Water Soluble Purge Film


Liquifilm is a completely biodegradable, water soluble purge film that can be used as a purge gas barrier during TIG welding and is a highly effective alternative when total purging is impractical or too costly. Flexible and robust, Liquifilm can be used on stainless, duplex, and chromium steels as well as titanium alloys.

Available in 1 x 20 meter rolls center-folded or wound on a core, this transparent film can be cut to the desired size for any pipe diameter. Liquifilm can be punctured for gas inlets and outlets with little risk of tearing and has high-force resistance enabling the weld area to maintain a greater level of positive pressure.

Liquifilm can be placed in close proximity to the weld zone, then dissolved with hot or cold water or steam that is introduced through the pipe. Less inert gas will be used, ultimately leading to lower costs for the overall welding operation. An impenetrable purge barrier, Liquifilm is suitable for nuclear, aerospace, and other applications.
