A vast network of pipelines transports large volumes of energy products over long distances from production wells to processing and consumption sites. The pipeline industry relies on nondestructive testing (NDT) methods to detect and characterize the degradation and damage. To quickly and economically survey the large portions of the infrastructure, autonomous in-line inspection tools, commonly referred to as pigs, examine the pipe from the inside as they are propelled by the product flow…

Development of speed control algorithm for Instrumented Pipeline Inspection Gauge (IPIG) in high speed liquid petroleum pipelines

A prototype dynamic speed control mechanism is developed and integrated into an existing IPIG tool and tested in IOCL R&D Centre, Faridabad, where it has successfully negotiated speed excursions with necessary control actions.

Pipeline long-range inspection and monitoring by an innovative magnetic collar for magnetostrictive guided-wave systems

In this paper, a new system for pipeline long-range inspectio n and monitoring is described. The system is based on a set of local magnetostrictive sensors surrou nding the inspected pipeline. The

Ultrasonic immersion testing for crack detection and depth sizing in large diameter pipes

Detection and sizing of surface breaking defects in pipelines is of vital importance in the petrochemical industry. The work presented focuses on in-service inspections of large diameter (above 24′′)

A Review of the Real-Time Monitoring of Fluid-Properties in Tubular Architectures for Industrial Applications

An overview of the real-time monitoring of fluid properties in tubular systems for industrial applications, particularly for pipe monitoring sensors, viscosity, and flow measurements is presented and the different available sensing mechanisms and their advantages, drawbacks, and potentials are discussed.

Enhancement of eddy current testing probe for crack detection and lift-off compensation

Pipelines are subject to defect and corrosion which in turn can cause leakage and environmental damage. Eddy current testing has proved to be an effective technique to detect defects occurring in the

Physic perspective fusion of electromagnetic acoustic transducer and pulsed eddy current testing in non-destructive testing system

A novel physic perspective fusion NDT method of electromagnetic acoustic transducer (EMAT) and pulsed Eddy current testing (PECT) for detecting hybrid defects using a transceiver-integrated fusion sensor structure that can simultaneously excite ultrasound and pulsing eddy current.

Entropy filter for anomaly detection with eddy current remote field sensors

An entropy filter built on a-posteriori probability density functions associated with data series is considered in order to enhance signal peaks that potentially identify anomalies.

Rényi Entropy Filter for Anomaly Detection With Eddy Current Remote Field Sensors

An entropy filter is proposed that maps raw sensory data points into a local entropy measure and classified by means of a thresholding procedure based on the Neyman-Pearson criterion to enhance features that potentially identify defects.
