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.

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 paper’s 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.
|2 – 8"||6"||152 mm|
|10 – 22"||8"||203 mm|
|24 – 36"||12"||305 mm|
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.

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
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.
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 70°F 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.
EZ Purge is used in various industries including off-shore oil rigs, refineries, fossil fuel plants, breweries, shipbuilding, processing plants (food, dairy, beverage, pharmaceutical), nuclear power plants, government and military, power plants, petrochemical plants, water treatments plants and much more.
