The invention relates to a method and apparatus for shape cutting a pipe end. An arched cutter (4) of a punching tool (3, 4) is inserted into an end of a pipe (1) for penetrating the same into a wall of the pipe (1) in a plane of the arched cutter. Then, the punching tool is displaced in a direction perpendicular to a center axis (C) of the pipe (1), whereby the arched cutter (4), while moving outwards from inside the pipe, shears off a piece that matches its shape. The punching tool (3, 4) is withdrawn out of a pipe end, the punching tool is rotated 180, it is re-inserted into the pipe end and the punching tool (3, 4) is displaced in a direction which is perpendicular to the pipe center axis (C) and opposite to the previous displacement direction, thus enabling the shearing off the pipe end a second piece matching the shape of the arched cutter (4).

Described herein is a cutting apparatus (100) for allowing visual inspection of a core sample in an inner tube at a drilling site after the inner tube has been removed from a coring tube and prior to it being transported to a laboratory. The cutting apparatus (100) comprises a support track (110, 112, 114, 116)) on which is mounted a tube support member (120), a cutter wagon (130, 132, 138) and a drive arrangement (140, 142, 144, 146). The apparatus (100) provides relative movement between an inner tube (150) and the cutter wagon (130, 132, 138) to allow a section of the inner tube (150) to be removed along its entire length for visual inspection. The drive arrangement (140, 142, 144, 146) provides the relative movement between the inner tube (150) and the cutter wagon (130, 132, 138).

Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.
