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.” It allows a welder to effectively prevent contamination in the weld joint and increase the number of pure finished welds. That is why EZ Zone has become the ideal standard within the nuclear, chemical, power plant, and aerospace industries. For more info on other welding consumables: http://www.aquasolwelding.com/

2. About
• The Opti-Purge Inflatable Purging System increases productivity when welding large
diameter pipes 48″ to 84″ (1219 mm to 2133 mm) of various materials including stainless
steel, titanium, nickel and several other metals and alloys.
• The unique one-piece design of Opti-Purge consists of two outer rings and a hollow
connector. The unit is easily and quickly inflated to create an impermeable seal within the
pipe wall. The hollow connector dramatically reduces the amount of inert gas needed to
purge the weld zone, saving both time and money. The exterior of the hollow connector
consists of high heat resistant material that can be exposed to temperatures up to 1004°F
(540°C).

3. • A reflective strip on the hollow connector conveniently indicates the center of the Opti-Purge,
allowing for fast and accurate alignment of the system.
• The Opti-Purge is the ideal solution for welding large pipe rapidly, requiring minimal
preparation for maximum results.

4. Features and Benefits
Inflatable Structure
• Flexible, lightweight structure
• Inflated rings create an impermeable, air tight seal on pipe wall
• Re-usable, long-lasting solution for purging multiple pipes of the same
diameter
High Heat Resistant Hollow Connector
• High heat resistant, durable exterior fabric can be exposed to temperatures
up to 1004°F (540°C) to accommodate heat affected zone (HAZ)
• Supportive rods extend down length of hollow connector to maintain
structural integrity
• Complete with luminescent indicator for accurate alignment with root gap

5. Proprietary Relief Valve
•Factory pre-set relief valves allow for precise flow rates while minimizing set-up time and reducing
gas consumption
•Aids in maintenance of optimum seal on pipe wall
•Prevents risk of over inflation
Tri-Flow Inner Tubing System (BLUE, BLACK & WHITE Hoses)
Multiple inlet/exhaust ports for faster, more efficient purging
Separate Connections:
BLUE – Inflation of unit
Initial function is to inflate the unit by allowing gas to flow into the internal tubing system. Then it
proceeds to flood the weld zone with noble gas.
BLACK – Increase Gas Distribution Within Weld Zone
Designed to expedite purging, the secondary (BLACK) purge hose is used to flood the weld zone
with inert gas and evacuate oxygen at a faster rate.

6. WHITE – Exhaust Connection
Connect this hose to an Oxygen Monitor, such as Aquasol’s PRO OX®-100 that obtains readings down
to 100 PPM (0.01%), for continuous or spot monitoring of oxygen in the weld zone
Pull Loops
Strong pull loops can be connected to a rope or chain to insert or remove the Opti-Purge
Moderate tension should be applied on pull-wires to prevent sagging of the harness during
installation and operation

7. How Opti-Purge Works
1. Using the pull loops, position Opti-Purge in the pipe so that the reflective, glow tape portion in the center of
the unit is aligned with the root gap
2. Connect inert gas lines to the BLUE and BLACK hoses
BLUE gas hose is required to inflate the purge bladders
BLACK gas hose is optional to expedite the purging process
3. Turn the gas supply on to inflate the unit and purge the weld zone
Recommended Flow Rate for Purging:
150 CFH (70 LPM)
4. Once a tight seal has been achieved, commence welding while maintaining flow rate
5. After the weld is complete, turn off the gas supply to deflate the unit. Once the
heat zone has sufficiently cooled, remove Opti-Purge from the pipe. Be sure to disconnect
all gas lines and monitoring equipment.
6. Clean Opti-Purge and store in area away from hazardous and sharp objects
