Hydrogen detection tape DX-2106H from Nitto allows for the visual detection of hydrogen gas leaks by permanently changing colour when in contact with hydrogen gas. Tape visually changes colour, from amber to black, in as little as 10 seconds when exposed to H2 (depending on the flow rate, temperature, time and percentage of hydrogen).
The Nitto tape can detect hydrogen leaks that contain as little as 1% H2 concentration and will not return to its original colour once exposed to hydrogen gas.
The product is said to be easy to use, applies the same as a typical silicone /polyimide PSA, and can be used in most indoor or outdoor environments.
Less influenced by wind, position, duration, and skills, the company says, it can be easily applied to or wrapped around pipes, flanges, fittings, valves, and access panels.
The permanent colour-change identifies the leak location even if the H2 line is shutoff. Applications include and are not limited to power and chemical plants, transportation markets, hydrogen co-generators, fuel stations, storage tanks, and compressors.
