A mechanical or hydraulic actuated liner hanger for supporting on an operating string to be lowered to position a liner on a tubular member in a well bore includes an integral tubular body having upper and lower annular rings thereon. A surface is provided on each ring to enable upper and lower cone segments to be positioned on each upper and lower ring, respectively, and a surface is provided on each ring that cooperates with a surface on the cone segments interlocks and retains the cone segments removably on their respective ring. A securing device may removably secure the cone segments in position on each ring. A sleeve is slidably supported on the body by lugs on the body and a recess arrangement. The sleeve includes upper and lower slip arms secured at one end on the sleeve and extending therefrom with upper and lower slip segments secured on the end of each the upper and lower slip arms. When relative longitudinal movement between the sleeve and longitudinal body is effected, the slip segments engage with the cone segments on each the upper and lower rows for movement outwardly into engagement with the tubular member to position the liner in the well bore. The same body may be employed with the hydraulic or mechanically actuated hanger. The same sleeve, lug and recess arrangement may be employed with either a mechanical left-hand set or right-hand set rotatable liner hanger. The same body and other components, with the exception of the slips and cone segments can be employed with any size liner and any size pipe. The only parts of the mechanical hanger components that may need to be changed with varying size and weight of pipe are the slip segments and the cone segments which can be removably replaced to function with the pipe size and weight with which the liner hanger is to be employed.
