Argweld® Inflatable Single-Ended Weld Purge Dams

Single Ended for Closing Welds!
Argweld® Inflatable Weld Pipe Purging Dams offer a cost-effective alternative to traditional plastic foam or cardboard dams, often hand-made by welders on-site at significant expense. Manufactured from advanced materials with low outgassing rates, these dams are ideal for applications where Argweld® Tandem Pipe Purging Systems or older Purge Bladder Systems are less suitable.

Applications for Single Ended for Closing Welds!

Closing Welds

Difficult Joint Configurations

Quality Control
Perfect for single-ended applications where retrieval is possible.
Suitable for use in tight bends, T-pieces, and dome ends where other systems may not fit.
Provides a solution to avoid issues like weld coking, oxidation, and contamination, ensuring high-quality welds.


Key Features and Benefits
