Inert Gas Feed Hoses for a Variety of Applications

Using a high-quality hose ensures noncontaminated gas is fed into the welding zone for weld purging. Huntingdon Fusion Techniques HFT (West Melbourne, FL) hoses ensure argon, helium, and other gases are available for transporting gas at high and low pressure.

The low-outgassing-rate rubber feed hose comes with a regulator that connects to tube and pipe weld-purging systems at one end and the gas source at the other. Regulators can be changed or eliminated.

Conforming to British Standard BS EWN 599 quality standard, the hoses have a temperature range from -30º C to 80º C 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 while the prefitted other end joins up with all HFT Argweld pipe weld purging systems. These high-quality fittings eliminate connection difficulties welders might experience on site.

The 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. Hoses can be made to order.

In the event of operators working in high temperatures, such as for heat-treated chrome steel pipework, temperature-resistant hoses are available with heat-resistant fittings.

Weld purging is the act of removing, from the vicinity of the joint, oxygen, water vapor, and any other gases or vapors that might harm the welding joint. Such gases may combine with the metal to form undesirable compounds that reduce corrosion resistance or contribute to cracks or other structural defects.
