4″ to 14″ Diameter Spectacle Blinds for Process Piping

November 10, 2009

Sweco Fab, Inc., a division of PT&P, fabricated a variety of six spectacle blinds that will be used for selective line isolation. The spectacle blinds are fabricated from A516-70 carbon steel with sizes ranging from 4″ to 14″ diameter and per ASME B16.48 code. The function of a spectacle blind is to allow a line to be in either full shut-off mode or full flow mode, depending on which side is being utilized. Spectacle blinds are a lower cost alternative to double block and bleed valves where OSHA requires positive isolation of piping segments for safety reasons.
