LINQTAPE HDT1S | Hydrogen detection tape

Applications:

• Power and chemical plants.

• Transportation markets.

• Hydrogen Co-Generators.

• Fuel stations.

• Storage tanks and compressors.

• New energy markets and more.

Application Ideas:

• Easily applied to or wrapped around pipes, flanges, fittings, valves, access panels, etc., providing immediate identification of precise hydrogen leak locations.

• Permanent Color Indication: Identifies leak locations even if the hydrogen line is shut off.

What happens if these tapes are exposed to higher temperatures?

LINQTAPE HDT1S is a Polyimide tape with a Silicone adhesive that is reactive to Hydrogen. When it comes to materials, this is very similar to our PIT1S so the operating temperature is 260°C. The problem lies with the reactive nature of the tape. The higher the temperature, the lower the time it takes to detect H2. Since some Hydrogen applications are in the negative °C, we know that it will take much, much longer for the tape to react at cryo temperatures.

On the upper limit, we have tested it for 6 months at 60°C and it works fine. We don't know how the tape would react in higher temperatures though. Technically, the materials should be OK but the high temp will probably affect the reactivity and cause all kinds of issues. The entire idea with H2 detection tapes is really to prevent things such as jet fire from happening by regular monitoring. In theory, we expect the tape to react since H2 will be present and the temperature caused by the jet fire will accelerate the reaction. In practice, we don't know.

it is important to note that the tape WILL react even with a very low % of H2 in the air (even 1% will suffice). It will just take much longer (hours) than if there were higher concentrations where you would expect a color change within a couple of minutes.
