54. DRILL COLLARS, KELLY AND STABALIZERS, FULL LENGTH MECHANICAL OPTICAL & END AREA INSPECTION
The outside surface of the tool is cleaned and visually examined for defects. The inside surface of the tool is examined with
proprietary camera or optical instrument for visible defects, the ends are inspected as described in Dry Magnetic Particle End Area Inspection.
55. DRILL COLLARS AND SUBS
Visual connection, dimensional 3, and blacklight inspection of connections Category 3-5, as described in service line 34.
56. CORE BARRELS MECHANICAL OPTICAL & MAGNETIC PARTICLE INSPECTION
Dry magnetic particles applied according to Technical Industries, Inc. specifications inspection procedures for full length
excluding end areas is performed on ferromagnetic material. The outside surface of the tool is cleaned and visually examined for defects. The inside surface of the tool is examined with
proprietary camera or special optical instrument for visible defects. The area to be inspected must be thoroughly cleaned
before beginning the inspection process. After a visual thread inspection is performed, a DC magnetic field properly
oriented according to the inspection being performed, is induced into the pipe. Dry iron powder is applied to the area.
Any accumulation of powder at the point of flux leakage, caused by an anomaly, will be probed. Should the anomaly be insufficient
for rejection of the material, the imperfection if accessible will be removed and the area contoured.
57. DRILL BIT INSPECTION, MECHANICAL OPTICAL & MAGNETIC PARTICLE INSPECTION
Same as in service line 53 procedure will be applied.
