Food and Beverage Industry Tubes and Pipes Benefit From Better Welds

When tubes and pipes in the Food and Beverage Industry are welded, it is vital that they are free from oxidation and discolouration. Welds that are not free from heavy oxidation may protrude into the pipe and create traps where product may build up over time and which could contaminate the product moving through the […]

On-Site Weld Purge Monitor® for the Petrochemical Industry

Welding within the Petrochemical Industry involves working in refineries and plants that produce gasoline and a variety of other petroleum-based products as well as chemicals and oil-related products. Welded joints in these applications are often critical and the insides of pipework must be purged with expensive argon gas to reduce the oxygen levels around the […]

Weld Purging of Pipes for the Oil and Gas Industry

Weld Purging tubes and pipes for the Oil and Gas Industry is crucial when joining metals such as stainless, duplex and chrome steels, as well as nickel alloys, titanium and zirconium. However, when welding larger pipe diameters it is not cost effective to completely fill tubes and pipes with expensive inert gas. Weld Purging Experts […]

Inflatable Weld Purging System for Welding Tubes and Pipes

Why use an Inflatable Weld Purging System? When welding metals, such as stainless, duplex, chrome steels, zirconium titanium and nickel alloys, it is vital that the oxygen surrounding the welding zone is replaced with an inert gas such as argon. When welds are made in the presence of oxygen, they are oxidised, which can lead […]

Weld Purge Monitor® for the Nuclear Industry

With the growth of Nuclear Power activities around the World, there is a large volume of stainless steel pipework that will need to be welded to a high standard, with no oxidation that can lead to loss of corrosion resistance. To meet the higher standards of welding that the Nuclear Industry expects, a unique Weld […]

Fire Sprinkler Systems – Easy Valve Replacement with Qwik-Freezer™

Replacing valves in fire sprinkler systems can be a challenge, especially when the pipelines have liquids running through them. One option is to completely drain the system to make the repairs, which can prove costly, time consuming and problematical as to where to drain the liquid. Pipe Freezing Experts Huntingdon Fusion Techniques HFT® recently introduced […]

Flexible Welding Enclosure® for use in the Aerospace Industry

When welding titanium or nickel alloy parts within the Aerospace Industry, it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm). Flexible Welding Enclosures® are available for a fraction of the cost of a rigid welding chamber, providing a technically viable option to […]

On-Site Weld Purge Monitor® with PurgeNet™

Welders often face difficulties when working under the conditions experienced on-site. When welding critical joints on-site the challenges might come from exposure to extremes of heat and cold, harmful sand and dust and even hazardous fumes. Therefore using an expensive Weld Purge Monitor® in such conditions may not always be ideal. To overcome these challenges, […]

Low Cost 1 PPM Weld Purge Monitor® designed for the Process Industries

Due to the constant upward trends in Quality Control procedures, there is growing pressure on the Process Industries to carry out their welding in the absence of oxygen to an ever increasingly lower level. Metals such as stainless steel, titanium, zirconium and nickel alloys are now available to these industries to ensure the greatest strengths, […]

Weld Trailing Shields ® for Bright, Shiny, Tube, Pipe and Flat Sheet Welds

Weld Trailing Shields for extended inert gas coverage when welding metals such as stainless steel, titanium, zirconium, nickel alloys etc, Weld Purging Specialists Huntingdon Fusion Techniques HFT® manufacture a range of Weld Trailing Shields®. The shield gas from torch cup leaves the metal usually before it has cooled below its oxidation point, discolouration because of […]

Leak Tight Pipe Plugging for the Oil & Gas Industry

There is a large variety of pipe plugging and blocking requirements in the Oil and Gas Industry, including repair work, leak testing, weld purging and debris stopping. One major concern is the entry of debris into pipes during operations. The Pipestoppers® Division of Huntingdon Fusion Techniques HFT® now design and manufacture a range of low […]

Weld Purge your Heat Treated Pipes Confidently with HotPurge®

High strength steel joints must pre-heated prior to welding and also require a post-weld heat treatment. Weld joints of this nature are often purged of oxygen and welded in an inert atmosphere to reduce the risk of ‘sugaring’, an imperfection that could allow metal pieces to break off inside pipework and cause damage to turbines, […]
