Pipe Plugging with a Difference

02-AccuFreezeThe Pipestoppers® Division of Huntingdon Fusion Techniques, HFT®, continues to grow with the addition of two new product ranges.

For making repairs to pipes with fluid inside, the Qwik-Freezer® and Accu-Freeze® Systems have been introduced. Freeze sealing is an increasingly popular alternative to “hot-tapping” and eliminates the need to shut down or drain down a system for repairs and maintenance.

These systems work by creating ice plugs (or “freeze seals”) either upstream of the repair site or on either side of an area where a pipe system needs to be maintained, for example, where a valve has to be replaced or a section of pipe needs to be cut out or where a leak has to be fixed.

No matter what the size of pipe or the fluid that is inside, one of the two models will most likely be suitable.

The Qwik-Freezer® System uses liquid carbon dioxide and a series of insulated freeze jackets to wrap around the pipes to freeze the contents inside the jacket. Accu-Freeze® uses liquid nitrogen with either copper coils wound around the pipe or with aluminium “clam-shell” style LN2 freeze jackets that are bolted together around the pipe.

Weld Purging Provides the Cleanest, Highest Quality and Lowest Cost Welds Ever!

01W-PurgEye100-IP65-WeldPurgeMonitorWeld 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.held, battery driven PurgEye® 100, monitors oxygen levels from atmospheric level (20.94%) down to 100 ppm (0.01%).

With over 40 years of innovation, design and manufacturing experience, Huntingdon Fusion Techniques HFT®’s hand held, battery driven PurgEye® 100 IP65, 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 IP65 Weld Purge Monitor® is now a fully accredited IP65 standard rated instrument that can be used out on site, in rainy and dusty conditions.

QuickPurge® High Speed Pipe Purging System… Time is money!

10W-QuickPurgePipeWeldPurgeSystemWaiting for pipe joints to be purged ready for welding can take anything up to four hours, depending on the diameter of the pipe being welding and the method chosen for purging.
QuickPurge® III cuts these waiting times so dramatically that they amortise themselves in less than one weld.

A 36” diameter stainless steel pipe for example can be purged down to 100 parts per million (ppm) of oxygen in under 32 minutes. Compare this with purging using foam dams that will outgas heavily into the weld zone and will take hours, not a few minutes.

High speed pipe purging system QuickPurge® is leading the way in the field of purging tube, pipe and pipeline joints over 6” diameter, where oxygen levels are required to be as low as 10 (ppm) or less.

Huntingdon Fusion Techniques, HFT®‘s innovative design of the QuickPurge® System means that zero colour welds will be achieved and there will be no loss of corrosion resistance caused by oxidation.

PurgEye® 200 IP65

03W-PurgEye200-WeldPurgeMonitorDeveloped for the process industries the portable PurgEye® 200 IP65 Weld Purge Monitor® meets the needs of higher welding specifications requiring oxygen levels down to 10 parts per million (ppm).

Weld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds.

Huntingdon Fusion Techniques HFT®’s hand held, rechargeable battery driven PurgEye® 200 IP65 model is totally waterproof and dustproof, has warning icons appear on the large screen to show low battery, low sensor conditions and also displays oxygen readings in % or ppm very accurately down to 10 ppm.

It is probably the lowest cost Weld Purge Monitor® of its kind even though it contains an internal electromechanical pump for drawing samples of purge gas automatically over the sensor before discharging it to the atmosphere.

The long life sensor eliminates the need for changing cells once every year or so, as is the case with wet cell instruments.

Argweld® Weld Purge Dams

06W-InflatableWeldPurgeDamsFor closure welds, tight bends, T piece joints, dome end connections and so on, where a conventional Tandem Weld Purging System cannot be used, a range of low cost, single ended Inflatable Weld Purge Dams are available from Huntingdon Fusion Techniques HFT®.

Manufactured for pipe diameters from 6 to 88 inches (152 mm up to 2,235 mm), these lightweight systems are easy to inflate using the purge gas.

Once the Dam is inflated and seals all around the internal circumference of the pipe, the excess inert purge gas spills out and purges the space around the weld joint which then pushes the air out to the open atmosphere.

Each Dam is equipped with a purge/inflation hose (black), an extra purge gas hose (blue) as well as a hose for connecting a Weld Purge Monitor® (red).

Upgraded High Speed Pipe Purging System

Quick Purge Rapid Fast Purging Inflatable Tube Pipe Pipeline Weld SystemsAn upgraded Pipe Purging System has been introduced for High Speed Pipe Joint welding, by Huntingdon Fusion Techniques, HFT®. Stocks of QuickPurge®III are available for delivery world wide.

Using IntaCal® II combined with the integrated PurgeGate® device,makes it possible to safely inflate the dams with argon gas, prior to releasing it for purging the space between the dams where the weld joint is located.

It is almost impossible now for the inflatable dams to burst as a result of undue pressure increase or accidental flow increase of the inflation and purging gas.

Continuing the constant development of products Huntingdon Fusion Techniques, HFT® has launched this new upgrade of the QuickPurge® II system.
