Weld purging provides the cleanest,
highest quality and lowest cost welds ever!

Weld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds by monitoring the oxygen level when welding metals such as titanium, stainless steels and nickel alloys where a high quality weld is required.

By striving for zero colour welds, companies can eliminate the post weld cleaning costs, which can be very high, making the cost of each weld ultra significant.

With over 40 years of innovation, design and manufacturing experience, Huntingdon Fusion Techniques HFT®'s hand held, battery driven PurgEye® 100, monitors oxygen levels from atmospheric level (20.94%) down to 100 ppm (0.01%).

Advancing the science of manufacturing beyond other designs, the PurgEye® 100 Weld Purge Monitor®¹ is now a fully accredited IP65 standard rated instrument that can be used out on site, in rainy and dusty conditions.

This advanced model is equipped with a push button 'auto calibration' feature, which allows the monitor to be calibrated both at atmospheric level (20.94%) and again at 100 ppm, to ensure the accuracy of oxygen levels for quality results.

The newly designed, extra long life sensor allows the user to continue to use the monitor for up to three years before the 'new' low sensor indicator appears on the screen. Once that icon appears, it provides the user with adequate time to obtain a new sensor, which can be fitted on site without any complicated electrical wiring to change, thereby saving the operator from having to return it to the manufacturer for recalibration and saving the equivalent of 50% of a new monitor.
It pays to buy the best!

The improved one piece probe assembly is a significant advantage over other models that can leak oxygen, thus distrorting readings.

The PurgEye® 100 has a clear, easy to read LCD screen, offering a 24 mm high display, which is approximately a 41% larger display than the ones used by other instruments. The display also shows a low battery icon as well as the low sensor icon already mentioned.

When the Weld Purge Monitor® is not in use, an automatic sleep mode will activate to conserve battery life.

Quick connect / disconnect, leaktight fittings are an advatage for gas purge tubing. A tripod mount is integrated in the housing, to ensure the Weld Purge Monitor® can be located securely in an accessible viewing position without having to resort to additional clamping fixtures.

The PurgEye® 100 Weld Purge Monitor® is shipped in a new, low volume ergonomically designed, attractive, more robust carry / presentation and storage case to maintain the instrument in good condition and and keep it together with all accessories.

This model can be used with any tube or pipe weld purging system, any weld chamber or weld purging enclosure.

Ensure your Weld Purging System doesn't
over-inflate by using a PurgeGate® Valve

Many Inflatable Tube and Pipe Purging Systems are at risk of over-inflating during the weld purging process.

As the heat of welding rises, the inflatable dams can expand beyond their safe limits and in addition, other personnel working near the welding area can vary the gas flow or pressure at random causing over inflation and bursting.

Once a burst occurs, the purge is lost and the weld will immediately oxidise in the presence of incoming air. The welder will then have to cease welding, grind out the oxidation and then start the whole process again.

To prevent such bursts, Huntingdon Fusion Techniques HFT® has designed and now manufactures a PurgeGate® Valve System in order to prevent any over-pressurising of Inflatable Tube and Pipe Purging Systems.

These devices, which are fitted as standard on the HotPurge™ and QuickPurge® Systems (PurgeGate II), are offered as accessories for the PurgElite®, PurgExtra™ and any other manufacturers versions of Inflatable Tube and Pipe Purging Systems.

They have an easy push fit connection and are simply, plug and play. The PurgeGate® Valves fit all system sizes, from 1" to 96" and can be moved from system to system.

Inflatable Pipestoppers, where
access to the job site is difficult

Blocking pipes for purging or to carry out routine maintenance can be much easier with an Inflatable Pipestopper.

A range of standard and non-standard Inflatable Stoppers for tubes, pipes, pipework fabrications and ductwork is available from the Pipestoppers® Division of HFT®.

These versatile Inflatable Stoppers are used to service a wide variety of industrial applications. As "overnight stoppers" they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during down time.

In machining applications, they can be inserted below a horizontal flange on a vertical pipe, to prevent machining fluid from falling below into expensive machinery such as pumps and turbines etc.

When welding large tanks and vessels, stoppers inflated with air can dramatically reduce the volume inside, so that the argon purging process takes little time and uses the minimum of expensive gas.  The stoppers pay for themselves in one weld and can be used multiple times.

Other applications include leak testing of pipework systems, whether commercial, domestic or industrial, on site thermoforming of bends in plastic materials and fiber-optic constructions projects.

All Inflatable Stoppers are manufactured with a strong internal inflatable bag covered in waterproof sewn polyurethane coated nylon for low friction and to prevent the production of static electricity or accidental sparking.

Inflatable Stoppers are particularly useful when inserting into a small opening close to a job site, rather than at the end of the pipe. No high-pressure equipment is needed for inflation.

The standard range of HFT®'s Pipestoppers® Inflatable Stoppers are available for immediate delivery in cylindrical or spherical formats with sizes ranging from 1 to 96" (25 to 2440 mm).

Inflatable Stoppers are also available with heat resistant covers to protect them against high temperatures.

HFT® also has a range Rubber Inflatable Stoppers that are suitable for petrochemical applications and are resistant to all hydrocarbon fluids and gases.

Keep a Distant 'Eye' on your Purge

When welding lengths of tubes and pipelines over 20 metres long, one problem operators face is not receiving a fast and true weld purge reading from the purge zone.

Now, for the first time, it is possible to have an immediate reading of the weld purge gas at the underside of the joint, from any distance up to 1,000 metres away.

By using a zirconia sensor in a remote module placed at the purge gas exhaust, really close to the weld, it is possible to instantaneously receive actual oxygen readings down to 10 ppm (0.001%) up to 1,000 metres away.

This technology is part of the PurgEye® 1000, the latest in the Family Range of Weld Purge Monitors® brought to the marketplace over the last few years by Huntingdon Fusion Techniques HFT®.

The Weld Purge Monitor® was invented by Huntingdon Fusion Techniques HFT® in the 1970's and the company now has a Registered Trademark protection in the USA and Europe.

If exhaust gas from a normal weld purge system is piped down a hose to a distant measuring instrument, it may take many minutes, or even hours in some cases, to reach the sensor. The exhaust gas may even be contaminated on the way by outgassing from the walls of the hose material or from air drawn in through a leaky connection.

The PurgEye® 1000 Weld Purge Monitor® has been designed and developed specifically to overcome such difficulties and has a sensor placed immediately next to the weld purge site.

The sensor is secured in a tiny module and is connected to the measuring instrument by a data cable. The purge reading is sent back to the instrument at the speed of light, so operators and quality control personnel know immediately whether the purge is satisfactory.

This way, the operator can be certain that the weld purge reading is correct and that the joint will not be adversely affected by oxidation, allowing welders to achieve that sought after zero colour weld.
