World’s first multipoint hydrogen flux corrosion monitor.
For easy reliable measurement of flux in extreme environments.
Since year 2000, Hydrosteel® has been recognised as the simplest and most effective way to monitor hydrogen flux through steel in petrochemical service. Hydrosteel works by the magnetic attachment of a flexible metal plate onto a pipe or vessel. Air is drawn between the plate underside and adjoining steel surface, capturing hydrogen flux exiting the steel. The sample stream is passed over a hydrogen sensor. From the sample gas flow, capture surface area, and increased hydrogen gas concentration in the air, the hydrogen flux is calculated and displayed.
…just got better
Hydrosteel 6500 delivers the simplicity of measurement of the original handheld tool, with months of battery operated monitoring capability. Four separate sample lines ensure complete confidence in measurement integrity, so that the flux signature of a corrosion scenario is fully evident, and measures to mitigate corrosion are completely realised. The new Hydrosteel comes a new probe featuring more reliable attachment and wider temperature tolerance.
Flux measurement uniquely measures an active effect of corrosion of service steel. Unlike wall loss measurements, the sensitivity of flux measurement is not limited in sensitivity by measurement of small changes in thickness. Unlike corrosion coupons, it indicates corrosion of the actual service steel, not a steel specimen.
At low temperatures, the flux is generated by corrosion involving hydrogen promoters such as sour gas and HF. Flux provides a real time indication of active sour corrosion and the risk of hydrogen induced cracking (HIC) caused by such corrosion.
At elevated temperatures, flux is associated with naphthenic acid corrosion. Flux monitoring is also used to confirm the completion of hydrogen bakeouts.
