Cost Effective Pipe Repairs with Accu-Freeze™

When making repairs to pipes, for example changing valves, it is common to have to drain down the entire system before the repairs can be made, which can lead to high disposal costs, loss of product and cost of time spent draining and disposing of the product. To dramatically reduce these costs Accu-Freeze™ is available […]

Huntingdon Fusion Techniques HFT®’s Technical Articles

Huntingdon Fusion Techniques share their Technical Knowledge. Since the 1970’s our Technical Experts have used their scientific knowledge to research and develop our Weld Purging Technology, which we continue to do with the help of our customers. Huntingdon Fusion Techniques work closely with Dr Michael Fletcher of Delta Consultants. Dr Fletcher is a qualified Welding […]

Heavy-Duty Pipe Plugs

Pipe stopping and blocking where there are chemicals or high temperatures present can cause many challenges in a variety of industries including Plumbing, Oil and Gas and Petrochemical. Furthermore, if those pipes have some small ovality problems it presents additional difficulties in order to achieve a good sealing. Peripheral Sealing Plugs for heavy-duty applications such […]

Argweld Weld Trailing Shields

Argweld Weld Trailing Shields are an important addition during the welding of stainless steel and titanium tubes, pipes and sheet metalwork, to ensure that the weld environment is totally free from oxygen.A Argweld Weld Trailing Shields ® provide an additional inert gas coverage to that of the welding torch, during and after welding, which forms […]

Eliminate Thoria by Switching to MultiStrike® for Safer Welding

Thoriated Tungsten Electrodes contain thoria, a radioactive element that can be dangerous to heath. During the grinding of the electrode there is a generation of radiotoxic dust, with the risk of this being inhaled by the welder. Welders today continue to use thoriated Tungsten Electrodes. Because thoria was much cheaper than alternative elements to lower […]

Titanium Welding with the PurgEye® Desk

The Welding Institute (TWI) state 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. In the form of a powder or metal shavings titanium […]

Chemical Resistant Inflatable Stoppers for blocking pipes containing hydrocarbon liquids and gases

During petrochemical operations, where hydrocarbons are present in liquid or gas form, inflatable stoppers are often used for various applications such as debris stopping, leak testing, low-pressure hydrostatic tests, blocking the release of hydrocarbon gases and a variety of plumbing operations. To meet the challenges of such intense conditions, the Pipestoppers® Division of Huntingdon Fusion […]

HFT visit Hinkley Point, the largest construction site in Europe

Through the Wales Nuclear Forum, we were recently invited on a tour of Hinkley Point C, the largest construction site in Europe, a project to construct a 3,200 MWe nuclear power station with two EPR reactors in Somerset, UK. The landscape of Hinkley Point is dominated by two nuclear power stations: Hinkley Point A, with two Magnox […]

Inert Shielding Gas Monitor for Stainless Steel Welding

Inert shielding gas is used to protect high integrity welds from oxygen and water vapour during TIG (GTAW) and Plasma (PAW) welding processes. When welding tanks, vessels, chambers and pipes, the most cost effective inert gas used for shielding is argon. As argon is heavier than air, it displaces the air containing oxygen and water […]

Inert Gas Welding

Inert gas welding requires the oxygen level within the weld zone to be purged to a level as low as 100 ppm or less. During inert gas welding the oxygen level should be monitored before, during and after the process to assure that the level will fall slowly to at least 100 ppm without rising […]

Standard and Custom Made, Low Cost Weld Purge Dams

When welding stainless steel, titanium or zirconium pipes, or pipework, the oxygen level within the pipe must be reduced to a level of 50 ppm, or lower in certain cases. The most cost-effective solution is to restrict the volume around the joint with a Tandem Weld Purging System. For the purging of short pipe pieces […]

Ensure your Pipe Purging System doesn't burst with PurgeGate®

Various Inflatable Pipe Purging Systems are in use Worldwide for welding titanium, stainless steel and zirconium tubes and pipes. Often, these purging systems are inflated beyond their capacity and burst mid-weld, resulting in a lost weld and broken purging system. To ensure the gas going through the pipe purging system is controlled, Huntingdon Fusion Techniques […]
