Quick Purge - Pipe Purging Systems In cases where purging is required to be fast as well as reliable, the Quick Purge Systems can be used. These systems will typically purge *6" pipe diameters to below 0.1% oxygen in less than *0 minutes and all smaller pipes, correspondingly faster. Description Each Quick Purge is covered with heat protective materials on the inside, so that the high temperatures at close proximity to the weld do not damage the devices. Three hoses are available, one for argon inflation and purge, the second for auxiliary purge and the third for gas exhaust via a purge monitor. Operation The system is connected to an argon hose and inserted into the pipe to be welded. The spinal connection hose is shorter than with other devices, to keep the purged volume to a minimum. The majority of the volume between the two dams, is filled with a special heat resisting collar, to keep the purge time low. After positioning the system the argon source is opened, the dams inflated to size and the interspace purged. after a few seconds, the auxiliary purge line can be opened to ensure the fastest possible purge time. In trials these devices have performed many high speed welds under these conditions. Sizes from 8inch to *4inch (**0mm - ***0mm) Feedback off the end users of the quick purge have reported savings of up to *3% ! on the purge time! Saves on purge gas, as the volume needed to be purged is greatly reduced. This system pays for itself in a few welds! So why struggle with "make do" systems.
