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.
Ron Sewell, Chairman for HFT® said: Using QuickPurge® means there is no longer a need to fill complete pipes with an inert gas. The systems are so efficient they pay for themselves in the first couple of welds in gas savings alone, whatever the pipe size. QuickPurge® is simply inserted into a tube or pipe, inflated within the pipe, restricting the area that is to be welded, reducing the oxygen level down to 100 ppm (parts per million) within minutes.
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.
High speed pipe purging system QuickPurge® is leading the way in the field of purging tube, pipe and pipeline joints over 6 diameter, where oxygen levels are required to be as low as 100 parts per million (ppm) or less.
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.
