Casing and Tubing Inspection
Our inspections meet or exceed API requirements, follow documented Standard Operating Procedures and safety protocols. We inspect all casing & tubing sizes, pup joints.
Visual Body Inspection
We perform visual inspection of ID and OD of all tubings and casings for obvious external damages such as external corrosion, dented, mashed, or bent tubes. Most damages arise from handling of the tubular.
Visual Thread Inspection
We thoroughly clean and visually inspect and evaluate both pin and box end connections for any damages, such as pitted, cut or mashed seals, galled threads, corrosion, coating integrity, etc. Any defects noted will be clearly marked on the area and identified on the inspection report.
Full Length Drift for API & Premium Connections
API Drift and Premium Drift cut to strict specifications, is passed through the full-length bore of each length of pipe in order to check for mashed or dented areas along the pipe. If an area has been located, the defect will be noted on the inspection report.
Full Length Magnetic Particle Inspection
The procedure for performing the FLMPI describes the recommended methods of inspection of ferromagnetic new casing, tubing, couplings, and plain end drill pipe.
Special End Area (SEA)
The special end area inspection is designed to detect transverse and longitudinal defects on the inside and outside surfaces of the end areas including the pins, couplings, threads and upsets. This inspection is principally for critical inspection of special upsets, integral connections and ends of high-strength pipe. In addition to MPI, the exposed threads and end areas are visually scanned for conspicuous irregularities, such as damaged threads, chamfer and black-crested threads.
Ultrasonic Thickness Gauging
Ultrasonic examination of upset areas for detection of transverse and three dimensional flaws on the inside and outside of the tubes.
A hardened and precision ground profile gauge is mated to all threads at a minimum of four locations around the circumference of the threads to confirm the proper thread form. Lead, taper, and thread depth measurements can also be taken
