Very strong, thick, flexible hose intended for extraction and conveying abrasive bulk materials: granulates, grain, sand, gravel. thick wall and very dense spiral reinforcing ensures high resistance to pressure and vacuum. very smooth inside, non-compressible, not very pliable (r=4xD), retains its flexibility also in low temperatures. hose o sound resistance to abrasion, resistant also on oils and gasoline. Assembly on connectors with bridge clamps (prawo-handed) or assembly special on ends industrial e.g. flange. Other diameters may be available on special order. versions: P3 S PU – version standard, with polyester – polyurethane, very resistant to abrasion and P3 S PU AE – version with polyether – polyurethane, o sound resistance to abrasion, resistant to microbes and hydrolysis; with approval for contact with substances food, compliant with requirements European 1935/2004/EC and 10/2011/EU (simulant E), 2023/2006/EC (GMP) and American FDA 21 CFR 177.2600 and 178.2010. is suitable for time contact with food at conveying dry, bulk, free of fat on surface, substances food – on conditions defined in declaration conformity the manufacturer (Available in Tubes International); P3 S PU AS – version antistatic (R ≤10 8 Ω), compliant with TRBS 2153 and for extraction also with TRGS 727, with polyether – polyurethane, o sound resistance to abrasion, resistant to microbes and hydrolysis. Hose material: transparent polyester-polyurethane (P3 S PU), transparent polyether-polyurethane (P3 S PU AE and P3 S PU AS). Wall thickness measured between the spiral: 2 mm. Reinforcement: dense spiral with wire steel. Operating temperature: od -40°C up to +100°C.
