Back Purging with Argweld® Weld Backing Tape®

Back Purging is the process of protecting and shielding the back side or under side of the weld during welding to prevent oxidation. Back Purging with fiberglass Weld Backing Tape® supports weld roots and can prevent oxidation, sugaring, achieving clean, oxide free welds. Luke Keane®, Technical Sales Manager for Huntingdon Fusion Techniques HFT® said: “We […]

Expanding Rubber Plugs for use with Oils, Hydrocarbons and Petrochemicals

Often, pipes containing oils, hydrocarbons and petrochemicals need to be blocked but not all plugs are suitable for such applications. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® manufacture a range of Rubber Plugs, for fast, reliable and safe pipe stopping. Ron Sewell, Chairman at HFT® said: “There are many applications where our Rubber Plugs […]

Distance Weld Purge Monitoring

GTA/TIG welding long pipelines made of stainless steel can be found in many different industries including Oil and Gas, Nuclear and LNG. The use of stainless steel can offer many advantages including corrosion resistant properties and cost-effectiveness of the alloy. With Stainless Steel being a reactive material, the oxygen in the protective gas must be […]

Save Time and Money with a High Quality Inflatable Purging System

When welding tubes and pipes made of alloys such as stainless, duplex and chrome, it is important to eliminate the oxygen internally with an inert gas. This will help prevent oxidation, discolouration and will ensure a good internal weld profile. Weld Purging long pipelines can be costly and time consuming, so restricting weld purge volumes […]

Weld Purging at a Low Cost

There are many occasions where Tandem Inflatable Tube and Pipe Purging Systems are not suitable and welders are often left to construct their own Weld Purging Equipment. Often, homemade purging devices are unsuitable and can often lead to loss of welds due to oxidation. Weld Purging Experts Huntingdon Fusion Techniques HFT® manufacture a range of […]

Eliminate the Thoria and Maintain the High Performance with Blue-Tipped MultiStrike® Tungsten Electrodes

Thoria, found in thoriated Tungsten Electrodes is a radio-toxic compound and emits mainly alpha particles, which are harmful if released inside the digestive tract or inside the lungs where they act as a carcinogen. Thoriated Tungsten Electrodes therefore pose a risk to welders during grinding. Why are thoriated Tungsten Electrodes still in use today? Welders […]

Welding Enclosures for Titanium Parts

Welding titanium alloys often has to be carried out in an environment where oxygen can be eliminated throughout the welding cycle. If the parts were to come into contact with oxygen ay any point, the reactive metal can become contaminated, oxidising which can lead to reductions in corrosion resistance and mechanical strength. Metal glove boxes, […]

Oxygen Monitor for Field Welding

Welding under site conditions introduces problems that are not found in normal factory environments. Exposure to heat and cold, sand and dust, damp and wet atmospheres place demands on standard Weld Purge Monitors® for which they are not designed to meet The PurgEye® Site, available from Weld Purging Experts Huntingdon Fusion Techniques HFT® is protected […]

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 […]

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 […]
