Purging Large Stainless Steel Pipes

Restricting the volume when welding large stainless steel tube and pipes can save huge amounts of time and inert gas costs. Previously, welders have spent many hours waiting for oxygen levels to be low enough to start welding. Leading the way in Weld Purging Innovation and Technology, Huntingdon Fusion Techniques HFT® have designed and developed […]

Liquid Nitrogen Pipe Freezing

Pipe freezing is a simple and efficient way of sealing a pipe or system while pipe repairs or general pipework maintenance is carried out, without the need to drain the system. Accu-Freeze™ Pipe Freezing Systems are available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®. Accu-Freeze™ works by reducing the pipe fluid to a […]

Flow Stopping Solutions for all Applications

Flow and line stopping equipment gives the user the opportunity to isolate a section of pipeline to carry out repair and maintenance work. The Pipestoppers® Division from Huntingdon Fusion Techniques HFT® design and manufacture a Range of standard and non-standard Inflatable Stoppers for tanks, chambers, tubes, pipes and pipework fabrications, offering a range of pipe […]

QuickPurge Pipe Purging

Pipe Purging: Purging large diameter pipework ready for welding can be expensive. Without restricting the volume, there is a high cost involved in inert gas used and time spent waiting for the oxygen level to reach a level low enough for welding to begin. Weld Purging experts Huntingdon Fusion Techniques HFT® have designed and developed […]

Argon Regulator for Pipe Purging Systems

Dramatic savings can be achieved when welding stainless and chromium steels and also titanium alloy tube and pipes with the use of an Inflatable Pipe Purging System. By restricting weld purging zones, Inflatable Pipe Purging Systems achieve a huge saving in time waiting for pipes to be completely filled with argon, purged down to a […]

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 […]

Weld Backing Tape

Weld Backing Tape supports weld roots and eliminates the creation of slag, whilst removing contact with air to dramatically reduce the amount of contamination. Here are some of our Frequently Asked Questions! Q. Does the Argweld® Weld Backing Tape® support the weld? A. Yes, Argweld® Weld Backing Tape will support the weld pool for a […]

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 […]
