Weld Purge Film
Water Soluble Purge Film to make Purge dams of any shape and size.
The film dissolves away completely without leaving any fibres to clog up filters or other sensitive parts in a system.
Description
Water Soluble Purge Dams make an impenetrable purge barrier, which can easily be washed away when hydro statically testing the pipe or just by normal wash out.
Weld Purge Film is an an easy and cost effective solution to make dams of any size and shape and can be particularly useful in place of mechanical purge devices that cannot be retrieved due to access limitations. No more dams coming loose and lost purge gas during welding. The use of Argweld Water Soluble Weld Purge Film and Argweld Water Soluble Super Adhesive for manufacture of purging dams is well proven and gives not only superior results over all other water soluble products. Argweld® Water Soluble Weld Purge Film™ is strong in all directions so that it can maintain a good gas barrier throughout the purging process. You will be able to see the weld root clearly by using Argweld® Water Soluble Weld Purge Film™.
Competing products such as the Aquasol EZ Purge Dams or Dissolvo paper dams could leave paper fibres whereas the Argweld Weld Purge Film dissolves completely in water.
Argweld® Water Soluble Weld Purge Film™ can be used on stainless, duplex and chromium-molybdenum steels & titanium alloys. The dams can be easily cut with the safety knife provided and produces an impenetrable purge barrier which can easily be washed away during hydrostatic testing of the pipe or just by normal wash-out. Te product is approved for use in Nuclear and Aerospace Environments. Trace element certification is available to show that Argweld® Water SolubleWeld Purge 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 Weld Purge Film™ has superior strength in all directions and is difficult to be torn or damaged. This ensures that your purge dams maintain a good, impenetrable gas barrier throughout the purging process.
Each roll of Argweld® Water Soluble Weld Purge Film™ is 20 square metres (215 square feet). The width of the material is folded in half and wound on a cardboard spool. When cut, it will provide two dams for diameters under 500 mm, at the same time, thus saving cutting time.
Argweld® Water Soluble Weld Purge Film™ can be used up to 300ºC without the material burning and losing the weld purge.
