Sand Gravel and Mining Hose

Highly abrasion resistant hoses used in sand and gravel pits, dredging, mining, coal and grain handling.



A402 and A412: Sand, gravel and mining hose.

Sizes: 50mm to 915mm inside diameter

Lengths: Up to and including 300mm = 19.5 mtr - 356mm and above = 12 mtr.

Applications: Highly abrasion resistant hoses used in sand and gravel pits, dredging, mining, coal, grain handling and many more industries where abrasive products are transported.

Lining: Two types of lining are available in thicknesses from 3mm to 12mm depending on the nature and severity of the application. A tan coloured gumstock 40# hard Natural rubber for fine air-borne abrasives [A402] and a black reinforced 60# hard Natural rubber for slurries and heavy abrasives such as gravel and rock [A412].

Reinforcement: Multiple layers of synthetic cord and a single steel helix, giving minimum 3.5:1 safety factor and a minimum bend radius of up to 6x bore size.

Pressure: Rated up to 10 bars working pressure. Higher working pressures are available on request. Hose assemblies are tested upon request.

Cover: Corrugated for greater flexibility. Tough weather and abrasion resistant. Two types are available, black Natural rubber for normal use or black Neoprene rubber for more extreme external conditions.
Smooth outer covers are available to accommodate external aluminium flanges.

Couplings: The following types are usually supplied where the abrasive material would excessively wear a steel hose tail: Integral flanges with steel backing plates. D section ring with two-piece split flanges and Beaded End with one-piece captive flanges.

However, a heavy duty thick walled carbon steel hose tail, wired, strapped or Built-in can be an option.

Variations: Lining thickness' can vary depending on the nature of the application. Thicknesses are available in increments of 1.5mm commencing at 3mm. e.g. A402-3 = 40 deg hard gum stock, 3mm thick lining. A412-10.5 = 60 deg hard black, 10.5mm thick lining. If a neoprene cover is required for more extreme exposure conditions the letters 'CR' are added. e.g. A412-6-CR = 60 deg hard black, 6mm thick lining.
