Hydrosteel allows non-intrusive in situ measurement of hydrogen permeation through steel with no fuss… even steel surface cleaning is minimal and in many cases is not required at all. The equipment offers highly sensitive and quantitative measurement of hydrogen flux over a wide dynamic range, rapidly and reliably. It is totally simple to use, and includes an extension arm for accessing steel up to six feet distant. Hydrosteel can be engaged at different test sites at half minute intervals in search of hydrogen flux. Detailed measurements can be made at minute intervals, for example along a length of pipe. Once a representative site has been found the hydrogen flux can be monitored, using either the battery power source, for up to 40 hr, or an external power source, longer term.

Hydrosteel probes explained
|
LT-R probe
The LT-R probe is a low temperature, roaming probe enabling spot measurements of flux within 60 seconds. It attaches to the steel magnetically, and with the aid of a strap for small 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.

| HT-R Probe |
|
| HT-R probe
The high temperature HT-R probe is 2.25 inches in diameter and magnetically attachable to the steel surface. It has been specifically designed for insertion into inspection ports. It can be applied to any steel surface greater than 8 inches in diameter and at temperatures up to 500 °C (930 °F).
|
AT-S probe
The all temperature stationary probe has been designed for semi-permanent installation at a site and is attached using banding. The AT-S probe is ideally attached to sites requiring frequent monitoring, ensuring consistent measurements time and again. It can be fixed to any steel surface greater than 8 inches in diameter and at temperatures up to 500 °C, 930 °F.

| HT-S probe
The high temperature stationary probe is a 2.25 inch diameter probe which is attached with banding to steel surfaces. The probe allows measurements at pipe bends and other curved areas where corrosion can be significant. This probe can be semi-permanently attached to any steel surface greater than 3.5 inches in diameter and up to 500 °C, 930 °F.

Hydrosteel 7000 is a fixed, totally non-intrusive device for the continuous monitoring of hydrogen flux at high criticality sites within petrochemical and gas production and petrochemical refining operations.
Hydrogen flux measurement relates directly to active sour and HF corrosion at <100 °C, and any acid corrosion (e.g. sulfide/napthenic acid) at higher temperatures, and is designed for fixed monitoring on steel surfaces subject to these corrosion scenarios, such as in sour gas wells, lines, storage facilities and treatment plants, amine and alkylation units, distillation columns, outlets and heat exchangers (NAC), and cracking unit overheads.
Features include:
* Fixed for continuous flux measurement
* Operates without human interference
* Intrinsically safe (approvals pending)
* Water proof with an IP66 rating (pending) to protect from heavy and driven rainfall
* Designed to withstand some of the harshest environments in the world, operating in ambient temperatures between -20 and 55 °C (-4 to 131 °F), in dust storms, and in environments containing volatile organics, hydrogen and humidity.
* Can be applied to steel surface up to 500 °C
* Data-logs flux and steel temperature every ten minutes
Fixed corrosion monitor for the measurement of corrosion at high criticality sites:
* Corrosion control
* Feedstock blending
* HIC damage reduction and control
* Sour, HF acid, and all high temperature corrosion monitoring
* Risk based inspection of prospective hydrogen damage
