1. Aquasol® WATER SOLUBLE PAPER AND TAPE
DISSOLVABLE PURGE GAS BARRIER FOR TIG WELDING
MADE IN THE USA

2. Why Water Soluble Tapes?

3. Traditional purge systems present significant limitations as they are inefficient, costly, and labor-intensive. Additionally, conventional purge systems must be placed far from the weld zone (10-20 ft.) adding unnecessary inconvenience and costs to the welding process.
To overcome these limitations, Aquasol Water Soluble Paper and Tape were introduced. Together these components can be constructed by hand into unique purge dams. They are able to be placed within close proximity of the weld zone, thereby increasing efficiency of the entire welding process

4. About Water Soluble Paper & Tape
Aquasol Water Soluble Paper provides an excellent barrier used to retain noble gases such as argon and helium within the weld zone during TIG welding of stainless steel and aluminum pipes.
Comprised of sodium carboxyl methyl cellulose and wooden pulp, Aquasol Water Soluble Paper dissolves quickly and completely in most liquids, including water.  Its 100% bio-degradable composition leaves no residue behind in the pipeline.
Aquasol Water Soluble Paper is available in a wide range of grades and sizes permitting the construction of purge dams for any pipe diameter.
Extremely easy to store, non-toxic and environmentally friendly, Aquasol Water Soluble Paper is ideal for the nuclear, petrochemical, and food and beverage industries.

5. Features and Benefits

6. Low Air Permeable Purge Gas Barrier for Any Pipe Diameter
Creates excellent barrier for retaining noble gas
Simple and fast construction that can be customized to fit various pipe schedules and sizes
Saves money on gas consumption as paper can be placed in close proximity to the weld zone, thereby using less inert gas to displace oxygen in the purge chamber
Easily secures to inner pipe wall with use of Aquasol Water Soluble Tape, creating an air-tight seal
Biodegradable & Safe
Made of sodium carboxy methyl cellulose & wooden pulp
EPA and CE approved
100% biodegradable
Safe and accepted choice by nuclear, petrochemical, food and beverage industries

7. 3. Easy Removal
Dissolves effortlessly and rapidly during water or steam hydro-test
No residue remains in the pipeline
4. Convenient
Paper rolls are individually packaged for convenient storage and shipping
Available in a wide range of sizes, grades and forms permitting construction of any pipe diameter

8. How Does It Work?

9. Trace & Impress
Trace pipe’s inner diameter by pressing paper along pipe edge, creating an impression. Then fold to form a 90° angle.

10. 2. Cut
Cut in a circle around the impression, approximately one-third times greater than pipe diameter.

11. 3. Slit
Slit approximately 1″ to 2″ segments perpendicular to impression on paper making first slit at 12 o’clock position followed by 3 o’clock, 6 o’clock and so on.

12. 4. Position Inside Pipe & Tape In Place
Cut Aquasol Water Soluble Tape into pieces. Position slit Aquasol Water Soluble Paper dam inside pipe. Secure dam with tape pieces along the entire circumference.

13. 5. Activate Water Soluble Tape – Moisten Sponge
Moisten an ordinary sponge with water and squeeze out excess water until sponge is damp.

14. 6. Lightly Dab
Lightly dab sponge along the water soluble tape portion of the dam. The dampened sponge will reactivate the adhesive to ensure low air permeability.

15. 7. Repeat
Repeat process on the opposite side of the pipe to close the purge chamber parameters.

16. 8. Introduce Gas
Insert purge gas needle into root gap and introduce noble gas, while ensuring connection to gas line.

17. 9. Weld
Carry out the welding process.

18. 10. Dissolve
Dissolve Aquasol Water Soluble Paper and Tape by introducing water when performing hydro-test.
