Abstract: A tool for determining variations in outer diameter of a pipe. The tool may have a pair of contact arms configured for engaging with opposing sides of a pipe. The contact arms may be biased toward one another, and at least one of the arms may be configured to slide toward and away from the other. As the contact arms are moved along an outer surface of a pipe, a distance between the arms may change in response to variations in outer diameter of the pipe. A plunger gauge may be arranged on one of the contact arms with its plunger directed toward the other arm. The plunger may extend or depress in response to a decreased or increased distance between the contact arms. An alignment shoe may align the contact arms with at least X and Z axes of the pipe so as to help ensure accurate pipe measurements.

Abstract: A system and method for measuring a pipe is provided. The system includes a frame rotatably receiving the pipe, a carriage movably positionable along the frame, a guide floatingly positionable about the carriage, at least one sensor for measuring a position of the pipe, and a measurement unit operatively linked to the sensor for collecting measurements therefrom. The guide has a mouth that receivingly engages the pipe and axially aligns therewith. The pipe is measured with the sensor(s) while moving at least one of the pipe, the carriage and the guide.

Abstract: An ultrasonic probe apparatus for detecting flaws in a tubular includes a probe house. The probe house has an axial axis, a central cavity lying along the axial axis, and a bottom face adapted for placement on the tubular. The bottom face of the probe house has an opening in the middle. A probe support is disposed within the central cavity and rotatable about the axial axis of the probe house. An ultrasonic probe is mounted on the probe support and has a scanning face exposed to the opening of the bottom face of the probe house. The scanning face is tiltable relative to a selected plane of the tubular by rotation of the probe support about the axial axis of the probe house.

Abstract: A plurality of magnetic field members are provided, each for selectively generating a time-varying magnetic field for combination into a o time-varying composite longitudinal magnetic field with magnetic flux lines which are substantially aligned with the central longitudinal axis of the cylindrical ferromagnetic member. Additionally, a traverse magnetic field member is provided which selectively generates a time-varying traverse magnetic field with magnetic flux lines which are substantially traversed to the central longitudinal axis of the cylindrical ferromagnetic member. The plurality of magnetic field members and the traverse magnetic field member are maintained out of contact with the cylindrical ferromagnetic member. Magnetic particles are placed on selected portions of the cylindrical ferromagnetic member. A time-varying composite longitudinal magnetic field and a time-varying traverse magnetic field are applied to the cylindrical magnetic member, while it is being rotated.

Abstract: A method and apparatus for determining the extent of defects in tubular elements for use in an oil or gas well is disclosed. The apparatus includes an electromagnetic or other suitable inspection device, cooperating with longitudinal and circumferential position detectors for determining the position and configuration of all defects within a tubular member. Signal generating means are provided for producing signals corresponding to the configuration, longitudinal position, and circumferential position of the defects located within the wall of the tubular member. The signals are processed, preferably by a computer, so that the presence, nature, and precise location of each defect is determined and visually displayed at a suitable display means. Display means are provided for generating a two-dimensional visual display wherein the circumferential and longitudinal positions of the defects are selectably displayed.

A saturating magnetic field and a fluctuating magnetic field are applied to the tubing and the magnitude of the induced fields and the changes are measured to quantify defects in the tubing.

Abstract: A method and apparatus for determining the extent of defects in ferromagnetic tubular elements comprising a continuous string for use in an oil or gas well is disclosed. The tubing trip tool measures tubing average wall thickness, local defects, such as corrosion pitting, and axial defects, such as sucker rod wear during removal of the tubing from the well. Tubing velocity is also measured, and couplings between tubing sections are detected and counted, in order to specify the axial location of defects on each tube, and also provide a profile of the condition of the overall string. A saturating magnetic field and a fluctuating magnetic field are applied to the tubing and the magnitude of the induced fields and the changes are measured to quantify defects in the tubing.

Abstract: A tubing trip tool for use in determining the extent of defects in tubular elements comprising a continuous string used in a subterranean oil or gas well during removal of the string from the well is disclosed. Local defects and axially extending defects, as well as the average wall thickness of the tubular elements, are measured. The position of the defects is determined by measuring the variable velocity of the tubular elements as they are removed from the well and by detecting end couplings having a larger cross-sectional area and the direction in which the end couplings are moving. A string profile of the position of the defects in the continuous string can also be established.

The tubing trip tool measures tubing average wall thickness, local defects, and axial defects, such as sucker rod wear during removal of the tubing from the well. Tubing velocity is also measured. A saturating magnetic field and a fluctuating magnetic field are applied to the tubing. Signals corresponding to changes in the induced fields are divided into channels for complete circumferential coverage. Phase shift is then determined by a zero crossing technique to quantify axial defects, such as sucker rod wear.
