Standard and Custom Made, Low Cost Weld Purge Dams
When welding stainless steel, titanium or zirconium pipes, or pipework, the oxygen level within the pipe must be reduced to a level of 50 ppm, or lower in certain cases. The most cost-effective solution is to restrict the volume around the joint with a Tandem Weld Purging System. For the purging o ...Low Cost 1 PPM Weld Purge Monitor®
For many years, oxygen monitors and gas analysers have been used for weld purging. These instruments have been designed and calibrated for accuracy at atmospheric oxygen level, but not for weld purging where accuracy is required when reading much lower oxygen levels. With their scientific backgroun ...Highest Quality Welds made with Lower Costs
Welding stainless steel, titanium, zirconium, niobium and other metals sensitive to atmospheric gases, requires oxygen levels to be as low as 10 ppm and in some cases, knowledge of dew point level in the shielding and purging gas. Many welds of this nature are still welded with archaic or home-made ...Handy Purge Monitor, now with PurgeNet™
To remain at the forefront of Weld Purging technology, World leading Weld Purging Experts and inventors of the Weld Purge Monitor®, Huntingdon Fusion Techniques HFT® have launched the updated hand-held PurgEye® 200 Weld Purge Monitor®, now with PurgeNet™. When welding metals such as stainless stee ...Keeping Tube and Pipe Joints Clean when Welding
It is important when welding stainless steel and titanium tube and pipe joints to be able to have zero colour, oxide-free welds both on the inside and outside. To achieve the conditions for zero colour, or oxide-free weld joints, it is necessary to remove the air around the joint to a level where ...Low Cost one-way Valve for specific flow rate and pressure
This low cost accessory has been designed and constructed to pass a maximum of 7.5 litres/min and 0.5 bar pressure. Other versions of 1bar and above are also available. Designated “PurgeGate®”, this nifty, hi-tech item has applications in both fluid and gas control. Its small size and low weight m ...Remote Monitoring of Weld Purge up to 1 km away
When welding lengths of tube and pipework fabrications, as well as sections of pipelines of 20 metres length and more, one problem operators face is not receiving a fast and true weld purge reading from the purge zone. Now, for the first time, Huntingdon Fusion Techniques HFT® makes it possible to ...Introducing PurgeNet™ and Accessories
Monitoring the oxygen level before, during and after welding is essential. Welding in an environment of less then 100 ppm for stainless steel and less than 20 ppm for titanium ensures that welds are free from oxidation. Allowing joints to oxidise when welding then involves mechanical or chemical ox ...Weld Purging for Closing Welds
Weld Purging a variety of pipes of different diameters can prove complex and costly, particularly when having to fill whole pipework systems with expensive argon gas. One solution that welders have traditionally devised has been to construct homemade foam or paper dams that are placed either side of ...Effective Pipe Plugging in Heavy-Duty Applications, with Aluminium Plugs
Effective plugging and sealing of pipes in heavy-duty applications is essential, especially in refineries, offshore operations, plumbing operations as well as domestic and industrial water activities where the plug is likely to be immersed in chemicals or exposed to high temperatures. The Pipestopp ...Accessories for Inflatable Weld Purging Systems
It is important when welding metals such as stainless steel, titanium and zirconium that the welding zone is purged of oxygen even as low as 10 parts per million (ppm) before, during and immediately after welding, in order to achieve a clean, oxide free, zero colour weld. Weld Purging Experts Hunti ...Leak Testing, Debris Stopping and Weld Purging with Pipestoppers®
Pipe plugs and stoppers are in use globally for a large variety of applications, including leak testing, weld purging, debris stopping and pipe freezing for repair or maintenance work for thousands of different industries. Manufacturing a wide range of plugs and stoppers of up to two meters in dia ...
