Advanced Weld Purging with the PurgEye® 200

Metallurgically sound and oxide-free welds are a minimum requirement now when welding stainless steel, zirconium, nickel alloys and titanium. Quality control procedures are in place within most industries and welders are no longer able to ‘guess’ when their oxygen level is low enough to begin welding. Oxygen levels as low as 50 parts per million […]

Save Money by Restricting your Weld Purge Zone

It is often very common for welders to spend hours waiting for their weld purge level to be low enough to begin welding. Without restricting the purge zone with an inflatable pipe purging system when welding stainless steel, titanium or zirconium tube and pipes, displacing the oxygen in entire pipelines with an inert gas (usually […]

Highly Accurate 100 ppm Weld Purge Monitor for Welding Stainless Steel

Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy only at ambient conditions. The low cost, hand […]

Inflatable Welding Enclosures provide low cost Argon Gas Shielding Environment

Welding applications within industries such as the Aerospace, Additive Manufacturing and F1 Racing as well as Medical, Pharmaceutical, Semiconductors and any other company that needs super clean welding joints, have a requirement of absolute cleanliness and smoothness of surfaces, ensuring each weld is mechanically stable and free from oxidation. Titanium is often the metal of […]

Low Cost Weld Purge Barrier for a wide range of Pipe Sizes

Weld Purging various sizes of tubes and pipes at a low cost can be challenging. Many welders today continue to construct their own dams to cut costs. Homemade dams made from material such as foam, sponge or paper can often lead to loss of welds when they leak or slip from position thus flooding the […]

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 […]

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 […]

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 […]

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 […]

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 […]
