ARGWELD® WATER SOLUBLE PURGE FILM
The use of water soluble film for manufacture of purging dams is well proven and
the Argweld® film gives superior results over all other water soluble products.
Argweld® Water Soluble Purge Dam Film can be used for
stainless, duplex and chrome-moly steels as well as titanium.
The Argweld® purge material makes dams which produce an
impenetrable purge barrier but which can easily be washed
away when hydrostatically testing the pipe or just by normal
It dissolves away completely without leaving any fibers to clog
up filters or other sensitive parts in a system and it can resist
pressure in all directions so that it can maintain a good gas
barrier throughout the purging process.
Trace element certification can be provided to show that
Argweld® film does not contain any harmful elements and that
the quantity of halides is well below the permissible levels.
The film and adhesive are completely biodegradable and all
packaging materials are recyclable.
Argweld® Water Soluble Purge Dam Film comes in a kit comprising:
- A 20 meter length of 1 meter wide film folded in half and wound on a spool
- Two bottles of the adhesive
- A slitting knife to quickly cut the dams
- A comprehensive manual with instructions for use with hints and tips for weld purging
