Monitor your Titanium Welds for High Quality Results

Preventing oxidation when welding tubes and pipes can be achieved by purging the inside with an inert gas. This simple procedure saves both time and cost. By knowing the exact level of oxygen inside the pipe at all times, the welder knows when to start welding for high quality results. With restricted budgets in mind, […]

Pipe Purging accurately down to 10 ppm

Measuring the oxygen level during Pipe Purging is crucial. Stainless steel has to be monitored down to at least 100 ppm, however alloys such as titanium and zirconium may need to be monitored down to as low as 10 ppm. Pipe Purging Experts Huntingdon Fusion Techniques HFT®’s PurgEye® 200 Weld Purge Monitor® will ensure zero […]

Successful Low Cost Weld Purging

Weld Purging is the act of removing oxygen from the vicinity of a joint before, during and after welding. Metals that require weld purging include stainless steels, titanium and zirconium. Weld Purging various sizes of tubes and pipes can be challenging as well as expensive, which is why many welders today continue to construct their […]

Oxide Free Titanium Welds with the PurgEye® Desk

The Welding Institute states that “Titanium is a reactive metal; it will burn in pure oxygen at 600°C and in nitrogen at around 800°C. Oxygen and nitrogen will also diffuse into titanium at temperatures above 400°C raising the tensile strength but embrittling the metal. Despite this reactivity titanium is used extensively in chemical processing, offshore […]

Pipe Freezing for Quick Pipe Repairs

Avoiding the requirement to drain down pipelines for repair work or to carry out maintenance can save a considerable amount of time and potential loss of product. Qwik-Freezer™ Pipe Freezing System eliminates the need to drain pipework by creating a freeze plug. Available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT® Qwik-Freezer is a […]

Unique, all in one, 10 ppm Weld Purge Monitor®

Metals that are classed as reactive are sensitive to oxygen when they are heated, therefore the oxygen must be purged from the welding zone before, during and after welding. When welding reactive metals such as titanium, zirconium and nickel alloys, it is therefore important to monitor the oxygen level before, during and after welding. Weld […]

Heavy-Duty Pipe Blocking with Steel Plugs

Heavy-duty pipe blocking and stopping is easy with the Steel Plugs Range from Pipestoppers®. Pipestoppers®, a division of Huntingdon Fusion Techniques HFT®, manufacture Steel Plugs, which have been the favoured heavy-duty plug for applications such as leak testing, pipe stopping and blocking for their sealing effectiveness and durability. HFT Pipestoppers® Steel Plugs can be used […]

Precise Tungsten Electrodes Tips with the TEG-1000

Correctly preparing each Tungsten Electrode for welding is crucial. It is one of the most important variables in TIG / GTA welding and each Tungsten Electrode must be ground properly to improve arc starting, stability and subsequently weld quality. Manufactured with a diamond wheel, the TEG-1000 Tungsten Electrode Grinder from Huntingdon Fusion Techniques HFT® will […]

Weld Purging CMV Steels

CMV Steels (chromium / molybdenum / vanadium) are widely used for their high temperature creep properties especially in the steam turbine industries. Both pre and post weld heat treatment is necessary to achieve the optimum mechanical strength, but temperatures up to 300ºC (572ºF) must be maintained for lengthy periods. To prevent oxidation, the inside of […]

Low Cost Weld Purge Dams

Weld Purging short pipe pieces and dome-end welds where tandem Inflatable Tube and Pipe Purging Systems are unsuitable, Huntingdon Fusion Techniques HFT® manufactures Weld Purge Dams. Ron Sewell, Chairman for HFT® said: “When welding tubes and pipes, the most cost- effective solution is to restrict the volume, usually with a Tandem Weld Purging System, especially […]

High Temperature Weld Backing Tape®

Supporting the liquid weld root with a high temperature Backing Tape will ensure minimal oxidation and will require much less post-weld cleaning. Argweld® glass fibre Weld Backing Tape® from Huntingdon Fusion Techniques HFT® supports weld roots and eliminates the creation of slag, whilst removing contact with air to dramatically reduce the amount of contamination. Ron […]

Premium Quality Rubber Plugs

Lightweight Inflatable Rubber Plugs are available from the Pipestoppers® Division at Huntingdon Fusion Techniques HFT® for sealing, stopping and blocking pipes where oils, hydrocarbons and petrochemicals are present. Challenging pipe stopping conditions can cause major inconveniences but many alternative products are not able to handle such situations. Luke Keane, Technical Sales Manager for HFT® said: […]
