Disclosed herein are pipe deflection gauges comprising a first guide disc having an outer circumferential edge that functions as the gauge surface, as distinguished from prior art devices, in which discrete rods or fins affixed to a central support define the gauge surface. The disclosed deflection gauges advantageously provide a cross-sectional profile having an altitude that is substantially the same as the maximum outer diameter, and therefore better align with user expectations for measurement of deflection, while being able to comply with regulatory standards by providing an accurate assessment of compliance of a particular pipe.

A drift device, including a cylindrical main body having a hollow inner cavity, a front portion including a channel configured to receive a bumper, the cross bar including a central indentation, and a rear portion. The rear portion may include a plurality of openings or selectively removable panels. The cylindrical main body, the front portion, and the rear portion are formed together as a single piece.

A floating drift apparatus for verifying the inner diameter of tubulars as the tubulars are made up into a tubular string being run into a wellbore. A float section provides buoyancy to float the apparatus in fluid within the bore of a tubular, and a drift section has a drift element with a diameter substantially equal to the tubular inner diameter being verified, which may be the drift diameter. When running a tubular string, the apparatus is inserted into the bore of the tubular string, floating in the fluid. As joints of tubular are made up and run into the wellbore, the tubulars move downhole around the apparatus. Preferably, the floating drift apparatus can be visually detected. If an undersize ID is encountered, the floating drift apparatus will be pushed downhole and no longer visible; the operator can remove the undersize ID tubular from the string.

A trim gauge for inspecting the dimension of a workpiece includes a body having a first body portion and a second body portion, the second body portion having a thickness smaller than the first body portion. The trim gauge also includes a first flange coupled to the second body portion and extending radially outwardly of the second body portion. A thickness of the first flange corresponds to a lower acceptable limit for the measured dimension of the workpiece. The trim gauge further includes a second flange coupled to the second body portion and extending radially outwardly from the second body portion. A thickness of the second flange is smaller than the first flange and corresponds to an upper acceptable limit for the measured dimension of the workpiece.
