AquasolWATER SOLUBLE PAPER AND TAPE

DISSOLVABLE

PURGE GAS BARRIER

FOR TIG WELDING

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

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

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 oclock position followed by 3 oclock, 6 oclock 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.
