Purging system includes device that prevents overinflation
Huntingdon Fusion Techniques (HFT®) has introduced the QuickPurge® II pipe weld purging system.
One of the new features is PurgeGate™, a device that prevents the inflatable dams from bursting caused by overinflation. No matter how much pressure or flow the operator puts into the system, the device delivers the right amount, eliminating the need for setting up and trials.
The purging system is offered in sizes up to 20 in. dia. with three hoses as standard: the inert gas inflation and purge hose, an auxiliary purge/exhaust hose, and a polycarbonate tube that can be connected directly to the Weld Purge Monitor®.
For weld purge readings that can be taken from the end of the purging system, the red tube on the monitor joins to the red tube on the purging system by a single quick-fit connection to prevent leaks.
