INFLATABLE TUBE & PIPE WELD PURGING SYSTEMS for 1 to 12 inch (25 to 300 mm) Incorporating “NEW’ 1 Inch (25 mm) System, a first to the market place, another great innovation by Huntingdon Fusion Techniques NEW 5TH GENERATION DESIGNS bringing to the market place for the first time a ‘NEW’ 1 inch (25 mm) System for small diameter tubes and pipes! High quality butt welding of tubes to tubes or fittings and pipes to pipes and fittings for 1” to 12” diameters After 35 years of manufacturing expertise in the field of Tube and Pipe Purging Dams, Huntingdon Fusion Techniques brings to the market yet another great innovation to help tube and pipe welders save money, time, gas and achieve better welds. These even more advanced systems, with many unique features keep us right at the forefront of technical innovation, by bringing you a simple low cost solution to make the cleanest welds. With dramatic savings due to the new design, we have reduced prices significantly whilst at the same time, bringing you a technically superior product. The volume to purge is kept small, resulting in significant savings in both time and cost of inert gas used. The PurgElite® Inflatable Pipe Weld Purging Systems have two heavily protected inflatable dams connected by a new design inert gas purging tube. The inert gas purges air as well as other unwanted gases and vapours out of the space between the dams with inert gas coming through a unique, much lower cost, simpler, trouble free valve than used on other designs. This new, low profile valve allows us to manufacture a 1” Inflatable Pipe Purging System which has never been achieved previously. Don’t use old fashioned purge bladders that burst or makeshift or homemade devices like cardboard or paper dams or foam bungs. They contain a lot of water, water vapour and air, put your weld at risk and end up costing you more money. Use the proper tool for the job!

KEY FEATURES AND BENEFITS PurgElite® Inflatable Pipe Weld Purge Systems simplify the process of inert gas purging and are quick and easy to install. INNOVATIVE PURGE GAS FEED DEVICE No complicated valve to set. INFLATION OF DAMS AND INERT GAS PURGING WITH ONE LINE No chance of inflatable dams bursting. One hose from the inert gas supply is all that is needed. SPECIALLY DEVELOPED DAM CONNECTION HOSE Protection sleeve, resistant to hot metal up to 700ºC. Synthetic spinal connection hose gives complete flexibility to go around bends. Low vapour pressure material. No scratching of polished surfaces....

Purge time for PurgElite® Inflatable Tube and Pipe Weld Purge System to less than 100 ppm oxygen PurgElite® PURGE TIME (to 0.1% oxygen and less) By using PurgElite® Tube and Pipe Purging Systems, the main savings, over any other system, are obtained in reduced purging and waiting time, and in the much lower quantity of inert gas used. Purging with old fashioned systems and home made devices will require a flow rate of at least 24 ltrs/min (50 cu ft/hr) for longer periods. The chart below shows a typical purge time to reduce the air space to less than 0.01% oxygen. Test Pipe Diameter 4” (100 mm)...
