HotPurge™ Pipe Purging Systems for pre-heated Pipe Welding

HotPurge Pre Heated Pipework Purge SystemsThick wall chrome steel pipe joints, as used in the power industry for high pressure high strength pipe work, need to be pre-heated for welding and probably need a post weld heat treatment too.

Weld joints of this nature need to be purged of oxygen and welded in an inert gas atmosphere, to prevent oxidation, slag formation etc., that leads to loss of corrosion resistance and undesirable change to the metallurgy.

With the high temperatures and length of time at temperature needed in the pre-heat, weld and post heat treat cycles, most weld purging systems are unsuitable.

However, Huntingdon Fusion Techniques, HFT®, has now developed "HotPurge™" Pipe Purging Systems, for use up to 300ºC (572ºF) for 24 hours. (The material used is rated up to 700ºC (1,292ºF)

New Training Courses

Weld Purging Best Practices for the Nuclear Industry.

Weld Training Courses Welding Equipment Purging Products

With the growth of Nuclear Power activities around the world, there will be a large volume of stainless steel pipework that will need to be welded.

The pipe joints will need to be started with a much higher weld purge quality than many operators are familiar with and those welds will need to be planned well in advance to consider the joining and purging methods.

Until now, weld purging has often been left to the last minute as a procedure that the operators deal with at the time.

This can lead to the use hastily home made devices that will bring contamination into the nuclear environment and difficulties in accessing spaces for satisfactory weld purging.

Return on Investment QuickPurge®II

1 QuickPurge Pipe Weld Purge SystemFor a stainless steel pipe welding job with just under 17,000 joints from 6 - 36" diameter, it was found that a gas savings of almost 7 million litres of Argon were made, when comparing old fashioned weld purging products with modern day products like the QuickPurge®II System.

A return on investment document has been created showing savings, weld by weld, so that operators can extrapolate to make their own calculations.

With such dramatic savings, operators can apply their own Argon or Helium gas costs to assess the

savings that they could make with the QuickPurge®II system.

The full ROI (Return on Investment) analysis document is available on request from Huntingdon Fusion Techniques HFT®.

Argweld® QuickPurge® II

33W-QuickPurgePipeWeldPurgeSystemCoinciding with Fabtech 2013 in Chicago, Huntingdon Fusion Techniques (HFT®) is launching the most revolutionary Pipe Weld Purging System ever QuickPurge® II.

The original QuickPurge® concept was devised between HFT® and Mitsui Babcock just over ten years ago for the isle of grain stainless steel pipeline across the south of England.

Now, after the phenomenal success of this concept of weld purging, HFT® has added a whole new raft of improvements:

PurgeGate®:

Probably the most significant development ever for inflatable weld purge systems is PurgeGate™.

This extremely clever device will prevent the inflatable dams from ever bursting due to over inflation or over pressurisation.

Why should you use Inert Gas Purging when welding Stainless Steel, Titanium and Nickel Alloys?

Why should you use Inert Gas Purging when welding Stainless Steel, Titanium and Nickel Alloys? 

1. PurgEliteWeldPurgeSystems

Preventing oxidation and thus avoiding discolouration and weld underbead discontinuities in tubes and pipes can be achieved readily by purging the inside with inert gas. This simple procedure saves both time and cost, both of which can be considerable. Consider the thoughts of one specialist;

 'It's difficult persuading our supervisors to allow us to take the time to purge lines during the welding process! Instead, engineers weld the lines, then use a die grinder with a flapper wheel to clean the "grapes" off the inside of the pipe! What an incredible waste of time.

Purging really makes more sense in the long run, especially since products going through these lines get snagged or contaminated.

The troubleshooting process is confused because the pipe fitter may not see the correlation, nor does the machine operator unless there is good exchange of information!'

Launch of new Tube and Pipe Weld Purge Systems™

QuickPurge Pipe Weld Purge SystemThe PurgEye® 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.

Along with other recently announced scientific developments in its Weld Purge Monitor® series, 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 from the very highly specialist Biogas and Semiconductor fields, right along to other industries such as those where the pipework is less critical.

In particular, 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.

Return on Investment

Argweld® Pipe Purging Systems and Argweld® PurgEye® Weld Purge Monitor® Offer Tremendous 'RETURN ON INVESTMENT' (ROI)

PurgEye100 IP65 Weld Purge Monitor

Argweld® PurgEye® and Weld Purge Monitors® together with PurgElite® and Quick Purge® Inflatable Pipe Purging Products usually pay for themselves in the first one or two days.

These great products offer thousands of Dollars in savings over the course of a job.

A huge Return on Investment (ROI).

Have a look at the great savings!

Reduced purge time means reduced man-hours (labour costs / overhead)
Example: Welding 10" SS pipe

  • Normal time required to purge 10" pipe is usually 45 minutes or more per weld.....
  • Purge Time with Quick Purge® is about 3 minutes...
  • Quick Purge® systems would conservatively save 30 minutes of labor PER WELD

If the job involves (20) 10" joints (welds) the Weld Purge Monitor@ products would save 10 man-hours.

If the job involves 100 welds there would be a saving of 50 man hours.
