Hydrosteel - fast, reliable hydrogen flux spot measurements Hydrosteel 6000 is the ultimate portable tool for monitoring active sour, HF and high temperature corrosion and active risk of diffusive hydrogen damage to steel. Hydrosteel measurements of hydrogen flux are used to identify the time and location of these corrosion scenarios. Data is used to confirm effective process control and inhibitor control of corrosion, aiding decisions relating to feedstock blending, service life, cost-effective corrosion control programmes, production downtime and plant safety. Hydrosteel 6000 is completely non-intrusive and intrinsically safe for use in flammable areas. Only minimal test surface preparation is required, and no consumables such as greases are needed, enabling reliable measurements to be made within 60 seconds.
How Hydrosteel works
Measurements can be taken at temperatures up to 500°C, 930 °F allowing high temperature active corrosion to be swiftly detected and monitored. Probes can be applied to pipes as small as 3.5 inches diameter to large vessels and flat surfaces, and at any orientations (see below).
Figure 1
A flexible Hydrosteel ‘collector plate’ is attached to a steel pipe or vessel magnetically, or with strapping as shown in the schematic above. Hydrogen gas fluxing from the steel surface under the collector plate, is entrained in an air stream to a highly sensitive hydrogen analyser where the concentration of hydrogen in the air stream is registered. Because hydrogen in air is highly diffusible the background hydrogen level is usually low and stable, and enrichment in hydrogen concentration bought about by the collection of flux provides a dependable way of measuring.
Hydrosteel 6000 flux measurement data is supported by conversion charts which enable active crack risk and corrosion rates to be estimated, as shown below for high temperature corrosion.

Hydrosteel probes LT-R Probe The LT-R probe is a low temperature, roaming probe 6 inches in diameter, enabling spot measurements of flux within 60 seconds. It attaches to the steel magnetically, and with the aid of a strap for smaller pipes. The probe can be attached to steel surfaces as small as 3.5 inches in diameter and at temperatures up to 130°C, 270°F. Each collector plate can be used for up to 500 individual spot measurements. Extension poles are also supplied for use with the LT-R to provide extended reach on pipe trains. Applications of the LT-R include identifying the time and location of corrosion hotspots. Probe readings are used to verify the causes and control of corrosion, either by undertaking frequent measurements, or using the 36 hr monitoring capability of the instrument. HT-R Probe The high temperature HT-R probe is 2.25 inches in diameter and magnetically attachable to the steel surface. It can be applied to any steel surface greater than 8 inches in diameter and at temperatures up to 500 °C, 930 °F. Each replaceable probe plate can be used for up to 150 individual spot measurements. The HT-R probe has been specifically designed for insertion into inspection ports and is optimised for initial hydrogen flux inspection and mapping surveys of high temperature acid corrosion caused by naphthenic acid and thiols.
HT-S Probe
The high temperature stationary HT-S probe is 2.25 inches in diameter and is attached with banding to steel surfaces. The probe’s small diameter enables measurements at pipe bends where corrosion can be significant. Again, this probe is designed for semi-permanent installation allowing repeat monitoring at a particular site of concern. The HT-S probe can be attached to any steel surface greater than 3.5 inches in diameter and up to 500°C, 930°F. They are used in routine surveys of sour, HF and naphthenic acid corrosion, in particular with a view of routinely assessing the corrosivity of crude blends at high criticality sites in refinery units. It is also used in hydrogen bakeouts. Hydrosteel 6000
AT-S Probe The all temperature stationary AT-S probe is 6 inches in diameter. It has been designed for semi-permanent installation at a site and is attached to a steel surface using banding. The AT-S probe is ideally attached at a site that requires frequent monitoring, ensuring consistent measurements time and again. These probes can be fixed to any steel surface greater than 8 inches in diameter and at temperatures up to 500°C, 930°F.
The Hydrosteel Complete Kit includes both the low temperature and high temperature probes, giving you everything you need to begin monitoring active corrosion.

Waarom een kalibratiecertificaat? .................................................................................................. Een kalibratiecertificaat vermeldt hoeveel een meetinstrument afwijkt ten opzichte van onze, naar (inter)nationale standaarden herleidbare, kalibratiemiddelen. Bij de meetresultaten op het certificaat wordt tevens vermeld of het meetinstrument voldoet aan de specificaties die door de fabrikant zijn opgegeven. Zonder kalibratiecertificaat kunt u er vanuit gaan dat de meter voldoet aan de fabrieksspecificaties, maar aantonen kunt u dit niet. Een testcertificaat van de fabrikant is te beknopt om de lineairiteit aan te tonen en is niet geregistreerd op naam (wat wel degelijk een vereiste is).

RvA accreditatie ............................................................................................................................ Het kalibratielaboratorium van EURO-INDEX beschikt sinds 21 augustus 1997 over een RvA accreditatie naar NEN-EN-ISO/IEC 17025. Deze accreditatie geldt voor verschillende grootheden, zoals gespecificeerd in de scope bij accreditatienummer K105 op www.rva.nl. Test- en meetinstrumenten voor grootheden die deel uitmaken van de gespecificeerde scope, kunnen worden voorzien van een RvA kalibratiecertificaat. De metingen worden uitgevoerd met standaarden waarvan de herleidbaarheid naar (inter)nationale standaarden, ten overstaan van de Raad voor Accreditatie, is aangetoond. In het Multilateral Agreement zijn de meeste Europese landen overeengekomen elkaars accreditaties te accepteren. Hierdoor is een RvA kalibratiecertificaat internationaal geaccepteerd. Bovendien wordt op een RvA kalibratiecertificaat de meetonzekerheid van de gerapporteerde meetresultaten vermeld. Verhuur van meetinstrumenten ........................................................................................................... EURO-INDEX biedt een assortiment meetinstrumenten te huur aan. Na deskundig advies van onze productspecialisten, wordt bepaald welk instrument u nodig heeft voor uw specifieke werkzaamheden. De instrumenten worden compleet met accessoires geleverd, inclusief herleidbaar kalibratiecertificaat. Wijzigingen voorbehouden EURO-INDEX® NL 13002
