The Argweld® Weld Purge Film® and Argweld® Super Weld Purge Adhesive™ 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 wash out.
Key features and benefits:
- The Film makes dams which produce an impenetrable purge barrier.
- Can easily be washed away during hydrostatic testing of the pipe or just by normal wash out.
- Dams easily prepared with the safety knife provided.
- Dissolves to molecular level leaving no traces.
- There are no fibres, as there are with paper products, that can clog up filters or other sensitive parts in the system
- Ideally suitable for welding where it is not possible to retrieve the purge dam after the joint is complete
- For use when buying an Inflatable Tube and Pipe Purging System would not be cost effective.
- Easy to view the weld progress through the transparent material.
