Can the DONÂ® discharge hose for cement, dry bulk substances be used for pneumatic transfer of silica and sand at temperatures down to -40Â°C?

Yes. The DONÂ® discharge hose for cement, dry bulk substances is specified for pneumatic transfer of dry abrasive materials including silica and sand, and its operating temperature range is from â40Â°C to +70Â°C. It features an antistatic, abrasionâresistant NR/SBR inner layer (R < 10^6 Î©), synthetic cord reinforcement and an antistatic abrasionâ and ozoneâresistant outer layer, and is used for transfer from rail/road tankers and silos. For higher abrasion applications consider the XE variant (inner layer abrasion 50 mm^3 and copper wire).

Is the DONÂ® discharge hose for cement, dry bulk substances suitable for abrasive materials like silica and sand?

Yes. The DONÂ® discharge hose for cement, dry bulk substances is suitable for abrasive materials like silica and sand. Itâs specifically designed for pneumatic transport of dry abrasive materials (cement, sand, gravel, silica) with an abrasionâresistant NR/SBR inner layer (70Â±5 mmÂ³ per ISO 4649) and an abrasionâresistant outer layer; XE versions offer even higher abrasion resistance (50 mmÂ³) and include a copper wire for antistatic protection. Working pressure 5â6 bar and temperature range â40Â°C to +70Â°C.

Does the DONÂ® discharge hose for cement, dry bulk substances have antistatic properties (R < 10^6 Î©)?

Yes. The DONÂ® discharge hose for cement, dry bulk substances has antistatic properties (R < 10^6 Î©). both the inner and outer rubber layers are antistatic. Indices marked XE feature a high-abrasion antistatic inner layer and include a copper wire for grounding.

Soft suction hose, for larger diameters and small thicknesses almost flat at rest, intended for pneumatic transport of dry bulk materials. Inner layer made of black, smooth, antistatic rubber (R < 10⁶ Ω), abrasion-resistant (70±5 mm³ according to ISO 4649, formerly DIN 53516). Reinforcement with synthetic cord. Outer layer made of antistatic (R < 10⁶ Ω) abrasion-resistant rubber, weather-resistant and ozone-resistant. The hose is primarily used for the transfer of cement, sand, gravel, silica, and other dry abrasive materials from rail tankers, road tankers, and silos. Standard length: 60 m (or 120 m – contact Tubes International). Inner layer: black NR/SBR rubber. Reinforcement: synthetic cord. Outer layer: black NR/SBR rubber. Working pressure: from 5 bar to 6 bar – depending on the hose diameter. Operating temperature: from -40°C to +70°C. Indices marked at the end with the letters XE have an inner layer made of high-abrasion-resistant antistatic rubber (abrasion 50 mm³ according to ISO4649) and with a copper wire.
