Water-Soluble Purge Film
For closing welds, water-soluble Weld Purge Film offers a safer alternative to paper. Film does not contain water, unlike paper that is full of water, unsuitable for welding.

Water-Soluble Purge Film features and benefits:
• With the new water-soluble adhesive, Weld Purge Film® produces a tough, leak tight purge containment.
• One roll can accommodate a range of pipe sizes.
• Can easily be washed away during hydrostatic testing of the pipe or just by normal wash out.
• Dissolves to molecular level leaving no traces.
• Film dams wash away completely (there are no fibers, as there are with paper products, that can clog up filters and make lumps to stick in pipes).
• Ideally suitable for welding where it is not possible to retrieve the purge dam after the joint is complete.
• For use when an Inflatable Tube and Pipe Purging System is not suitable or affordable.
• Easy to view the weld progress through the transparent material.
• Fantastic replacement to people using paper. As we know, paper has a very high percentage of water and nobody wants water vapor coming into the weld once the welding heats everything up.
Dams easily prepared with the safety knife provided.
