摘要： Methods and systems for determining information about an object are described. In one aspect, a method includes illuminating an object with a plurality of lines of light, the lines being spaced-apart along an axis, and acquiring a sequence of images of the lines of light while rotating the object about the axis. The method further includes, for each image, determining a location of an extremum for each of the lines of light. Furthermore, the method includes establishing a reference line based on the location of the extrema for a first plurality of the lines, calculating a deviation between the extrema of a second plurality of the lines and the reference line, and determining information about the shape of the object based on the calculated deviations.

摘要： Embodiments of the present disclosure are directed to methods of manufacturing steel tubes that can be used for mining exploration, and rods made by the same. Embodiments of the methods include a quenching of steel tubes from an austenitic temperature prior to a cold drawing, thereby increasing mechanical properties within the steel tube, such as yield strength, impact toughness, hardness, and abrasion resistance. Embodiments of the methods reduce the manufacturing step of quenching and tempering ends of a steel tube to compensate for wall thinning during threading operations. Embodiments of the methods also tighten dimensional tolerances and reduce residual stresses within steel tubes.

摘要： Thread parameters for a threaded object are determined. Spatial reference systems (X, Y, Z) and (X′, Y′, Z′) are respectively identified for a position sensor and the threaded object. A transformation matrix describing a quadratic form representing the threaded object in (X, Y, Z) may be determined to relate the reference systems. For example, a sensor trajectory on the threaded object may be determined, along with measurement points on the threaded object. The measurement points may be selected so the matrix, evaluated on these values, has maximum rank. Position data at measurement points in the second reference system may be transformed into the first reference system, yielding first results. After coating the threaded object, position data at the measurement points may be acquired again and transformed into the first reference system, yielding second results. Comparisons between the first and second results may provide thickness of the coating and quality verification.

摘要： A method for producing a tubular bar, more particularly a stabilizer bar, is provided. The method comprises providing a tubular bar of desired size having an outer and inner surface, heating the bar to an elevated temperature, quenching the bar by application of a cooling fluid to the surfaces of the bar, and forming the tube to a desired shape without annealing. The method further provides for the composition of a high-strength, high formability carbon steel alloy to be used in conjunction with the method. Advantageously, the bar is formable without thermal processing subsequent to quenching. In this fashion, metal tubular bars, such as stabilizer bars, may be formed at reduced cost.

摘要： Equipment for oil and/or gas drilling, completion, storage and transportation, including pressure vessels, tools, pipes, tubes, connections and any other parts is coated with highly structured composite material. Due to its highly structured composition it is a particularly effective barrier to protect metals against attack by corrosive substances such as hydrogen sulfide, carbon dioxide and sea water, if necessary under hydrothermal conditions. At the same time it is also abrasion stable, for example against a grinding effect by sand, as well as resistant to the impact of mechanical load e.g. by tools. This is achieved by a coating comprising a binder comprising at least one cross-linked resin, wherein the resin comprises at least one of polar group; at least one type of hydrophilic flakes with an aspect ratio of more than 10, wherein the surface of the flakes at least partially comprises a metal oxide.
