With double inflatable dams, unit offers heat resistant covers to resist temperature up to 300Â°C. Featuring special spinal tube, device allows movement around 90Â° bends. Suitable for pipe diameters ranging from 25 to 600 mm, system regulates gas flow and pressure using PurgeGateÂ® valve.
Original Press Release:
Welding of Vacuum Tubing and Piping
Welds in tubing and pipework for vacuum systems should have many important characteristics. They ideally need to be manufactured from stainless steel, leak tight, the joints should have full penetration with excellent sidewall fusion, there should be no porosity and the finish should be free from oxidation and discolouration.
When welding these stainless steel tubes and pipes, it is important to purge the welding zone with an inert gas, usually argon, to prevent loss of corrosion resistance, oxidation, discolouration, metallurgical defects and to ensure a good internal weld profile.
After 40 years of innovation, design and manufacturing expertise in the field of tube and pipe weld purging, Huntingdon Fusion Techniques HFTÂ® has introduced PurgEliteÂ®, a range of low cost Tube and Pipe Purging Systems to achieve a clean, oxide free, zero colour weld in such tubes and pipes. As well as vacuum tube and piping, PurgEliteÂ® can be used in any other industry where stainless steel or titanium is used.
Georgia Gascoyne, CEO for HFTÂ® said: â€śWe recently had a customer who was wasting a lot of money in time and inert gas costs by filling entire pipework systems with argon in order to weld the stainless steel pipes in an inert environment. There were several 90Â° bends in the pipework, so the customer thought filling the whole pipework system with expensive argon gas, was the only option.â€ť
â€śTo save welders the expense of completely filling tubes and pipes with an inert gas, PurgEliteÂ® Systems with their double inflatable dams are available, manufactured to suit pipe diameters from 1â€ť to 24â€ť (25 to 600 mm).â€ť
PurgEliteÂ® is manufactured with a special spinal tube, joining the two dams, that is resistant to hot metal up to 300Â°C (572Â°F) and is super flexible to allow movement around 90Â° bends. These pipe weld purge systems are made of low outgassing rate materials, which gives them the ability to produce the right environment for high quality welds.
IntaCalÂ®, a purge gas feed device means there is no complicated valve to set. To ensure the PurgEliteÂ® System can be positioned accurately inside the tube or pipe, a centrepiece glow positioning indicator RootGloÂ® comes as standard on all sizes.
HFTÂ®â€™s innovative PurgeGateÂ® valve is available as an accessory, a unique one way valve suitable for all types of Inflatable Pipe Weld Purging Systems. PurgeGateÂ® regulates the gas flow and pressure during welding to ensure the inflatable dams don't burst resulting in a failed weld.
Heat Resistant Covers are available as accessories to protect the inflatable dams in the event that the weld process is unusually hot. These covers suit any inflatable purging or blocking system and are held onto each dam by a number of ties. Such covers allow use up to a temperature of 300C.
There are many fabricators still using poor quality home made devices fashioned from foam, wood, metal and rubber. They are wasting vast amounts of money on expensive argon gas and labour by allowing their welders to continue in their old, often ineffective ways.
By using PurgEliteÂ® Tube and Pipe Purging Systems, companies can save significant money in both time and inert gas costs. Contact HFTÂ® for a live demonstration and return on investment charts.
