Time is money and waiting for pipes to be purged ready for welding can take many hours, depending on the diameter of the pipe being welded and the method chosen for purging.
We were recently tasked with an application where pipes with 90o elbows, up to 54” diameter were required to be purged. We manufactured QuickPurge® Systems with longer sleeves so that they could easily be pulled around the sharp bends in the pipework.
The welders were previously spending half a day purging the pipe, which was costing a considerable amount in time and gas costs. With the help of the QuickPurge ® the pipe was purged in just 55 minutes.
The dramatic savings in time and gas paid for the system in just one weld!
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.
Using IntaCal® combined with the integrated PurgeGate® device makes it possible to safely inflate the dams with argon gas, for purging the space between the dams where the weld joint is located. With PurgeGate®, burst dams are prevented in the event of undue pressure increase or accidental flow increase of the purging gas.
All systems are manufactured as standard with a hose for connecting a Weld Purge Monitor® to, which can read oxygen levels down to as low as 10 ppm depending on the model.
Materials used in the manufacture of QuickPurge® are such that they are resistant to the higher weld temperatures present and they don't outgas, preventing weld contamination.

For pre-heated chrome steel and high strength stainless steel pipe joints, HotPurge® is manufactured for a higher and longer temperature exposure.
