Aquasol®

WATER SOLUBLE PAPER AND TAPE

DISSOLVABLE

PURGE GAS BARRIER

FOR TIG WELDING

MADE IN THE USA

Why Water Soluble Tapes?

• 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

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.

Features and Benefits

1. 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

2. 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

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

How Does It Work?

1. Trace & Impress

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

2. Cut

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

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.

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.

5. Activate Water Soluble Tape – Moisten Sponge

Moisten an ordinary sponge with water and squeeze out excess water until sponge is damp.

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.

7. Repeat

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

8. Introduce Gas

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

9. Weld

Carry out the welding process.

10. Dissolve

Dissolve Aquasol Water Soluble Paper and Tape by introducing water when

performing hydro-test.
