About 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.
