Inflatable tube and pipe purging systems Welders are always looking for time and cost savings when pipes need to be purged of oxygen before, during and after welding. Weld purging large diameter pipework fabrications and pipelines not only carries a large price tag when it comes to time, but it can also cost a lot in inert gas. QuickPurge systems are designed to be inflated inside the pipe, restricting the volume that needs to be purged so much so that the systems can pay for themselves in just one or two welds.

parts per million (ppm), allowing zero- colour welds to be achieved with no loss of corrosion resistance caused by oxidation. IntaCal ® combined with the integrated PurgeGate ® device makes it possible to safely inflate the systems with argon gas, for sealing and then purging the space between the dams where the weld joint is located. With PurgeGate, any risk of over-inflation due to pressure or flow increase is eliminated. All systems are manufactured as standard with a hose for connecting a Weld Purge Monitor ® , which can read oxygen levels down to as low as ten ppm. Specially designed QuickPurge systems with longer sleeves are also available for pipework with 90° bends. Huntingdon Fusion Techniques – UK support@huntingdonfusion.com www.huntingdonfusion.com

A customer in the USA commented, “What an enormous saving in waiting time for our welders. Normally we wait several hours for our 30" stainless steel pipe joints to be purged and now we can start welding in under ten minutes.”

Weld purging specialist and developer Huntingdon Fusion Techniques (HFT) manufactures QuickPurge ® tube, pipe and pipeline weld purging systems.

QuickPurge are available in sizes from 152 to 2,235mm (6" to 88") and are used in industries such as refineries for nickel alloys, mining operations for titanium, nuclear power stations for stainless steel, and the oil and gas industry for all high quality pipe joints. QuickPurge can help welders achieve consistent oxygen levels as low as ten systems
