BTC STC LTC Thread Coupling according
Kingwell tube and tool joint inspections are carried out in accordance with standards like API Inspections of drill pipes, casings, tubings or tools are usually performed based on the following international standards:
· API, API 5CT, API 5L
BTC STC LTC Thread Coupling Detail:
Visual Tube Body Inspection
A thorough visual inspection of possible noticeable external damages inflicted is performed; most damages encountered arise from handling of the casing,
such as major dents and mashes. Other types of flags will be external corrosion, laps, and straightness.
Visual Thread Inspection
(API & Premium Connections)
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.
Premium threads are inspected to evaluate the condition of the seals, threads and for any mechanical damages like dents, corrosion, galled threads, etc.
API Dope is applied to the threads and thread protectors are installed. The dope shall be supplied by the customer.
API Drifting (Full Length)
Drift mandrels conforming to API Specifications are passed through the full length of each tube to assure compliance with API internal diameter
specifications. If a mashed or dented area prevents drift, the location is noted on the inspection report and marked physically on the pipe.
Special Clearance Drift – Full Length
Special clearance drift mandrels, furnished by the customer, are passed through the full length of each tube to determine special clearances on the
internal diameter. This is not an API inspection and is usually performed to assure passage of special tools or oversize bits.
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.
Electromagnetic Inspection (EMI)
Buggy Inspection Unit is used for transverse defect inspection.
Portable Hardness Testers are utilized to perform hardness reading on the pipe.
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.
API Thread Gauging
API eight round and buttress threads are gauged with mechanical instruments to determine compliance on taper, lead and height. At the same time,
the threads are examined for visual defects.
