The ARGWELD® 'Purge Bladder System' has a number of distinct advantages leading to big cost savings. Here you see the Quick Purge being inserted into a 6" pipe. Shown is the valve
assembly that vents
the purge gas into the
purge area
Shown is an exhaust outlet this vents the purge gas from the purge area.
Application:


The Mini Quick Purge above was designed to increase productivity, decrease purge gas consumption & most importantly save time. Its use was produced for a German pipe work fabricator who was looking to apply the cost saving properties of the standard Quick Purge offers (on larger pipe ID’s) to 6” stainless pipe work, mainly the fabrication of stainless steel flues & exhausts.
 
Argweld® Quick Purge Pipe Purging System has been designed to reduce the volume being purged to a minimum with considerable savings of gas and time.PURGING A 30" DIA LOBSTER BACK Short pipe segments tacked together to form a bend or elbow.A correctly purged root area can be achieved with the Argweld® system.The distance between the dams is shorter than with other systems to keep the purge volume low.HOSES
All ports are in the front end. The exhaust hose and gas inlet are installed into the primary end, to allow inflation and oxygen measurement to be carried out at the same end.
PURGE TIME.
On a 500 mm diameter duct, the purge time to 0.1% Oxygen, using an Argweld® Purge Monitor, was 2 minutes.
Joints taped and sealed on the outside with un-purged tacks showing o n the inside.Short lengths of Mitered Pipe tacked together with minimum space between the purge dams."On a 762 mm diameter Lobster back , using 2 mm thick 316 stainless steel welded at 90 - 110 amps, we achieved a purge time of 12 minutes per joint" , said Jim Ross, Managing Director of County Fabrications in Leicester . He went on to say , " The welds we re much cleaner using the Quick Purge System saving us cleaning time as well as gas costs and waiting time" "This system saved us from back gouging and welding a second pass from the inside" Because the dams are closer to the weld than with other purge systems and the central collar is also closer to the weld, the inside faces of the Quick Purge System are covered with a heat resisting material to stand up to the high temperatures experienced with TIG and MIG welding. Information Request Form :
High quality circumferential butt welding of pipe to pipe and pipe to fitting requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead. The best system devised for this is the ARGWELD® "Purge Bladder System". It is quick, reliable and easy to use. The volume of purging required is kept small, resulting in significant savings in both time and the volume of inert gas used.The ARGWELD® "Purge Bladders" are based on a simple idea. Two protected bladders are connected by a spinal tube.  The tube carries the gas to inflate the purge bladders and the release valve to purge the space between them. The system is inserted into the bore with one bladder either side of the weld joint. The purge bladders are inflated to form a seal, after which the pressure in the system opens the purge valve, the inert gas is then fed into the space between the bladders expelling the air. Welding can then be carried out, the inert gas ensuring a clean even penetration bead.  The ARGWELD® 'Purge Monitor' has several features:Keeps waiting time to a minimum
The monitor can tell the operator exactly when the oxygen level is low enough to commence welding. No estimating or guesswork is involved, so no time is wasted waiting for the correct level to be reached. Saves on excessive use of inert gas
The exact oxygen content is given, so no more inert gas than necessary has to be used to ensure that the weld will be free of oxidation. Prevents weld failures
Premature starts on welds are avoided, high quality is ensured. Highly portable
Its small size makes is easy and very convenient to use in all purging situations. Low cost
The monitor is available at low relative cost and is a perfect accessory for use with any pipe purging system or argon welding enclosure. Continuous monitoring of oxygen levels
A continuous read out of the oxygen level is given, even when welding is taking place. This can avoid unforeseen purge problems that could cause quality failures after the weld has been started. Safety
The purge monitor may also be used to check confined spaces for safe oxygen levels before personnel enter the area and while they are working. Other Purge Monitors available from COB Industries, Inc. include:The ARGWELD® 'PPM - Parts Per Million Monitor'. The ARGWELD® 'Purge Alarm', a monitor measuring from 20.9% oxygen down to 0.01% (100ppm), a little more expensive than the ARGWELD® 'MKIII Purge Monitor' but as well as the expanded range, this model has switch able alarm set points for high and low levels to activate a warning light, buzzer, klaxon, ventilator, valve and so on. The ARGWELD® 'MKIII HR', high resolution version of the 'MKIII', with the range of the 'Purge Alarm', but no alarm/set po    











The Argweld ® Titanium Purge Monitor has been specifically designed for indicating oxygen levels in Argon gas for weld purging.
It measures and clearly indicates actual oxygen levels in parts per million down to 10 parts per million on an alpha-numeric display. The Argweld unit is menu driven by four buttons on the front panel and has an internal alarm with high and low oxygen levels which can be set on the front panel. A unique new Argweld sensor is used which has very little maintenance requirement and tests have shown that it should last up to  five years.  An optional software package is available to allow a computer to be used to store and print results and graphs etc for quality control purposes.FeaturesSmall, light, portable and inexpensive.Automatic fault finding diagnostics.Measures and indicates down to 10ppm.Unique fast response sensor with extended 5 year life.Optional Purge Log 2000 Software for data acquisition.Specially developed for weld purging of titanium.Low repair, refurbishment and recalibration costs.Operation with orbital welders and welding enclosures.Ideal for welding stainless steel in ultra clean applications.Internal alarm and security pin code facilities.Push button operated menu.No pumps or moving parts.Weld start/stop facility. 
SpecificationOperating voltage 115/230 v single phase  50/60hz.Computer interfacePurge Log 2000 Data Logging Software (optional).User interface for external alarm, high/low ppm settings, on/off welder switching, etc.Operating buttons sealed  to IP65 standard.Two minute warm up time.Switchable facility for readings in ppm or percentage.RS232 port for PC.Power consumption 18wint features.  Information Afterwards, the bladders are deflated and the device easily removed.This uniquely designed system means that only one inlet is required for both bladder inflation and introduction of the purge gas. The relief valve can be set to work at any desired flow up to 20 liters/minute and can be set to inflate the bladders and purge the interspaces simultaneously every time. Information
