such as the liner 14 selected to be placed within a larger diameter tubular such as the casing 10 already in position within a well a spacer 16 may first be positioned about the liner 14 adjacent one end particularly if the necessary expansion of the liner 14 would otherwise be excessive the spacer or spacer elements are selected to extend substantially the length of the portion of the liner 14 to be expanded ductile sealing material may be added about the liner where a spacer is present such ductile sealing material may be either inwardly of the spacer 16 or outwardly of the spacer 16 or both once the tubular has been prepared a tubular expander is placed therein a tubular expander is selected with the appropriate piston stroke to expand a preselected length of the liner 14 the draw bar 38 is extended such that the widest area of the collet 54 is in location to expand the desired portion of the liner 14 with a spacer involved the collet is arranged just longitudinally outwardly of the spacer 16 with the appropriate length selected the shoulder 82 on the hydraulic ram 32 abuts against the near end of the liner 14 some pressure may be supplied to the central bore 40 so as to set the collet 54 within the liner 14 with enough force so that the entire liner assembly can be supported by the collet 54 as the assembly is lowered into the well once in position with the liner 14 overlapping the casing 10 at least to the extent of the spacer 16 high pressure fluid is directed down the drill pipe to the central bore 40 of.
