It is important when transporting inert gas supply to the welding zone that the hose is of high quality, ensuring the gas arrives without contamination.
Tailor made Inert Gas Feed Hoses are available from Huntingdon Fusion Techniques HFT® with leak tight fittings. Luke Keane, Technical Sales Manager for HFT® said: “Our range of gas hoses are available for transporting gas at both high and low pressure. Using a high quality gas welding hose will ensure a leak tight method of feeding non-contaminated gas into the welding zone for weld purging.
“All of our products are made to the highest quality and standard and are the best available for argon, helium and other gas use.”
The special low outgassing rate rubber feed hose comes complete with a regulator, which directly connects to any range of Inflatable Tube and Pipe Weld Purging Systems at one end and to the gas source at the other. Regulators can be changed or eliminated.
Conforming to British Standard BS EWN 599 Quality Standard, the Inert Gas Feed Hoses each have a temperature range from -30º up to 80ºC and a safety factor of three times working pressure 20 bar (300 psi).
A selection of leak tight adaptors is provided for attaching the inert gas regulator whilst the pre-fitted other end joins up with all HFT® Argweld® Pipe Weld Purging Systems. All of these high quality fittings will eliminate welding connection difficulties that welders might experience on site.
The Inert Gas Feed Hoses can also be supplied to all other TIG / GTAW welders as well as laser operators with their own special fittings as required. The hoses are available off the shelf in a standard range of lengths, 30 m, 25 m, 20 m, 15 m, 10 m and 5 m, with special made hoses made to order.
In the event of operators working in high temperature conditions as for heat-treated chrome steel pipework for example, special high temperature resistant hoses are available, complete with special heat resistant fittings.
HFT® advises welders and laser operators to only use top quality hose assemblies to feed inert gas for top quality welds!
