Disruption Free Pipe Repairs with Pipe Freezing

Companies facing system downtime can drastically reduce pipe and valve repair and maintenance costs with Accu-Freeze™ available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®.

Many companies may have pipework systems such as sprinkler systems for example, that are full of water or other fluid that need to be completely drained for the smallest of repair.

Companies facing system downtime can drastically reduce pipe and valve repair and maintenance costs with Accu-Freeze™ available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®.

Luke Keane, Technical Support at HFT® said: “We carried out an installation of an Accu-Freeze™ System for a client who was contracted to repair pipework in large blocks of apartments. Working in the plant room, access was pretty tight as the pipes were only 6 – 8” from the ground. At one end of the pipe there was a pressure gauge and at the other, a 1,000 litre hot water cylinder. Ambient temperature in the pipe was approximately 38ºC.”

Low Cost Weld Purge Monitoring down to 10 ppm

Using the latest scientific knowledge and innovation, Huntingdon Fusion Techniques HFT® have designed and manufactured the PurgEye® Nano, the World’s first and only low cost, no frills, Weld Purge Monitor® that measures accurately down to 10 parts per million (ppm).

For many years, oxygen monitors and gas analysers have been used for weld purging. They are specifically designed and calibrated for accuracy at atmospheric oxygen level but not for weld purging where accuracy is required when reading much lower oxygen levels.

Using the latest scientific knowledge and innovation, Huntingdon Fusion Techniques HFT® have designed and manufactured the PurgEye® Nano, the World’s first and only low cost, no frills, Weld Purge Monitor® that measures accurately down to 10 parts per million (ppm).

Ron Sewell, Chairman for HFT® said: “A Weld Purge Monitor® is essential to monitor oxygen levels when welding metals such as stainless steels, titanium and nickel alloys where a high quality, non-oxidised, zero colour weld is required. The PurgEye® Nano has been developed for weld purging where data logging, alarms and welder control are not necessarily required. It is small, lightweight and inexpensive. There are no knobs, no switches, no controls, making this a really simple, ‘plug and play’ monitor.”

Large Diameter Pipe Purging

Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative QuickPurge® Systems, which are manufactured up to 88” (2,235mm), dramatically reduces the space that needs to be purged, thereby reducing purging time dramatically, making huge savings in both time and gas costs.

Care is necessary when welding large diameter pipework in stainless, duplex, chrome steels, nickel alloys and zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding, which can cause a huge expense when they are of a large diameter.

Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative QuickPurge® Systems, which are manufactured up to 88” (2,235mm), dramatically reduces the space that needs to be purged, thereby reducing purging time dramatically, making huge savings in both time and gas costs.

Ron Sewell, Chairman for HFT® said: “Using QuickPurge® means there is no longer a need to fill complete pipes with an inert gas. The systems are so efficient they pay for themselves in the first couple of welds in gas savings alone, whatever the pipe size. QuickPurge® is simply inserted into a tube or pipe, inflated within the pipe, restricting the area that is to be welded, reducing the oxygen level down to 100 ppm (parts per million) within minutes.”

Weldability of Grade 9 Titanium Alloy

Recognising both the performance requirement and the health benefits, Huntingdon Fusion Techniques HFT®’s MultiStrike® Tungsten Electrodes not only deliver an increased overall performance, they also contain a mix of non-radio-toxic compounds.

The increasing popularity of Grade 9 titanium alloy has brought with it some questions about weldability.

Grade 9 titanium alloy contains 3% aluminium and 2.5% vanadium, less alloying material than the more common Grade 5 (6% aluminium and 4% vanadium). Grade 9, alternatively referred to as Ti-3-2.5, offers improved resistance to corrosion and better mechanical strength and is now routinely used in applications as diverse as aircraft hydraulic tubes and high specification bicycle frames.

Weldability of Ti-3-2.5 is good provided that the necessary precautions are taken. Due to the reactive nature of titanium and its alloys, inert gas shielding must be in place on both the OD and ID of tubes and protection assured when welding plate and sheet.

Improved Performance when using MultiStrike® Tungsten Electrodes

Recognising both the performance requirement and the health benefits, Huntingdon Fusion Techniques HFT®’s MultiStrike® Tungsten Electrodes not only deliver an increased overall performance, they also contain a mix of non-radio-toxic compounds.

Tungsten Electrodes are used during Tungsten Inert Gas (TIG) or Plasma welding and are the most important consumable during welding. However they are often manufactured using thoria, dust from which poses a risk to health.

Recognising both the performance requirement and the health benefits, Huntingdon Fusion Techniques HFT®’s MultiStrike® Tungsten Electrodes not only deliver an increased overall performance, they also contain a mix of non-radio-toxic compounds. These MultiStrike® electrodes give at least 10 times more arc striking capacity than alternative electrodes tested under the same conditions.

MultiStrikes® can be used for welding aluminium with the AC process, as well as steels and alloys with the DC process, which allows the welder to have just one type of Tungsten Electrode to weld all materials and reduce the amount of stocks and purchasing requisitions.

Portable Pipe Freezing System

Pipe Freezing Experts Huntingdon Fusion Techniques HFT® has introduced the Qwik-Freezer™ Systems to their Pipestoppers® Division. These systems use CO2 to create ice plugs or freeze seals in the pipes, avoiding the requirement to completely drain down systems.It is often very challenging to carry out repair work on pipes containing liquids. One option to carry out this maintenance is to completely drain the system, which can prove costly.

Pipe Freezing Experts Huntingdon Fusion Techniques HFT® has introduced the Qwik-Freezer™ Systems to their Pipestoppers® Division. These systems use CO2 to create ice plugs or freeze seals in the pipes, avoiding the requirement to completely drain down systems.

Luke Keane, Technical Sales Manager for HFT® said: “Temporarily isolating the water in a system with CO2 Pipe Freezing Qwik-Freezer™ allows for repairs or modifications to be made without draining or shutting off the system, saving time, wastage and is quick and easy.”

A specially designed jacket is wrapped around the pipe at the point where the freeze is required. A nozzle on the jacket is then coupled to a cylinder of liquid CO2 by means of a high-pressure hose. When the liquid CO2 is injected into the space between the Qwik-Freezer™ jacket and pipe, it immediately reduces the temperature inside the Qwik-Freezer™ jacket to -78ºC (-109ºF) and this is transferred rapidly to freeze the pipe contents and thus seal the volume.
