Launch of Argweld Pipe Weld Purging Systems® for tube, pipe and pipeline industries

PurgElite® systems (All 6 sizes)
PurgElite® systems (All 6 sizes)

Having been manufacturing Tube and Pipe Weld Purging Systems since 1975 Huntingdon Fusion Techniques HFT® has evolved the science of Weld Purging to new levels.

The Company has now reached the fifth version of its Tube and Pipe Weld Purge System designs by launching the new PurgElite® range of Tube and Pipe Weld Purging systems for diameters from 1" to 24" diameter inclusive. These systems are suitable for all industries using tubes and pipes.

In particular, however, PurgElite® systems can be used in high quality tube and pipework where the internal surfaces may be polished to ensure minimum entrapment and low corrosion resistance.

With the new Intacal® specially designed in line purge valve and the synthetic hose protection, there are no metal parts to scratch the tube or pipe surfaces.

IntaCal® needs no setting or controlling, but is precisely manufactured for the PurgElite® method of weld purging.

This new range comprises 15 models for tube and pipe sizes from just under 1" to 24", each one overlapping the range of the other so that all internal diameters from 20 mm up to 610 mm are covered.

The new series has a number of major advantages over previous weld purging systems and has taken into account the evolving technology in all market places where much higher specifications of materials and work finish are available and expected.

The groundbreaking key feature is PurgeGate™

PurgeGate™ is a world wide patented device fitted to the front of each inflatable Purge System to protect it from bursting.

No matter how high operators turn up the pressure, it is impossible to cause the purge system to burst due to over pressurisation.

An amazing benefit to this device, is that the flow rate may be increased as desired without damage to the Weld Purge System. PurgeGate™ is guaranteed for life.

A. This leads to the advantages mentioned above, namely:

  • 1.0 The ability to manufacture a 1" system
  • 2.0 Absence of protruding metal parts that scratch the insides of electro polished tubes and pipes
  • 3.0 Elimination of the burst bladder problems that occur with other systems
  • 4.0 Faster purging using less of the expensive inert purging gas
  • 5.0 No complicated valve to set and to mis-function and no loss of time at the start up of jobs.

Other features of the PurgElite® system include:

  • B. High Tech, high temperature resistant, synthetic gas hose
  • C. Rootgo® Glow strip positioning band
  • D. Selection of Low Vapour Pressure Materials

Low Profile Valve:

1" diameter tube and pipe weld purging:

For the first time it is possible to locally purge 1" diameter tube and pipe welds with an inflatable tube and pipe weld purging system, instead of having to fill up complete systems with expensive inert weld purging gas.

The 1" PurgElite® Tube Weld Purging System will be a valuable welding accessory to manufacturers of many stainless steel, Titanium and Nickel Alloy tubular systems.

Absence of protruding Metal Parts:

No scratching: Particularly of expensive electro-polished tubes and pipes:

Weld purging is mostly carried out on Stainless, Duplex and Chrome steels as well as Nickel and Titanium alloys.

When internal tube and pipe surfaces are scratched by metal parts on old fashioned weld purging systems, there will be a loss of corrosion resistance that cannot readily be repaired.

Scratches cause interruptions to the flow of the gases or liquids inside and leave resting places where bacteria can multiply.

The PurgElite® system of Tube and Pipe weld purging systems, has eliminated the old style inflexible metal braided hose and substituted it for a new technology high temperature resistant, gas hose protector connecting the two purge dams.

The absence of protruding metal parts with the PurgElite® system completely minimises the risk of scratching and damaging the insides of valuable tube and pipe systems.

Manufacturers of High Purity Systems and those with some other critical applications will use internally electro-polished tubes and pipes making the PurgElite® system even more valuable and more essential to prevent scratching.

Elimination of burst bladder problems:

Other types of inflatable pipe purging systems have large valves that are often set incorrectly leading to frequent problems of burst bladders.

Operators will often think that they know and understand Pipe Purging Systems, so they will go ahead and set them up and proceed to burst bladders.

The new PurgElite® system completely overcomes that problem with a unique accessory for inflation and purging.

Faster Weld Purging:

With the smaller volume, simple gas release valve that uses mathematically calculated designs, the purge gas will be released faster and in greater quantities permitting fast purging of the volume below the weld, without creating the turbulence and long purge times associated with other devices.

When used with one of the PurgEye® Weld Purge Monitors® the PurgElite® systems provide the operator with the perfect combination to purge and monitor oxygen content to achieve the fastest and most ideal conditions for welding to begin.

The savings made by using less of the expensive inert purging gas, along with the savings achieved with shorter purging time, will help to pay for these products in just one weld.

No complicated valve to set and no loss of time at the start up of jobs.

The specially designed PurgElite® valve system allows operators to use their systems immediately without having to follow complicated valve setting procedures. Such work causes loss of production time and invariably leads to errors and failed systems.

The PurgElite® systems are totally and simply plug and play. Plug in the inert gas supply and purge the weld, more than halving set up time.

High Temperature resistant hose:

The heat build up in the welding cavity is such that the gas hose connecting the two dams has to have a high temperature resistance.

PurgElite® weld purge systems have a newly developed synthetic material capable of withstanding a temperature of 700 °C (c 1,300°F) that will withstand even hot metal dropping on it by building an intumescent layer.

The hose's intumescent properties make a heat barrier to prevent damage to the purge hose, thus avoiding the risk of loss of purge quality and the potential loss of a weld joint.

Rootglo® Replaceable Glo Strip band:

Once PurgElite® systems are inside a tube or pipe system, they can be pulled around from Joint to joint and positioned correctly and easily. This has been made possible by Rootglo® the fluorescent glo strip fitted to the centre of the purging system.

Rootglo® absorbs sufficient light during it's time in ambient conditions, to emit light inside dark spaces for up to 8 hours, so that the welders can see how their root welds are progressing.

Welders can see through the pipe joint into the internal dark area, whether clamped or tacked ready for welding and view the purge system as it comes into place, with the replaceable glo strip immediately below the weld.

Low Vapour Pressure Materials:

Employing latest material developments (HFT®) has selected lower vapour pressure materials to ensure that the outgassing rate into the weld zone will be reduced to the barest minimum during welding to protect the molten weld pool from oxidation and the problems arising.

For larger diameters of Pipes, Huntingdon Fusion Techniques® manufactures its rugged Argweld® Quick Purge® II Systems, also now fitted with PurgeGate™ and Rootglow® all aroun
