Tube and Pipe Weld Purging Experts HFT COB established more than 40 years ago, are acknowledged as an international leader in the field of Weld Purging Products, Weld Purging, Weld Purge Monitoring (oxygen monitoring), Tube and Pipe Weld Purging Systems and all other areas of Purge Welding (Back Purging).
COB Industries, together with HFT guaranteed to help you achieve those sought after oxide free, zero colour welds time after time, combining our metallurgy experience, scientific knowledge and ever-advancing technical expertise.
HFT COB are proud to provide first class customer support, cost effective solutions, qualified technical advice and quality Weld Purging Products, Pipestoppers and Tungsten Electrodes for achieving ultra clean welds produced in a well purged environment.
The HFT COB Family Range of Weld Purge Monitors ® is designed to meet any requirement, measuring oxygen levels ranging from atmospheric content, down to as low as 1 parts per million (ppm), at which point no discolouration in welds should occur,
The PurgEye ® Weld Purge Monitors ® (Portable Weld Purge Trace PPM Oxygen Analyzers), including the World leading handy PurgEye ® 100, have been designed and manufactured with scientific knowledge, specifically for welding, as Oxygen Monitors, Oxygen Analyzers and Gas Analyzers are not accurate enough for weld purging. Achieving zero colour welds ensures the elimination of post-weld cleaning costs, which can be very high and in those cases making the cost of each weld ultra significant. With a Dew Point Sensor in the range, to be used in conjunction with the range of 10 ppm Weld Purge Monitors®, welders can now get an accurate dew point temperature reading throughout the welding cycle.
Equally, the HFT COB Family Range of Tube, Pipe and Pipeline Inflatable Weld Purging Systems and Weld Purge Dams (purge bladders) are considered absolutely vital to the welding industry for metals such as chrome steels, stainless steel, duplex steels, titanium, zirconium and nickel alloys, reducing time and money in backing gas costs, producing rapid purging times.
HFT COB can ensure all Weld Purging applications of tubes, pipes, flat sheet and plate are tailored for, whether using Water Soluble Weld Purge Film ®, Weld Trailing Shields ®, Weld Backing Tape ®, Weld Purge Plugs ™, Weld Purge Monitors ® etc.
Rigid Welding Chambers are a thing of the past with the introduction of the innovative Flexible Welding Enclosures ® for welding stainless steel, duplex steel, zirconium, nickel alloy and titanium parts, these replacement for TIG Welding Chambers are low cost, flexible, transportable and suitable for WAAM Additive Manufacturing. HFT COB’s Flexible Welding Enclosures ® are also in use within the racecar and titanium bike manufactures, replacing out of date Argon Welding Chambers.
All of our products are manufactured to internationally recognised standards following fully accredited quality control procedures. Leading fabricators across the globe rely on our products for the welding of stainless steel, titanium and other corrosion-resistant metals. Eliminating the requirement of Oxygen Monitors or Oxygen Analyzers, whether you’re in the construction, aerospace, oil and gas, petrochemical, dairy, food and beverage, racecar, titanium bike manufacturers or any other process industry.
Reducing the risk posed to health, HFT COB’s MultiStrike®, non radio-toxic Tungsten Electrodes have total traceability, with 10 times the number of arc strikes over thoriated tungsten electrodes under the same conditions, you get superior tungsten electrodes without the increased costs.
HFT COB’s Pipestoppers ® Division has a vast amount of expertise in the field of pipe plugging and stopping using mechanical, inflatable and freeze plugging techniques. Our customer base includes: plumbing, maritime, automotive radiator repair and weld purging. HFT COB have a remotely operated freeze system that is ideal for nuclear work with minimum exposure. We have a range of mechanical pipe plugs and inflatable stoppers to block exits, holes, ends, branches and more starting at 0.5" (12 mm) right up to large diameter stoppers for pipes up to 108" (3 m) diameter.
Recognised for our Purge Chambers, Pipe Purging, Weld Purging and Ice Plug Freezing expertise we have highly trained teams, with Weld Purging and Pipe Plugging training courses available, we are able to bring our technical knowhow to you.
We are able to provide all Tube and Pipe Purging Systems, Weld Purge Monitors ® and Weld Purging Accessories necessary for achieving those perfect clean, bright, oxide free welds using a dense ring purge of gas, fast back purge methods and rapid purge times.
