Abstract
A power tong assembly has a power tong and a backup for making up and breaking out of threaded tubular connections in tubulars such as drill pipe. The power tong assembly has an overall geometry, including but not limited to a jaw die shape, which reduces contact forces on the tubular, and on the tong body. Preferably, the dies have teeth which are angled to enhance engagement on the tubular. Crush zones or pockets may be provided on the dies, to permit deformation against hard banding on tubulars. In some embodiments, the tong jaws permit mounting the dies in different longitudinal (vertical) positions. In some embodiments, the fixed jaw within the backup has angled sidewalls which accommodate a broader tubular OD range. A cutout in the power tong cage lower plate permits a thicker tong rotary for a given overall tong assembly height.
