Huntingdon Fusion Techniques (HFT®) has introduced the QuickPurge®III upgraded pipe purging system for high-speed pipe joint welding.
The combination of Intacal® II and the integrated PurgeGate® device makes it possible to inflate the dams safely with argon gas before releasing it for purging the space between the dams where the weld joint is located.
It is almost impossible now for the inflatable dams to burst as a result of overinflation or flow increase of the purging gas. The sleeve between the dams reduces the volume to be purged by two-thirds, helping to ensure a quick purge time down to 10 PPM oxygen.
Sleeve lengths for each size have been calculated so that the pipe purging system can be pulled around 90-degree elbows for the purging of connecting joints.
