Abstract: Apparatus, systems, and methods for pipeline condition assessment using phased array ultrasonic transducers are disclosed. A sensing module for assessing pipeline condition comprises a body; and one or more phased array ultrasonic transducers (PAUTs) assembled on the surface of the body, each PAUT configured to emit multi-channel ultrasonic waves for scanning a pipe wall.

Abstract: A device for assessing the condition of a pipeline containing a liquid is provided. The device includes an actuatable maneuvering module to generate a force sufficient to move the device from one side to another side along a horizontal plane and to move the device from top to bottom along a vertical plane, or any combinations thereof, so as to maneuver the device.

Abstract: There is provided a pipeline inspection apparatus and an ultrasonic module for use in a pipeline inspection apparatus, the module comprising: ultrasonic transducers configured to assess the condition of a pipeline; and an elongate body including a front end and a rear end opposed to the front end, the body configured to mount the ultrasonic transducers around the circumference of the elongate body aligned along adjacent transverse planes wherein the ultrasonic transducers aligned along one transverse plane are rotationally offset from the ultrasonic transducers aligned along an adjacent transverse plane.

Abstract: A clamp comprising: a first arcuate portion; a second arcuate portion hingedly connected to the first arcuate portion; and a ratchet mechanism for locking the first and second arcuate portions in a closed position; wherein the ratchet mechanism comprises a linear rack provided with the second arcuate portion and a pawl provided with the first arcuate portion for receiving the linear rack; wherein the linear rack comprises one or more asymmetrical teeth and the pawl comprises a finger which is configured to engage with the teeth of the linear rack. The pawl is formed by a module which is detachably connected to the first arcuate portion.

Abstract: Apparatus and device for testing within a metal pipe are described. The apparatus includes an exciter for generating an electromagnetic (EM) field for exciting a wall of the metal pipe; an extendable and retractable sensor assembly comprising a plurality of sensor bars arranged in an angled manner with respect to an axis of the pipe for sensing residue EM field on a wall of the pipe; a plurality of guide wheel assemblies for supporting and moving the apparatus along the axis of the pipe; and a control unit for recording sensed data from the sensor assembly.

Abstract: A clamp comprising: a first arcuate portion; a second arcuate portion hingedly connected to the first arcuate portion; and a ratchet mechanism for locking the first and second arcuate portions in a closed position; wherein the ratchet mechanism comprises a linear rack provided with the second arcuate portion and a pawl provided with the first arcuate portion for receiving the linear rack; wherein the linear rack comprises one or more asymmetrical teeth; wherein the pawl comprises a plurality of fingers which are biased into engagement with the teeth of the linear rack.

Abstract: A clamp comprises a first arcuate portion, a second arcuate portion connected to the first arcuate portion via a hinge, and a ratchet mechanism for locking the first and second arcuate portions in a closed position. The first and second arcuate portions each comprise a circumferential groove which tapers in a radial direction from an opening of the groove to a base of the groove. The groove of one of the first and second arcuate portions has an angular extent which exceeds 180 degrees and has an opening with a width which is narrower at opposing ends of the groove than at a position partway between the ends.

Abstract: A tamper-evident cover for a component, the component comprising: first and second portions; and an actuator mechanism for moving the first and second portions or allowing the first and second portions to move relative to one another; wherein the cover comprises: a cover portion defining a cavity configured to receive the actuator mechanism of the component so as to prevent access to the actuator mechanism from the exterior of the cover portion; and a retention barb connected to the cover portion and housed within the cavity formed by the cover portion such that it is inaccessible from the exterior of the cover portion, the retention barb being configured to engage with the component so as to retain the cover portion over the actuator mechanism.

Abstract: A clamp 2 comprising: a first arcuate portion 4a; a second arcuate portion 4b connected to the first arcuate portion via a hinge; and a ratchet mechanism for locking the first and second arcuate portions in a closed position; wherein the first and second arcuate portions each comprise a circumferential groove 16a, 16b which tapers in a radial direction from an opening of the groove to a base of the groove; wherein the groove of one of the first and second arcuate portions 4a, 4b has an angular extent which exceeds 180 degrees and has an opening with a width w1, w2, w3 which is narrower at opposing ends of the groove than at a position partway between the ends.

Abstract: Defects in a pipeline may be detected by an in-line inspection tool passing therethrough. However, as the tool travels through the pipeline, errors associated with certain onboard components may accumulate. These errors may reduce the accuracy with which the locations of detected defects can be determined. Accordingly, markers may be positioned at various locations along the pipeline. Each marker may include a radio receiver to receive signal transmitted by an in-line tool passing thereby and one or more magnetic flux detection systems that may detect a magnetic field emanating from the in-line tool. The radio receiver may include an antenna comprising two or more coils connected in series and positioned side-by-side. The flux detection system may include one or more flux concentrators to amplify the strength of the magnetic field.
