Care is necessary when welding large diameter pipework in stainless, duplex, chrome steels, nickel alloys and zirconium. When welding such reactive materials, they need to be purged of oxygen before, during, and after welding, which can cause a huge expense when they are of a large diameter.
Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative QuickPurge® Systems, which are manufactured up to 88″ (2,235mm), dramatically reduces the space that needs to be purged, thereby reducing purging time dramatically, making huge savings in both time and gas costs.
QuickPurge® has an additional gas input line, which means extra purge gas can be introduced for applications such as this, thereby achieving a much faster purge, down to the lowest oxygen levels, which is perfect for larger diameter pipes where quality welds are required.
Huntingdon Fusion Techniques HFT®’s innovative design of the QuickPurge® System means that zero color welds will be achieved and there will be no loss of corrosion resistance or loss of mechanical strength caused due to the presence of oxygen, nitrogen or hydrogen gas.
