Welding Enclosures offer great savings

Welding Enclosures are frequently used when welding exotic metal parts made of materials such as titanium and nickel alloys where the atmosphere around the part needs to be completely free of oxygen, down to as low as 50 ppm or below. Welding Enclosures are often very expensive, they are made of metal chambers that are […]

Low Cost, Entry Level 10 ppm Weld Purge Monitor

Metals such as stainless steel, titanium, zirconium and nickel alloys are often required to be welded in an environment containing 100 parts per million (ppm) of oxygen or even less in some industries, guaranteeing the greatest weld joint strengths and the highest resistance to corrosion. To ensure oxygen levels are low enough before, during and […]

Pipe Freezing Made Easy

Pipe Freezing: Where repairs or modifications need to be made to valves or pipes containing liquids, it often seems that the only option is to drain the entire system causing high costs in loss of product, lost time in draining and refilling after repairs, possible disposal costs and loss of production. One answer to this […]

Safe, Fast and Low Cost Pipe Freezing with Qwik-Freezer™

Repairs or modifications on pipes with liquid contents can pose a financial challenge, especially when those fluids might otherwise have to be disposed of causing unnecessary costs and perhaps commercial difficulties. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides a cost saving solution to this problem with Qwik-Freezer™, the industry standard portable CO2 Pipe […]

Glass Fibre Backing Tape gives improved Weld Root Profiles

Weld Backing Tape® is a common material used where manual welding cannot control the weld root profile sufficiently, or when an automatic weld process is unable to reach satisfactory speeds while still obtaining satisfactory underbeads. Ceramic Fibre is in use within the Welding Community, which has a melting point of 1,800ºC, causing concern when temperatures during […]

Special High Quality, Leak Tight Welding Hose for Argon Feed

Advancing forward in weld purging technology, Huntingdon Fusion Techniques HFT® now manufacture tailor made Argon Gas Feed Hose assemblies with leak tight fittings. Luke Keane, Distributor Support for HFT® said: “It is important when welding stainless steels, titanium, zirconium and other reactive metals, that the welding zone is purged of oxygen, even down to as […]

Tight sealing Low Profile Pipestoppers for limited spaces and restricted access

Pipe blocking, plugging and sealing for duties such as repair work, leak testing, weld purging and debris stopping is easy with Pipestoppers®. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® design and manufacture a Range of Mechanical and Inflatable Pipestoppers® and Plugs to suit a variety of applications. The Low Profile Stopper is available for […]

The virtually non-destructible PurgEye® Site Weld Purge Monitor® for on-site conditions

Welders often face difficulties when working under the conditions experienced on-site. When welding critical joints in such situations, the challenges might come from working at height, 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 […]

Huntingdon Fusion Techniques HFT® to Exhibit at World Nuclear

Weld Purging Experts Huntingdon Fusion Techniques HFT® will be participating at the World Nuclear Exhibition in Paris from 26 – 28 June on the Welsh Government Pavilion, Stand No: 7-D9. Georgia Gascoyne, CEO for HFT® said: “Our Weld Purging Technology is designed to achieve oxide free, zero colour welds to nuclear standards. On display at […]

Lightweight Aluminium Plugs for Heavy-Duty Applications

There are many applications where pipes carrying chemical fluids (alkaline or acidic) or that are exposed to high temperatures need to be plugged or sealed. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® manufacture a Range of heavy-duty Aluminium Plugs to allow for arduous duties such as exposure to high temperatures and immersion in chemicals, […]

Heat Tint Charts

The following Stainless Steel and Titanium Heat Tint Charts are good reference guides for acceptable/non acceptable weld oxidation. A low level of oxygen before, during and after welding is necessary, in order to achieve a minimum oxidation and discolouration. These free Heat Tint Charts demonstrate what the standard authorities set (Norsok and The AWS) and what our […]

Cut Costs, Not Corners with QuickPurge®

Welders are always looking for time and cost savings when pipes need to be purged of oxygen before, during and after welding (weld purged). Weld purging large diameter pipework fabrications and pipelines not only carries a large price tag when it comes to time, it can also cost a lot in inert gas. Weld purging […]
