USING PROVISIONAL DAM SYSTEMS Provisional Dam Systems May leak and allow harmful gases back into the welding environment. ARGWELD® RANGE 2

Uses less inert gas Faster Quick and easy to install, dams inflate instantly, purging time is fraction of time required for conventional methods Improved weld quality Leading to bright, shiny, coke and oxide-free welds Fast payback Argweld® Inflatable pipe purging systems pay for themselves in just one or two welds Highest standards Manufactured to nuclear quality with nuclear approved materials Quick Purge™ Inflatable Pipe Purging Systems ARGWELD® RANGE 3 Patented collar system provides full quality purge with only a tiny percentage of the gas required by any other purging method.

All manufactured from materials which do not contain contamination and do not outgas any harmful materials into the weld zone Quick Purge™ System Quick Purge™ Systems ARGWELD® RANGE 4

Quick Purge™ Systems ARGWELD® RANGE 5 Luminous centre guide strip for easy view inside dark pipes

affddd Quick Purge™ Systems ARGWELD® RANGE 5 We also manufacture large ones: 78” diameter model
