Inspection at the rig CJ-CSM can inspect EUE & NU tubing, drill pipe, OD/ID coated tubing, and casing in any size while tripping out of the well. The inspection detects wall loss and gains (rodwear, key seat), cracks, notches, corrosion (CO2, H2S, external, internal), fatigue build up, critically flawed areas, gouges, material changes, mechanical damage, and stress concentrators.
