Aquasol Ez Purge Pre-Formed Self-Adhesive Water Soluble Purge Dams
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. 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.

How EZ Purge Works
Recommended Proximity to Weld Joint
* or distance recommended by Project Engineer
|PIPE SIZE||RECOMMENDED DISTANCE|
|2″ – 8″||51 – 203 mm||6″||152 mm|
|10″ – 22″||254 – 559 mm||8″||203 mm|
|24″ – 36″||610 – 914 mm||12″||305 mm|
|40″+||1 m+||24″||610 mm|
Before beginning the purging process, clean inner walls of pipe
Peel liner off outer circumference of dam to fully expose adhesive, keeping it away from contaminants and debris
Align adhesive edges to the inside pipe wall and insert dam to desired location. (See Recommended Proximity to Weld Joint Chart)
Thoroughly press adhesive on circumference of dam along inside of pipe wall to create even seal
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.
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.
Adjusting to Create Proper Fit
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 dam’s 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.
