Non-Standard Robots for NDT of Pipe Welds
2018 19th International Carpathian Control Conference (ICCC), 2018Non Destructive Testing (NDT) is a field where the standard architecture of the robots (such as common industrial robots) may be hardly applicable. That fact stems from necessity to ensure not only high accuracy, repeatability and dexterity but especially appropriate robot architecture (joints, links and actuation systems layout) for minimizing the ...

NDT Inspection Mobile Robot With Spiral Driven Mechanism in Pipes
IEEE ISR 2013, 2013This paper describes an NDT inspection mobile robot to drive 100m away with inspection module in 10cm pipes. A spiral driven mechanism was adopted to obtain a high traction force. The inspection module was made with a camera and four laser sensors. This module can find out 1mm size defects with a laser image sensor and recognize damages of the pipes ...

On the Inspection of Glass Reinforced Epoxy Pipes Using Microwave NDT
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019Glass Reinforced Epoxy (GRE) pipes are rapidly replacing their steel counterparts in pipeline infrastructures owing to their inherent advantages like corrosion resistance, lightweight, and low maintenance costs. However, GRE pipes suffer from a variety of defects which occur during manufacturing or in-service.

Evaluation of Pits in GRP Composite Pipes by Thermal NDT Technique
Journal of Reinforced Plastics and Composites, 2011In recent years, pipeline operators face many threats to the integrity of pipelines and hence, sophisticated nondestructive testing (NDT) technologies and measuring devices are being used for diagnosing the pipeline conditions. The presence of various defects is almost common during manufacturing, handling and under servicing conditions of glass-fibre ...

The Problems Associated With NDT of High Pressure Flexible Pipes
Advances in Underwater Technology, Ocean Science and Offshore Engineering, 1990The variety of materials used in the manufacture of high pressure flexible pipes provides, in the first instance, an extensive range of possible NDT methods. However their complex, composite construction imposes equally extensive constraints on the operability and potential effectiveness of many of these methods.

Inspection of Non-Metallic Pipes Using Microwave Non-Destructive Testing (NDT)
2018 IEEE International RF and Microwave Conference (RFM), 2018Non-metallic components are increasingly finding application in numerous industries including oil and gas, energy, transportation, and construction. The inherent advantages of these components, which include corrosion resistance, light weight and high strength-to-weight ratio have attracted several industries to employ non-metallic components. However,

Creep Failure of a Steam Pipe Girth Weld and NDT Strategy on Creep Damage
Engineering Failure Analysis, 2019Abstract 12Cr1MoV is a commonly used heat-resistant steel for the steam pipelines of subcritical power boilers in China. Usually, the girth weld joints are the weakest areas of the entire steam pipelines. In this work, a leakage failure of girth weld joint in a 12Cr1MoV steam pipe with about 10 years' service was analyzed.

Applicability of Eddy Current Technique in In-Bore NDT Tool for ITER Hydraulic Pipe Welds
Fusion Engineering and Design, 2019Abstract Eddy current testing (ECT) is a potential candidate for non-destructive testing of pipe welds in fusion facilities because of its simple configuration and applicability in radiation environments. This paper provides an applicability assessment of the ECT method to detect weld defects in the ITER blanket module hydraulic pipes.
