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
5

• 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

6

• 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?

• CleanClean 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.

8

• Trace and Cut
• Trace pipes 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.

9

• PressPress 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.
