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.
Impenetrable Purge Barrier
Flexible and Robust
Ease of Removal
Clean inside of pipe, removing contaminants from surface
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 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.

Liquifilm is completely transparent, allowing the user to easily view the root gap while welding.
Liquifilm is a water soluble PVA film designed to provide exceptional tensile strength and tear resistance. It has excellent resistance to oil, grease, petroleum hydrocarbons and other common solvents used during weld purging applications.
LiquiFilm is a clear, translucent water soluble film with a melting point from 160°C (320°F) to 220°C (428°F). It will thermally decompose at 300°C.
Liquifilm adhesive is free of substances regarded as harmful to stainless steel and other metal pipes.
Liquifilm is in compliance with all specifications mandated by U.S. facilities such as U.S. Nuclear Power Plants, U.S. Food Processing Plants, and U.S. Water Chemical Treatment Plants. It is environmentally friendly and non-toxic. Liquifilm is void of any ingredients that are considered hazardous according to OSHA criteria.
As stated on the United States Department of Labor website, the Occupational Safety and Health Administration (OSHA) was created by the USA Congress in 1970 to provide standards for healthy and safe work environments. OSHA enforces these standards through training, outreach, education and assistance. Liquifilm does not contain any hazardous ingredients according to OSHA criteria.
