How To Replace A Gasket For Flange Connections
It takes several steps to replace a gasket between two bolted flanges(flange connection).
- Before the replacement, make sure the pipeline is empty. Any residue remained inside may cause uncontrolled damage to operators.
- Loosen fasteners(bolts and nuts) in an opposite way/sequence they were tightened.
- Check again whether the line is empty before completely opening the flange connection.
- Using manual or hydraulic flange spreader to spread flange faces open.
- Remove the gasket. If some gasket parts stick to flange faces, try to scrape it away. Be careful not to scratch flange face. Clean both flange faces.
- Put on a brand new gasket. Align it to both flange faces.
- Tighten all freshly lubricated bolts in cross-over pattern.
- Clean the site and retrieve all tools.
