Weld Purge your Heat-Treated Pipes with HotPurge®

New power plants are in high demand and several hundred are expected to be built over the next decade. Chromium-molybdenum (chromoly) steel pipe such as P91 is a major construction material for the high pressure piping in these plants and there are particular techniques for welding this pipework to ...

Low Cost Weld Purging with Weld Purge Plugs™

Weld Purging smaller tubes and pipes of different diameters can be challenging, especially when budgets are tight. Often, Welders are left to create their own homemade purging dams out of unsuitable materials such as foam, paper or cardboard. Huntingdon Fusion Techniques HFT® have designed and dev ...

Highly Accurate 100 ppm Weld Purge Monitor for Welding Stainless Steel

Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy on ...

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 ...

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 ...

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 ...

Low Cost Weld Purge Monitor®

Weld Purging is the act of removing oxygen from the vicinity of a weld before, during and after welding. The weld zone is usually confined, with the oxygen level being monitored to ensure it is reduced to a level where welds and their heat affected zones will not be affected by oxygen, leading to lo ...

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.
