    In the majority of cases boiler tubes are expanded, and then bell-mouthed into drums or headers. For large diameter tubes, such as downcomers, grooved seats are used to assist the expansion in forming a tight seal. Where high temperatures are involved, as with superheater tubes, welding may be used in place of expanding. Tubes Attachments
