Continuing their pursuit to advance in Weld Purging Technology, Huntingdon Fusion Techniques (HFT®), now manufactures tailor made Inert Gas Feed Hose assemblies with leak tight fittings and a low outgassing rate.
Luke Keane, Technical Sales Manager for HFT® said: “It is important when welding all reactive metals that the welding zone is purged of oxygen, even down to as low as 20 parts per million (ppm). Our Inert Gas Feed Hose assemblies are the best way of transporting argon, helium and other inert gasses to the welding zone where a guaranteed leak tight, non-contaminated delivery is required.”
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.
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 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.
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).
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.
