GAS HOSE — Industrial & Food Hose

The conductive wire and the cover compound. An air hose is rated on pressure alone, while this one carries a copper wire through the wall for static and a flame-retardant NBR + CR cover, at 10 bar over ten codes from 19 to 203 mm.

Only where the medium and the rating both fit. This hose is published for gas at 10 bar with 30 bar burst, and an NBR tube; a fuel line at higher pressure or with a different permeation requirement is a different build, and the two should not be swapped on the strength of the bore alone.

10 bar working with 30 bar minimum burst, on a 51 mm bore, a 64 mm outside diameter, a 300 mm bend radius and 1.98 kg per metre, on a 61 m coil.

A 203 mm bore with a 224 mm outside diameter, 12.71 kg per metre, a 1100 mm minimum bend radius, and a 30.5 m coil rather than the 61 m used at the small end.

Yes at 10 bar, which is the working rating on all ten codes. The NBR tube is built for gas and oil, and the 19 mm code at 0.69 kg/m is the size a cylinder-filling line usually runs.

Yes — both are inside the published duty of 10 bar with 30 bar burst. The 102 mm code at 4.59 kg/m and a 550 mm arc is a typical vapour-return size off a tanker, and the 152 mm code at 8.58 kg/m takes the larger yard runs.

Because a compound can only leak charge across its surface, and that path disappears as the cover wears. The conductive copper wire in the reinforcement is a continuous path along the hose, which is why the anti-static property is published as part of the build: a 19 mm code at 0.69 kg/m and a 203 mm code at 12.71 kg/m both carry it.

Heat and gas permeation attack the tube where the insert ends, and a clamp that crushes the copper wire breaks the static path at the same time. Keep the run away from a hot manifold, and check continuity end to end after any reassembly on the 203 mm code at 12.71 kg/m as much as on the 19 mm.

One coil, or cut lengths from a metre. The eight codes to 102 mm ship on 61 m and the 152 and 203 mm on 30.5 m, so a mixed order is packed by coil length and marked per length.

Per metre by bore, with the top end driven by mass: 0.69 kg/m at 19 mm against 12.71 kg/m at 203 mm. Send bore, total length, end fittings and destination for a firm figure.
