AQUASOL Water Soluble Purge Dam Paper
Made of sodium carboxy methyl, a cellulose and wooden pulp that dissolves rapidly and completely in most liquids including water. Can be used to dam argon or helium gases during tungsten inert gas (TIG) welding of steel or aluminum pipes. After welding is complete, purge dams can be effortlessly dissolved and flushed out of the system with water; leaving no residue in the pipeline. the product is available in a variety of formats including sheets, rolls, pre-formed dams and pressure-sensitive tapes. Environmentally friendly and nontoxic.
Aquasol Paper can be formed into any size purge dam when used in conjunction with water soluble tape. Position minimum of 6" - 8" from root gap. Use heavyweight paper (AWS 60 for pipes having and inside diameter of 4" or greater.
