|Visual Tube Body Inspection
||A thorough visual inspection of pipe
external surface for possible noticeable damages, such as dents, mashes
and corrosion/ pits, shall be performed from end to end. Visual inspection
includes internal end area of each tube for service induced defects.
The tubes are checked for straightness.
|Visual Thread Inspection
Thread Protectors are removed and both pin
and box ends are thoroughly cleaned and visually evaluated for any
obvious defects or mechanical damages, such as dents, corrosion,
galled threads, etc.
Thread profile gages are used to estimate the visible gaps at any
of the flanks or thread roots.
API Dope is applied to the threads and thread protectors are installed.
The dope shall be supplied by the customer.
|OD Gauge (Full Length)
||Full length mechanical measurement of outside
diameter is performed for identification of external wear, dents,
mashes, slip area and stress induced diameter variations.
|Magnetic Particle Inspection (MPI)
||Pipe is magnetized with a DC magnetizing coil
with variable current to provide active longitudinal magnetization
for detection of transverse flaws.
|Wall Thickness Measurements
||Ultrasonic Measurement: Ultrasonic
wall thickness tests are utilized to determine the minimum and maximum
wall thickness at any one area on a tube. A test consists of taking
as many circumferential measurements as required to determine the
minimum and maximum wall thickness in one area.
Measurement: Micrometer measurements are utilized in measuring
the wall thickness on the ends of plain end pipe.
Wall Verification: Ultrasonic wall thickness test to verify
that the tube body, in general, satisfies nominal wall thickness requirements.
||The connections are mechanically gauged using taper, lead and height
gages to detect galled or stretched threads, flank wear and sharp
crowns and to verify the connection is within API Specifications.
|Magnetic Particle Inspection Box & Pin Threads
||Box and Pin threads are cleaned and inspected
by either magnetic particle or black light to detect transverse cracks
in thread roots.
||Seals found to be damaged or corroded are refaced
to the limitation of API RP 7 G.
|Heavy Weight Drill
Pipe & Drill Collar Maintenance Services
||Wire brushing or rattling to remove rust, scale
and other debris.
||Bent pipe is straightened using a ram type hydraulic
||A rust preventive coating is applied to maintain
the integrity of the drill pipe.
|TH Hill DS 1 Inspection
|If the customer requires DS-1 inspection,
Omega Pipe Inspection & Services can perform the inspection accordingly.
