Abstract
A liner hanger seals with casing stringhaving mill scale and supports a linerwithin a well. The liner hanger includes a tubular anchorand a tubular expander. The tubular anchormay be positioned in the casing stringusing an inner mandrel. An actuator assemblyforcibly moves the tubular expanderinto the tubular anchor, expanding the tubular anchorto grippingly engage the expanded tubular anchoragainst the casing stringand to form a circumferential seal between metal sealing elementson the tubular anchorand the interior wall of the casing string. The metal sealing elementis oversized to provide rigidity, heat shrunk onto the tubular anchor, and abrasively dressed to remove excess material prior to installation of the liner hanger.
