequently employed in applications where maintenance or repairs are required downstream of the spacer. By inserting the ring spacer and a blind flange, the flow is stopped in that section of the pipeline, allowing for safe maintenance or repair activities to proceed without needing to shut down the entire system.
