Operation of inflatable purge system for high temperature pipe welding with heat resistant material

New superalloys need careful purging during welding

Significant developments recently have resulted in the introduction of new nickel alloys that offer major improvements in mechanical properties. Not least is Inconel 740H1, an alloy offering enhanced resistance to coal ash and therefore of considerable interest to fossil fuel fired boiler manufacturers.

Weld purging for tubes and pipes

High quality welds in pipes and tubes can only be assured if the weld underbead is protected from oxidation. The various techniques available through which protection can be given are referred to as purging.

Speeding up purge process

To speed up the purge process prior to welding for large pipes and tanks, Huntingdon Fusion Techniques has designed and developed a range of Quick Purge Systems.
