Why Water Soluble Tapes?
![Page 3: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/3.jpg)
• 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
![Page 6: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/6.jpg)
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?
![Page 9: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/9.jpg)
1. Trace & Impress
Trace pipe’s inner diameter by pressing paper along pipe edge, creating an impression. Then fold to form a 90° angle.
![Page 10: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/10.jpg)
2. Cut
Cut in a circle around the impression, approximately one-third times greater than pipe diameter.
![Page 11: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/11.jpg)
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.
![Page 14: Water Soluble Purging Paper & Tape from Aquasol Welding](https://reader034.fdocuments.net/reader034/viewer/2022052418/58a33c041a28ab9b6d8b68a5/html5/thumbnails/14.jpg)
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.
