The oil and gas industry employs long distance pipelines to simplify the transport logistic and to reduce the final costs of petroleum derivatives. For the construction of pipelines, nowadays it is usual the application of pipes which are manufacture

Engineering applications for precision cylindrical parts have required increasingly tight geometric tolerances to guarantee their correct functionality. In addition to demanding better machine tools and manufacturing processes, it is also important t

Pipes are basic elements used in the construction of pipelines for the long-distance transportation of oil and gas and their derivatives. They can be manufactured by cold forming processes such as UOE and ERW, both widely used in the oil and gas indu

Mechanical vibrations, air and thermal instabilities are among the most disturbing agents that make difficult or impossible a successful speckle interferometry measurement in harsh environments. Usually, they destroy the interference signal or, at le

Pipelines are usually designed to withstand stresses generated by the internal pressure of the fluid being transported. Nonetheless, internal pressure is only one stress component of the real complex state of stresses acting on their walls. Usually,

The authors developed a portable optical residual stresses measurement device that combines the incremental hole-drilling method with digital speckle pattern interferometry working in polar coordinates. The device is able to measure radial in-plane d

Piezoelectric translators (PZTs) are very often used as phase shifters in interferometry. However, they typically present a non-linear behavior and strong hysteresis. The use of an additional resistive or capacitive sensor make possible to linearize

This paper describes and discusses a novel approach that uses artificial neural networks (ANN) to extend the measurement range of fiber Bragg gratings (FBGs) interrogators based on fixed narrowband filter demodulation. Interrogators with fixed spectr

The authors developed an achromatic speckle pattern interferometer able to measure in-plane displacements in polar coordinates. It has been used to measure combined stresses resulting from the superposition of mechanical loading and residual stresses
