When a steam service drum is blinded, which gasket type is usually used?

When a steam service drum is blinded, the seal has to sit on a flat, full-face contact between two flanges. A flat gasket designed for boiler and steam service is the right fit because it can compress evenly across the entire face without needing grooves or special seating surfaces. The Garloc gasket is a common, proven choice for this application, built to withstand high-temperature steam and provide a reliable seal on flat faces. Ring joint gaskets require a groove in the flange to seat, which a blind flange doesn’t have. Spiral wound gaskets and generic graphite gaskets are used in other flange types or service conditions, but for blind flanges in boiler/steam service, the Garloc flat gasket is the standard, dependable option.
