About EZ Purge

• Patented and practical, EZ Purge is a pre-formed,
  self-adhesive purge dam that enables operators to
  save time on weld preparation and improve overall
  project timeliness.
• EZ Purge has tapered side walls to fit a variety
  of pipe schedules and its flat design enables
  equal distribution of gases across the body of
  the dam.
• Uniquely engineered, EZ Purge comes equipped with
  EPA approved ZAP (Zero Air Permeability)
  technology that maximizes gas retention and
  reduces gas expenditures.

3

• This water soluble purge dam is comprised of
  Aquasol Water Soluble Paper and is 100
  biodegradable and environmentally friendly. EZ
  Purge rapidly dissolves, leaving behind no
  residue in the pipeline.
• EZ Purge saves valuable labor hours on dam
  construction and is easy to use. The operator
  simply peels, inserts, and presses the purge dam
  into place. No other product available on the
  market today can provide such a reliable,
  efficient, and environmentally sound solution to
  your pipe purging needs.

Before beginning the purging process, clean inner
walls of pipe 1. Peel
Peel liner off outer circumference of dam to
fully expose adhesive, keeping it away from
contaminants and debris 
10
2. Insert
Align adhesive edges to the inside pipe wall and
insert dam to desired location. (See Recommended
Proximity to Weld Joint Chart) 
11
3. Press
Thoroughly press adhesive on circumference of dam
along inside of pipe wall to create even seal
12
4. Activate
Moisten an ordinary sponge with water, squeeze
out excess water until sponge is damp. Lightly
dab sponge along Aquasol Water Soluble Tape
portion of dam. The dampened sponge will
reactivate the adhesive to ensure zero air
permeability. For Sizes above 56 (1422 mm),
inquire for directions.
13
Trouble Shooting1. Repositioning
The dam surface should be perfectly perpendicular
to the pipe wall. If the dam is not straight when
placed in the pipe, it can be easily
repositioned. To adjust without damaging the dam,
carefully remove the tape portion of dam from the
sidewall of the pipe. Move the dam to the desired
location and apply additional Aquasol Water
Soluble Tape for reinforcement, if required.
14
2. Adjusting to Create Proper Fit
15

• The edges of EZ Purge must lay flat against the
  inner pipe wall. If any air pockets or puckered
  wrinkles are visible, the seal must be adjusted
  to yield the optimal results. 
• To maximize the dams seal, cut a slit in the
  adhesive portion of the dam that is allowing air
  to enter the purge chamber.  
• Then, simply overlap the cut ends to create the
  desired seal. Repeat as necessary to improve
  seal. 
• As with a torn dam, simply cover the wrinkled
  area with slightly moistened Aquasol Water
  Soluble Tape.

FAQs

• 1. Dissolve Aqueous Solution
• Aquasol Water Soluble Products, including EZ
  PurgeWater Soluble Purge Dams, must be flushed
  with an aqueous solution or steam in order to
  dissolve. Contact Aquasol Corporation for further
  information.

• 2. Heat Affected Zone
• When welding, the EZ Purge dams must be placed
  far enough from the root gap so that the heat
  affected zone (HAZ) does not char or degrade the
  papers water soluble properties.Recommend
  distances for placing EZ Purge from the root gap
  are listed below. These distances depend on the
  pipe diameter size (ID) or the recommended
  distance provided by the project engineer to move
  out of the HAZ.

20

• 3. Flash Point
• EZ Purge is made from Aquasol Water Soluble
  Paper, which has a flash point of 450F (232C).

• 4. Creating a Tight Seal
• To create a tight seal, first ensure the surface
  of the inner pipe has been cleaned and that no
  oils remain. This will increase the integrity of
  the seal. Once the dam is correctly positioned,
  the dam can be secured in place by introducing
  moisture to reactivate the adhesive and form a
  tight seal. Please note, it is recommended to use
  a lightly moistened sponge, and not a dripping
  sponge. Too much moisture will cause the paper
  and tape adhesive to start to dissolve.For more
  information, please refer to our video

• 5. Dry Tape
• If the water soluble tape becomes dry, lightly
  moisten it with a dampened cloth or foam brush.
  The adhesive will be reactivated instantaneously.
  Be careful not to saturate the cloth as the tape
  will dissolve.

• 6. Reposition the Seal
• The EZ Purge adhesive is engineered in such a way
  that it will not inhibit the user from placing
  the dam in proper position. The strength of the
  tack or stickiness of the adhesive allows the
  user to have control and reposition the dam if
  not properly placed on the first attempt.
• To reposition EZ Purge, carefully remove the tape
  portion of dam from the sidewall of the pipe.
  Then move it to the desired location and apply
  additional Aquasol Water Soluble Tape for
  reinforcement, if required.

22

• 7. Adjust For Proper Fit
• If the size of EZ Purge does not exactly match
  the size of the pipe, it is easy to alter the dam
  to create the perfect desired fit. Simply cut the
  tape portion of dam as it is being inserted. Then
  overlap the cut ends to create the desired size.
  Repeat if necessary. If the pipe ID is slightly
  too big for the specific EZ Purge size,
  additional Aquasol Water Soluble Tape can be
  added to reinforce the seal along the pipe wall.

• 8. Adhesive Dry Time
• It takes approximately 5 minutes for the EZ Purge
  adhesive liner to dry after being dampened for
  application.

23

• 9. Torn EZ Purge Dam
• If the water soluble EZ Purge dam tears
  accidentally during installation, simply cover
  torn spot with Aquasol Water Soluble Tape.

• 10. Storage and Shelf Life
• EZ Purge has a shelf life of approximately one
  year. To increase shelf life, store EZ Purge in a
  dark, cool and humidity controlled environment.
  Ideal storage temperature is 70F with
  approximately 50 humidity. EZ Purge should
  always be stored in the water proof package that
  is included with purchase. Contact with water
  must be avoided at all times. For easy reference,
  the manufacturing date is labeled on the bottom
  of each EZ Purge box.
