DetecTape™ H2 | 10 mil - PF4 | Hydrogen Leak Detection

Main features

Self fusing
Suitable for all metal substrates
Perforation every 4 inches

Product Description

DetecTape™ H2 DT-H210015-PF4 is a passive colorimetric (color changing) self-fusing silicone tape designed to detect hydrogen gas (H2) leaks in fuel cell, transmission, storage, and generation facilities. When in contact with concentrated hydrogen gas, the tape color changes from light gray to dark black in the event of a leak due to damage or seal failure.

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 DT-H210015-PF4 is perforated every 4 inches (10 cm) and can be used for up to 40 applications. It covers up to 40 detection points on 1/4in (6mm) average diameter pipelines or fittings.
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.

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.

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.
