Abstract: A calibration system is provided for calibrating acoustic transducers such as phased array acoustic transducers and time of flight acoustic transducers. In one embodiment, a calibration block is provided with predetermined calibration features defined therein. The calibration block may be provided with guide surfaces or engagement surfaces utilized to position the transducers accurately with respect to the calibration features so that the same acoustic scanning views are consistently produced. In one embodiment, the guide surfaces define a recessed region for acoustic couplant. The outputs can be combined to produce an image and compared to a known image to verify that the acoustic transducers are all oriented properly and calibrated for operation.

Abstract: Lubricant escape passages are formed in the threads used to connect one tubular body to another. The passages conduct trapped thread lubricant out of the threaded area to prevent the creation of high lubricant pressure that may damage or cause improper make up of the threaded connection. The passages may be grooves in the crests of the thread teeth and/or may be corner bevels on the thread teeth. In a conductor pipe or other pipe assembly using axially spaced internal and external seals at each axial end of the threaded area, the escape passages form a helical flow path through the engaged thread area. The external seal prevents the entry of corrosive fluids into the threaded area and the internal seal prevents leakage through the threaded area from within the conductor pipe. When the lubricant pressure increases excessively during assembly or impact loading of the connection, the lubricant escapes past the seals to prevent connection damage.

Each of the pin and box tool joints includes a thread for mating engagement and preferably first and second shoulders. The drill pipe has a ratio, R, which takes into consideration the pipe inner diameter, PID, the pipe outer diameter, POD, the tool joint inner diameter, TJID, and the tool joint outer diameter, TJOD. This ratio may be expressed as: R = ( P ID + TJ ID ) ( TJ OD - P OD ) . According to the present invention, this ratio is greater than 8.0, and is preferably from 8.1 to 8.5, thereby providing a drill pipe with desired strength and fluid flow capabilities.
