Beschreibung
Zusammenfassung:	A pipe wrench for making-up or breaking-out a threaded connection between a first tubular member and a second tubular member includes an upper wrench assembly with a pair of upper jaw assemblies configured to grip the first tubular member and a lower wrench assembly with a pair of lower jaw assemblies configured to grip the second tubular member. The upper and lower wrench assemblies are concentrically constrained, axially overlap, and radially engage with one another. Each of the upper and lower wrench assemblies independently includes a frame with a curved segment containing an arc at an angle of about 160 to about 200. The upper and lower wrench assemblies are configured to rotate the first tubular member relative to the second tubular member and can have an angle of rotation in a range from about 75 to about 180.
