DetecTape™ H2 | 20 mil NP| Hydrogen Leak Detection


Main features
  • Self fusing 20 mil tape
  • Easy to install
  • No perforation

Product Description

DetecTape™ H2 DT-H22020018 is a passive colorimetric (color changing) self-fusing silicone tape designed to detect hydrogen gas (H2) leaks as low as 400ppm in fuel cell, transmission, storage and generation facilities. DetecTape changes from light gray to black when directly exposed to hydrogen gas. Inspectors and equipment operators can proactively wrap this new hydrogen leak indicator over nearly any connection and visually identify localized leaks during routine inspections. Identify leaks you never knew you had and improve safety in your facility today.

DetecTape™ H2 is self fusing so it does not leave adhesive residues and bonds to itself upon contact. It is chemically and UV resistant with an operating temperature ranging from -54ºC up to +232ºC

DetecTape™ H2 DT-H22020018 is not perforated and can be used for up to 20 applications. It covers up to 20 detection points on pipelines or fittings larger than 1/2 inch diameters.
Thickness Tolerance is +/- .002 in (+/- 0.05 mm)
Width Tolerance is +/- 0.125 in (+/- 3.175 mm)

DetecTape™ H2 can be used on hydrogen pipelines and other objects where tape can be wrapped around itself. Application examples include but are not limited to connections, fittings, valves, welded seams, joints, flanges, and areas susceptible to vibration damage. It is trusted by steel manufacturing plants, pharmaceutical science laboratories, oil and gas refineries, semiconductor fabrication plants, renewable research laboratories, power plants, fuel cell plants, hydrogen storage facilities, and hydrogen fueling stations

Hardness
Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.

Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Tear Resistance
Tear Resistance
Tear resistance (or tear strength) is a measure of how well a material can withstand the effects of tearing.
 85 psi
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
 4.82 MPa

Temperature Range -65 to 260 °C

Additional Information

Surface preparation recommendations

Inspect intended detection point and surrounding area for contaminants. Wipe area clean of debris or fluids.

Application instructions

STEP 1 Pull tape strip from roll up to perforation point.

STEP 2 Tear away tape strip from roll at perforation point and remove liner backing. Ensure blue guideline is facing outward for clear visibility.

STEP 3 Press tape strip firmly approximately 1 inch (2.5 cm) away from the intended detection point and begin the first wrap with one 100% complete overlap. TIP: Tightly stretching the tape around irregular contours can provide a cleaner presentation.

STEP 4 Continue stretching the tape strip while wrapping with a half overlap, using the blue guideline as half point, across desired area until approximately 1 inch (2.5 cm) past the intended detection point.

STEP 5 Finish the wrap by ending the remaining tape strip with a 100% complete final overlap. Press on wrap firmly.



Tape removal

Use a utility knife, blade or a scissor to easily remove tape from connection. Cut away tape and dispose of in a proper trash receptacle.
