Purging Systems achieve clean, oxide-free, zero color weld.

Press Release Summary:

Purging Systems  achieve clean, oxide-free, zero color weld.

Aug 04, 2016 - Designed for pipe diameters from 1–24 in., PurgElite® Tube and Pipe Purging Systems are manufactured with special spinal tube that is resistant to hot metal up to 572°F and is flexible to allow movement around bends. Spinal tubes are made of low outgassing rate materials, so there is no risk of weld contamination. Each PurgElite® also features IntaCal® purge gas feed device and RootGlo® centerpiece glow positioning indicator to ensure system can be positioned accurately inside tube or pipe.

Weld Purge Your Pipes the "Elite" Way

Press release date: Aug 02, 2016

When welding stainless, duplex, chrome steel and titanium tubes and pipes, it is important to purge the welding zone with an inert gas to prevent corrosion, oxidation, discolouration and to ensure a good internal weld profile with no metallurgical defects.

After 40 years of innovation, design and manufacturing expertise in the field of tube and pipe weld purging, Huntingdon Fusion Techniques HFT® has introduced PurgElite®, a range of low cost Tube and Pipe Purging Systems to achieve a clean, oxide free, zero colour weld.

Georgia Gascoyne, CEO for HFT® said: “We recently had a customer who was wasting a lot of money in time and argon gas costs by filling entire pipework fabrications with argon in order to weld the stainless steel pipes in an inert environment. There were several 90º bends in the pipework, so the customer thought filling the whole pipework system was the only option.

To save welders the expense of completely filling tubes and pipes with an inert gas, PurgElite® Systems are available, manufactured to suit pipe diameters from 1” to 24” (25 to 600 mm). PurgElite® is manufactured with a special spinal tube that is resistant to hot metal up to 300ºC (572ºF) and is super flexible to allow movement around bends. These spinal tubes are made of low outgassing rate materials, so there is no risk of weld contamination.”

Each PurgElite® features IntaCal®, a purge gas feed device, which means there is no complicated valve to set. A centrepiece glow positioning indicator RootGlo® comes as standard to ensure the system can be positioned accurately inside the tube or pipe. In addition there is no metal braiding on the PurgElite®, which could be welded to the root of a joint.

HFT®’s innovative PurgeGate® Valve is available as an accessory, a unique one way valve suitable for all types of Inflatable Pipe Weld Purging Systems. PurgeGate® regulates the gas flow and pressure during weld purging to prevent the dams from over inflating. 

Quick connect/disconnect fittings with collets and ‘O’ ring seals for gas tight sealing, fitted with anti-release circlip are fitted to all Systems to prevent parts accidentally separating inside pipes.

Heat Resistant Covers are available as accessories to protect the inflatable dams, which are held on with ties and have a temperature rating of up to 300ºC.

There are many fabricators still using homemade 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 ways.

By using PurgElite® Tube and Pipe Purging Systems companies can save significant money in both time and inert gas costs. Contact HFT® for a live demonstration and a return on investment chart to show you how quickly it pays to use up to date technology from the very first weld.

Weld purging is the act of removing, from the vicinity of the joint, oxygen, water vapour and any other gases or vapours that might be harmful to a welding joint. Such gases may combine with the metal to form undesirable compounds that may reduce corrosion resistance or may be instrumental in creating cracks or other structural defects in metals.
