Drill collar Detail:


Drill collar inspection services:

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. 

Micrometer Measurement: Micrometer measurements are utilized in measuring the wall thickness on the ends of plain end pipe.

Ultrasonic Wall Verification: Ultrasonic wall thickness test to verify that the tube body, in general, satisfies nominal wall thickness requirements.

Thread Gauging

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.

Refacing

Seals found to be damaged or corroded are refaced to the limitation of API RP 7 G.
