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.
Claims20
A sensing module for assessing pipeline condition, comprising:
- a body;
- and
- one or more phased array ultrasonic transducers (PAUTs) assembled on a surface of the body, each PAUT configured to emit multi-channel ultrasonic waves for scanning a pipe wall, wherein at least one of the one or more PAUTs comprises:
- a matching layer;
- a backing layer;
- a sensor placed between the matching layer and the backing layer for generating the multi-channel ultrasonic waves;
- and
- a housing that receives the matching layer, the backing layer and the sensor therein such that the matching layer does not extend on an outside surface of the housing.

A sensing module for assessing pipeline condition, comprising:
- a plurality of pre-loaded spring arms;
- and
- a transducer mounted at an end of each of the plurality of pre-loaded spring arms that deploy in a fully open position when the sensing module is centered in a pipe, wherein each transducer is configured emit an ultrasonic wave for scanning a pipe wall of the pipe, and wherein a first ultrasonic wave emitted from a first transducer is configured to overlap at least a portion of a second ultrasonic wave emitted from an adjacent second transducer.
A device for assessing pipeline condition, comprising:
- a sensing module for assessing pipeline condition, comprising:
- a body;
- and
- one or more phased array ultrasonic transducers (PAUTs) assembled on a surface of the body, each PAUT configured to emit multi-channel ultrasonic waves for scanning a pipe wall;
- one or more battery modules for powering the sensing module;
- and
- one or more sets of supporting structure for maintaining the sensing module at a center of the pipe, wherein at least one of the one or more PAUTs comprises:
- a matching layer;
- a backing layer;
- a sensor placed between the matching layer and the backing layer for generating the multi-channel ultrasonic waves;
- and
- a housing that receives the matching layer, the backing layer and the sensor therein such that the matching layer does not extend on an outside surface of the housing.
