The use of water soluble Purge 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 film material makes dams which produce an impenetrable purge barrier but which can easily be washed away when hydro-statically testing the pipe or just by normal wash out.

the Purge Film 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.
