Abstract
A hanger comprising two tubular sections, one partially received within the other, one section having a serrated surface and the other section retaining at least one detent whereby the axial length of the hanger is adjustable. This arrangement obviates the disadvantage in the conventional tie-back method of sub-sea wellhead completion wherein it is necessary to cut and dress the casing after pulling tension in the casing string.
