EZ Zone® Tape

PURGE GAS RETAINING TAPE

FOR CLEAN CONTAMINANT-FREE WELDING

US & FOREIGN PATENTS PENDING

EZ Zone® tape is the perfect, innovative solution for preventing weld seam contamination by sealing the root gap between two pipes and retaining the argon gas. The tape consists of two adhesive-coated aluminum strips on the outer edges and an adhesive-free area in the middle.

Due to its unique construction, the edges of the aluminum tape adhere to both sides of the root gap of stainless steel and aluminum pipes, while the adhesive-free area is placed directly over the gap. The adhesive never comes into contact with the weld area during welding, resulting in a clean, contamination-free weld seam.

The EZ Zone adhesive tape is free of halogens and fluorocarbons, and consists of aluminum foil with a thickness of 74 micrometers, which adapts optimally to irregular surfaces and is heat-resistant up to 260 °C.

With the EZ Zone tape, the welder can effectively prevent contamination in the weld pool and thus produce more defect-free welds. This advantage made the adhesive tape the standard in the atomic energy sector, the chemical industry, in conventional power plants and in aviation within a very short time.


EZ Zone Tape innovatively offers the perfect solution for preventing weld contamination when sealing the root gap between pipes to retain Argon gas. The welding tape is comprised of two adhesive coated aluminum strips on the outside edges, with an adhesive-free center “Zone.”

Features and Benefits

Contaminant Free Weld

  • EZ Zone Tape eliminates the worry of adhesive contaminating the weld area when sealing  the root gap between pipes because it is composed  of two outside adhesive sections, separated by an adhesive-free center “zone”
  • Only the adhesive-free “zone” is placed over the weld, therefore the adhesive never comes in contact with the pipe as it is welded; creating a clean, contaminant-free weld
  • The “Zone” acts as a centering guide, making correct placement of tape and ensuring no adhesive contamination
  • Reduces pipe clean-up time and avoids costly x-rays

Flexible & Heat Resistant

  • Malleable aluminum tape easily conform to a number of complex shapes and uneven surfaces including stainless steel and aluminum pipes
  • Pressure-sensitive adhesive makes for easy application
  • Adhesive portion of aluminum tape withstands temperatures up to 500°F (260°C)
  • Aluminum foil portion of tape withstands temperatures up to 1100°F (593°C)

High Quality and Safe Components

  • EZ Zone Tape is free of halogens including  fluoride, chloride and bromide as well as chlorofluorocarbon, increasingly important in today’s highly regulated safety environment

How EZ Zone Tape Works

Clean
  • Clean the weld area of all contaminants
Align
  • Line up adhesive – free section of EZ Zone Tape over the root gap
  • Adhesive sections of the EZ Zone Tape should be secured on each side of the root gap of the adjoining pipes
Introduce Gas
  • Insert purge gas needle into root gap, ensuring connection to gas line
  • Introduce noble gas, evacuating oxygen
  • Commence welding when desired PPM level is achieved

Contaminate Free Weld

EZ Zone Tape offers the perfect solution for preventing weld contamination.  The welding tape is composed of two aluminum adhesive areas on the outside edges, with an adhesive-free center “Zone”. The unique design of the aluminum welding tape allows the edges to stick to the area surrounding the root gap on stainless steel and aluminum pipes with the adhesive-free “zone” being placed over the weld. The adhesive portion of the tape never comes in contact with the pipe as it is welded, creating a clean, contaminant-free weld.

Pre-heat temperature

The maximum pre-heat temperature of EZ Zone Tape is 500°F (260°C). Please note if applying EZ Zone Tape after the pre-heat temperature is achieved, the adhesive will not bond to the metal surface. In addition, if you apply the EZ Zone Tape before the pre-heat temperature is achieved, the adhesive will “cure” or thermoset to the metal surface and may become difficult to remove.

Minimum Application Temperature

The minimum application temperature for EZ Zone Tape is 10°F (-12.5°C).

Safe Components

EZ Zone Tape is halogen and fluorocarbon-free, creating a safe work environment.

Common Uses

EZ Zone welding tape has become a standard in the nuclear, chemical power plant, aerospace, and many other advanced welding industries.
