Liquifilm®

WATER SOLUBLE PURGEFILM AND ADHESIVE

THE TRANSPARENT& FLEXIBLE PURGEGAS BARRIER FORTIG WELDING

About • 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.

Features and Benefits

Impenetrable Purge Barrier

• Excellent barrier for retaining noble gas (argon or argon/helium mix)

Flexible and Robust

• For use on stainless, duplex and chromium steels and titanium alloys

• Can be punctured for gas inlets and outlets with little risk of tearing

• High resistance to pressure, allowing for greater positive pressure to be maintained in weld

area.

Transparent

• Transparency allows for ease of viewing during welding process

Ease of Removal

• Rapidly dissolves in hot or cold water

• Leaves no residue in the pipeline

Safe

• Suitable for nuclear, aerospace, and other applications

How it works? • Clean

Clean inside of pipe, removing contaminants from surface

• Apply

Apply Liquifilm Water Soluble Adhesive to inside of pipe.

Thoroughly coat the entire circumference of the pipe surface

where film is to be placed.

• Trace and Cut

Trace pipe’s inner diameter by pressing Liquifilm along pipe edge, creating an impression.

Then fold to form a 90° angle. Cut Liquifilm in a circle around the impression, approximately

one-third times greater than pipe diameter.

• Press

Press glossy surface of Liquifilm against tacky adhesive inside the pipe to create an air tight

seal. If required, puncture a small hole in the center of the purge dam to allow oxygen to

escape or dissipate through the root gap.
