Many Inflatable Tube and Pipe Weld Purging Systems are at risk of over-inflating during the weld purging process. As the heat caused by welding rises, the inflatable dams can expand beyond their safe limits and in addition, other personnel working near the welding area can vary the gas flow or pressure at random, causing over-inflation and bursting.
Once a burst occurs, the purge is lost and the weld will immediately oxidise in the presence of incoming air. The welder will then have to cease welding, grind out the oxidation and start the whole process again. On pipes below 36” diameter, the inside may not be accessible and the total joint may need to be cut out, leading to lengthy delays and high add-on costs.
To prevent such bursts, Huntingdon Fusion Techniques HFT® has designed and now manufactures a PurgeGate® Valve System in order to prevent any over-pressurising of Inflatable Tube and Pipe Weld Purging Systems.
Georgia Gascoyne CEO of Huntingdon Fusion Techniques HFT® said: “These innovative devices, which are fitted as standard on our HotPurge® and QuickPurge® Systems (PurgeGate II), are offered as accessories for the PurgElite®, PurgExtra® and any other manufacturers versions of Inflatable Tube and Pipe Purging Systems.”
PurgeGate® Valves have an easy push fit connection and are simply, plug and play. They fit all system sizes, from 1” to 96” and can be moved from system to system.
