Purge your Tubes and Pipes the ‘Elite’ way

Purging Systems, Purge Bladders and Purge Dams, using real scientific purge bladder breakthrough technology, Argweld® PurgElite® Inflatable Tube and Pipe Weld Purging Systems introduces to the market place for the first time a ‘New’ 1 inch (25 mm) System for small diameter tubes and pipes. Another great innovation to help tube and pipe welders save time, money, gas and achieve better welds. The volume to purge is kept small, resulting in savings in both time and cost of inert gas used. Purge bladders and dams suitable for high quality pristine tube and pipe weld purging, 1 to 24″ (25 to 600 mm) diameters. For full technical information, use the tabs above.

Keep a distant ‘Eye’ on your Purge… up to 1 km away!

The World’s ‘first and only‘ remote Weld Purge Monitor®, measuring accurately down to 10 ppm. With an internal mechanical pump, all powered by the data cable from the display unit.

When welding joints in long tube line or pipeline sections, it is not normally practical to measure the purge gas exhaust close to the weld.

Measuring purge gas exiting in the joint gap is also unsatisfactory because of the heat generated in that area, the oxygen being drawn in from outside and other variable factors.

HFT® has developed an answer to this difficulty, namely a remote sensing head that can be fitted onto the purging system, directly at the weld location and will measure oxygen level in the purge gas and transmit the information electronically to the monitor up to 1 km away.

In 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.

PurgEye® a Family Series of Weld Purge Monitors®.

Purpose-designed Purge Monitor

The Argweld® PurgEye® 300 Nano Weld Purge Monitor® has been specifically designed as a very low cost, basic entry level version of the Argweld® PurgEye® 300 for indicating low oxygen levels in inert gas for weld purging down to 10 ppm.

With a large alpha-numeric display, the Argweld® PurgEye® 300 ‘Nano’ measures very accurately from 1000 ppm down to 10 ppm.

The Argweld® PurgEye® 300 ‘Nano’ uses a unique new low cost long life sensor which has very little maintenance requirement and avoids the disadvantages of monitors with ‘wet cell’ technology that have to be constantly calibrated and have sensors replaced.

Argweld® PurgEye® 300 Nano Weld Purge Monitors® are available for immediate delivery.

All this… in one Instrument!

t’s here, brilliant new technology, the best ‘Eye’ on your purge, at a stunningly attractive price! The Argweld® Purgeye® 600 Weld Purge Monitor® is the first computerised, colour touch screen, ‘State of the Art’ Weld Purge Monitor® to accurately read oxygen levels in the welding environment. This one monitor alone reads all the way from atmospheric concentration (20.94%) right down to 10 ppm.

Improve Weld Root Profiles!

Extending the HFT® range of products, we manufacture Argweld® Weld Backing Tape™, specifically for supporting weld roots and to provide very even weld root profiles.

The Weld Backing Tape™ comprises a 75 mm wide aluminium adhesive tape that has a 25 mm wide fibre glass band in the centre onto which the weld can be cast.

Welding speeds can be dramatically increased with the help of Argweld® Weld Backing Tape™.  The resulting weld is neat, clean and requires minimal post weld attention.
