Safe Pipe Repair with Accu-Freeze™

Pipe freezing for temporary pipe isolation has now become the safest, quickest and most cost-effective method for pipeline leak testing, maintenance work or for making pipe repairs including valve and other control system replacements. It is still very common for maintenance workers to drain down entire systems before repairs can be made but this can […]

Pressure Testing Pipework up to 6 Psi with Inflatable Stoppers

Vessels such as pipelines, gas cylinders and fuel tanks are often pressure tested for strength and leaks. A range of standard and non-standard Inflatable Stoppers for tanks, chambers, tubes, pipes, pipework fabrications and ductwork is available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®. Ron Sewell, Chairman for HFT® said: “Our range of Inflatable […]

Low Cost Weld Purge Monitor for Welding Titanium

Weld Purging Techniques are now used in most industries especially when welding reactive metals. Whilst the welding torch provides a protective cover to the top of the fusion zone, inert gas coverage is also required at the weld root. By sampling the gas and testing the oxygen content around the weld, the welder knows when […]

No Burst Pipe Purging Systems with PurgeGate

Pipe welders are now turning more and more to Inflatable Pipe Purging Systems because of their easy use to complete a weld faster and with less risk of oxidation, to save money from the speed and the avoidance of reject or cut outs. These unique systems restrict weld purging zones, saving time waiting for pipes […]

High Quality Feed Hose for Inert Gas Supply

Using a high quality gas welding hose will ensure a leak tight method of feeding non-contaminated gas into the welding zone for weld purging. Continuing their pursuit to advance in Weld Purging Technology, Huntingdon Fusion Techniques HFT® now manufacture tailor made Inert Gas Feed Hose assemblies with leak tight fittings and a low outgassing rate. […]

Portable 10 ppm Weld Purge Monitor

With ever-improving standards in Quality Control, measuring the oxygen level around welds before, during and after welding reactive metals is crucial. The hand held PurgEye® 200 is a Weld Purging Monitor® specifically developed and designed for use when welding titanium, zirconium, high specification stainless steel and nickel alloy joints, so that the user can produce […]

Weld Purging: Replace Foam with Film for High Quality Welds

The use of home made sponge foam purge dams for pipe weld purging is still very familiar throughout the welding industry. However, operators are unaware as to how the use of sponge foam can adversely influence the metallurgical strength of a joint. When sponge foam starts to warm up from the heat of the weld, […]

Zero Colour Titanium Welds with the PurgEye® Desk

Titanium is the metal of choice in a variety of industries due to its excellent corrosion resistance to acids, chlorides and salt. Titanium has a wide continuous service temperature range, from liquid nitrogen (-322°F) to 1,100°F and the highest strength-to-weight ratio of any metal. Titanium is a reactive metal, so when heated it will react […]

No Draining the Pipe System with Pipe Freezing

Eliminating the need to drain long sections of pipe for repairs or modifications and reducing shut down time is now possible with Pipe Freezing Systems. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides a cost saving solution with Qwik-Freezer™, the industry standard portable CO2 Pipe Freezing System. Ron Sewell, Chairman for HFT® said: “Pipelines […]

New: Unique 10 ppm Colour Touch Screen Weld Purge Monitor®

It is essential to monitor the oxygen level when welding reactive metals. Metals that are classed as ‘reactive’ (titanium, zirconium and nickel alloys) are sensitive to oxygen when heated. When welding these metals, the oxygen must be purged from the welding zone, down to as low as 10 parts per million (ppm). Weld Purging in […]

Heavy-Duty Flow and Line Stopping with Steel Plugs

There are occasions where pipes need to be repaired whilst liquids are still flowing. Heavy-duty flow stopping and line plugging may require plugs and stoppers to have long immersion in chemicals or exposure to high temperatures, which many such items are not capable of withstanding. Providing the user with the opportunity to isolate a section […]

Improve Tungsten Electrode and Welding Arc Performance with the TEG-1000

Tungsten Electrode Grinders are essential with TIG/GTA welding. Using a Grinder that has been designed and manufactured specifically for tungsten metal is not only a much safer option, they provide more accurate results leading to as many as ten times greater number of arc strikes and giving very directional arcs without flicker or wander. The […]
