Orders take 2 to 3 business days to process and then ship via FedEx. Shipping times are determined by your selected shipping method (options include: ground, 2 day, overnight, etc.). International orders take longer. However, due to the COVID-19 pandemic, there may be additional delays.
The speed of the color change depends on the concentration of hydrogen, flow rate and temperature. For example, a 100% hydrogen concentration at 6ml/min flow rate at room temperature will have a color change in under a minute. The speed of the color change may decrease if the tape has been applied in an outdoor or hot environment for an extended period.
The hydrogen detection tape should be stored between 50°F-80°F (10°C-27°C), at 25-50% relative humidity, and out of direct sunlight.
We recommend replacing the hydrogen detection tape every six months from date of installation.
After 6 months, the tape may become less sensitive to hydrogen gas which may result in slower color change. The tape may also become fragile and hard to remove, especially in outdoor applications.
The hydrogen detection tape may change color in the presence of hydrogen sulfide (H2S) and/or carbon monoxide (CO) at above 100°C.
If hydrogen gas is present, the color will change. However, at ambient conditions if the hydrogen is diluted with other gases such as carbon monoxide (CO), hydrogen sulfide (H2S), or nitric oxide (NO) the color change will be slower. Not all gases have been tested. Please contact us for more information.
We do not recommend using this product for hydrogen sulfide. Hydrogen detection tape can change color in the presence of hydrogen sulfide, but only at temperatures higher than 212°F (100°C). No color change has been observed at room temperature with 500ppm of H2S.
No, the amber color comes from the polyimide backing which is used to protect against UV light and the color-change to black is this product’s specific characteristic.
Yes, hydrogen detection tape has been tested in high humidity, and in high/low temperature chambers. Additionally, 18-month field trials have been conducted in all seasons including sunshine, rain, and snow.
It may be more difficult to remove the tape in regions with higher humidity and temperature. If residue is left behind, it can be removed with a solvent (i.e. alcohol, etc.).
Yes, this tape can be applied to surfaces up to 212°F (100°C). At higher temperatures, the longevity of the tape may be reduced depending on the temperature.
Yes, hydrogen detection tape can be used in in temperatures as low as -40° F (-40° C). At lower temperatures, the observable color change may be slower.
The hydrogen detection tape will change color with leaks that contain as little as 1% hydrogen. Lower levels of hydrogen will require more time for observable color change. Color change speed also depends on flow rate and temperature.
Hydrogen detection tape can be applied at hydrogen storage locations, including transfer pipes with threaded joints, hydrogen dryers, etc.
No, this tape was developed to detect exact leak locations on pipelines, vessels, etc. This tape should not replace an area sensor and should be used as part of a comprehensive leak detection system. Please refer to the manual for further application explanations.
No, this tape does not stop gas leaks. It is meant to be a proactive approach to detecting potential leaks.
