Dissolvo Water Soluble Paper is the proven, efficient and ecologically friendly purging solution.
Used to retain inert gas during TIG welding of stainless steel and aluminum pipes, Dissolvo can be constructed into purge dams fitting all diameters and placed within close proximity to the weld zone.
Dissolvo provides an excellent barrier to create the ideal purge environment by trapping inert gas within the weld zone, while preventing oxygen from entering and causing contamination. Thus, Dissolvo is cost effective, reducing the amount of expensive inert gas needed to create a superior purge.
Comprised of 100% biodegradable sodium carboxyl methyl, cellulose and wooden pulp, Dissolvo quickly disperses when introduced to water and most aqueous solutions, leaving no residue behind in the pipeline.
Dissolvo is available in a wide range of grades and sizes and is non-toxic, making it ideal for the nuclear, petrochemical, and food and beverage industries.
Trace pipe’s inner diameter by pressing paper along pipe edge, creating an impression. Then fold to form a 90° angle.
Cut in a circle around the impression, approximately one-third times greater than pipe diameter.
Slit approximately 1″ to 2″ segments perpendicular to impression on paper making first slit at 12 o’clock position followed by 3 o’clock, 6 o’clock and so on.
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.
Moisten an ordinary sponge with water and squeeze out excess water until sponge is damp.
Lightly dab sponge along the water soluble tape portion of the dam. The dampened sponge will reactivate the adhesive to ensure low air permeability.
Repeat process on the opposite side of the pipe to define purge chamber
Insert purge gas needle into root gap and introduce noble gas, while ensuring connection to gas line.
Carry out the welding process.
Introduce Water to Dissolvo Water Soluble Paper and Tape and watch them disperse, clearing the pipeline.

Dissolvo Water Soluble Paper and Tape dissolves in most aqueous solutions or steam.
Dissolvo® Water Soluble Paper and Tape will not dissolve in oil or fuel, however both can be flushed water, steam or an aqueous solution.
Dissolvo® Water Soluble Paper and Tape cannot dissolve in solvents such as MEK or acetone. The products must be flushed water, steam or an aqueous solution.
Dissolvo® Water Soluble Paper and Tape will dissolve in either hot or cold water. However, the rate of dissolvability increases as the temperature of the water increases.
Dissolvo® Water Soluble Paper and Tape have a flash point equivalent to ordinary paper, which is 450°F (232°C).
Dissolvo® Water Soluble Paper and Tape are 100% biodegradable and eco-friendly. Both are non-toxic products that do not cause reactions or adverse effects when used.
Dissolvo® Water Soluble Tape is designed to allow the user to place the dam in the proper position before maximizing the adhesion of the seal. The strength of the “tack” or “stickiness” of the adhesive allows the user to have control and re-°©‐position the dam if not properly placed on the first attempt. Once the dam is in place, the user can increase adhesion by reactivating the adhesive on the tape portion of the dam with a damp sponge. A tight seal will be formed as it dries.
