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

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
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
• 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

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

How Does It Work?
9

• Trace Impress
• Trace pipes 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 oclock position followed by 3
oclock, 6 oclock 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.
