ASW35/R-9 - Aquasol ASW-35/R-9 Water Soluble Purge Paper Roll, 9-Inch Width

Aquasol ASW-35/R-9 Water Soluble Paper for Pipe Purging

The Aquasol ASW-35/R-9 Water Soluble Paper is an industry-standard solution for creating effective purge dams during the TIG welding of stainless steel and aluminum pipes. Measuring 9 inches in width and 165 feet in length, this roll offers exceptional versatility, allowing welders to construct custom-sized purge chambers for pipes of varying diameters. The paper is manufactured from a unique blend of Sodium Carboxy Methyl Cellulose and wooden pulp, ensuring it is both robust enough to withstand the pressure of purge gases and soluble enough to dissolve instantaneously when introduced to water.

In the welding of reactive metals, maintaining an oxygen-free environment inside the pipe is critical to preventing oxidation and "sugaring" of the root weld. Traditional methods involving inflatable bladders or cardboard dams can be costly or difficult to remove. Aquasol Water Soluble Paper solves this problem by providing an impermeable barrier to oxygen while retaining noble gases like Argon and Helium within the weld zone. Once the welding process is complete and the pipe has cooled, the paper dam can be effortlessly removed by flushing the line with water or steam. The paper breaks down into microscopic fibers that leave no residue behind, ensuring the purity of the pipeline system.

This product is particularly beneficial for industries requiring high purity standards, such as nuclear, petrochemical, and food and beverage processing. The ASW-35 grade is the standard thickness (0.0035 inches), providing the perfect balance between air impermeability and ease of handling. It can be easily cut with scissors or a knife and taped into position using Aquasol Water Soluble Tape. By using the ASW-35/R-9 roll, operators can significantly reduce gas consumption by localizing the purge area, saving both time and money on every project.

Key Benefits:

• Total Solubility: Disperses rapidly in water and steam, leaving no contaminants in the pipeline.
• Gas Retention: Excellent barrier properties for Argon and Helium, ensuring a high-quality root pass.
• Versatility: The 9-inch width is ideal for fabricating dams for medium to large bore pipes.
• Eco-Friendly: Biodegradable and non-toxic composition safe for the environment and the welder.
