EZ-ZT2.5 - Aquasol EZ Zone Aluminum Purge Tape 2.5 Inch

Precision Purging for High-Purity Welds

In the realm of high-specification pipe welding, particularly with materials like stainless steel, titanium, and Inconel, maintaining a contaminant-free weld zone is paramount. The Aquasol EZ Zone Tape (2.5" x 75') is an engineered solution designed to address the specific challenges of root gap sealing during the gas purging process. Unlike standard aluminum tapes that coat the entire surface with adhesive, EZ Zone Tape utilizes a strategic design to eliminate the risk of chemical inclusion in the weld pool.

The tape is constructed from a malleable, heat-resistant aluminum foil characterized by two outer strips of adhesive separated by an adhesive-free center zone. When applied over the root gap, this center zone bridges the bevel without allowing any adhesive to contact the pipe edge or the open root. This prevents the vaporization of adhesive chemicals during the welding process, which can otherwise lead to porosity, embrittlement, or carbon pickup in the weld metal. This feature makes EZ Zone Tape an essential consumable for nuclear, aerospace, and food-grade welding applications where purity is non-negotiable.

Beyond quality assurance, EZ Zone Tape enhances operational efficiency. The aluminum foil acts as an effective barrier, retaining noble gases like Argon or Helium within the pipe interior to prevent oxidation (sugaring). By creating a tight, reliable seal, it reduces the volume of gas required to achieve a purge and minimizes setup time compared to makeshift solutions. The tape is halogen-free and fluorocarbon-free, ensuring compliance with stringent industry standards.
