ASME Pressure Vessels and Piping (PVP2018) Conference – VibraTec to publish our technical developments

VibraTec will publish 3 papers at the PVP Conference in Prague next month. The articles will present an innovative method to model fluid-structure interaction in industrial piping, and also non-intrusive diagnosis.

Heavy fluid flow within industrial piping interacts with structure walls, applying an asymmetric, unsteady load. Vibrations provoked by this flow are an important phenomenon that is hard to model accurately. VibraTec is proud to present our innovative findings; a new simplified approach to modelling turbulent sources. Our progress in non-intrusive characterization of fluid loads will also be published.

Rémi SALANON and André BARAMILI will be on hand on the 17th and 18th of July to discuss your piping issues and answer questions.

More information available on the conference website.

Non-intrusive pipe pressure measurements – a dream come true !

VibraTec is proud to present results of our work in developing a non-intrusive method to measure pressure in pipes using PVDF (PolyVinlyDiene Fluoride) sensors.

Having developed a dedicated calibrator to determine the fluid / structure coupling coefficient, VibraTec is able to assess PVDF sensor sensitivity according to specific installation characteristics at each client site.

This method avoids problems linked to pressure taps that are not positioned conveniently for these measurements. It is accurate regarding phenomenon amplitude & frequency location.

The paper will be presented at OTC Asia 2018 in Kuala Lumpur from 20th to 23rd of March.

Fatigue Design 2017: Innovative numerical fatigue methodology for piping systems: qualifying Acoustic Induced Vibration (AIV)

Fatigue Design 2017 Conference in Senlis (France) from the 29th to the 30th of November will be the occasion for VibraTec to present its work on AIV fatigue methodology.

Acoustic Induced Vibration (AIV) refers to the high acoustic energy generated by pressure-reducing devices that excite pipe shell vibration modes, producing excessive dynamic stress. Analysis of this risk is an important part of Asset Integrity Management systems as AIV can cause catastrophic piping failure. Existing guidelines address this risk through an analytical assessment. However, these methodologies are limited.

The proposed approach for identifying AIV damage is based on a dynamic stress evaluation at pipe discontinuities (welded connections and supports). This evaluation is performed through a fluid-structure coupling Finite Element Analysis. Pressure fluctuations inside the pipe are predicted and coupled with a pipe structural analysis. This methodology is provided with its validation through measurement on an actual AIV field case, corresponding to a crack initiation due to AIV.

AIV – FIV: VibraTec’s your one-stop piping expert !

Piping vibration can lead to severe damage to main lines & auxiliary systems (small bore, thermowells etc.): vibration can induce cracks & leaks, leading to heavy maintenance and even installation shutdown. Proper understanding of the phenomena at stake is essential to prevent and mitigate these risks. VibraTec is a world-class expert that can help you keep your major piping vibration issues under control.

This year’s SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition in Jakarta (and not Bali as initally planned) from the 17th to the 19th of October will be the occasion for VibraTec Asia Pacific’s Hafiz KARIM to present two papers based on case studies respectively in AIV diagnosis & mitigation (a cracked FPSO flare network tail pipe), as well as in discontinuity-related FIV issues in pipe system design.

The perfect time to come learn more !

VibraTec’s R&D is in the pipeline !

Singularities in industrial pipelines (such as section or direction changes) are often responsible for vibrations caused by continuous internal flow. To understand and model the complex fluid source, VibraTec has been conducting innovative research combining experimental methods, instationary fluid mechanic computations and statistic tools applied to reduced-scale models.

We are proud to be sharing an overview of current results at the « Congrès Français de Mécanique » in Lille from August 28th through September 1st. 2 presentations – a great occasion to meet you and discuss these issues.

Using Particle Image Velocimetry to address piping FIV issues

VibraTec is reaching a new level of innovation in the study of Flow-Induced Vibrations in piping systems: we are the first to perform coupled vibration and fluid dynamics measurements in confined flow configurations, using advanced Particle Image Velocimetry (PIV) techniques. We are proud that our work on tackling the challenges of this coupled measurement campaign will be presented at the 12th International Symposium on Particle Image Velocimetry in Busan, South Korea from June 18th through 22nd.
