Medium wall thickness hose flexible of spiral reinforcing, intended for extraction and conveying bulk materials abrasive, granulates, chips, offcuts etc. used in various branches industry, in particular often used for discharge particles solid in industry plastics, wood, materials construction and metal. pliable and flexible, also in low temperatures. smooth inside, little compressible. dense and thick steel spiral coated white PVC ensures high parameters pressure, is resistant to corrosion and has good adhesion for material hose. hose o sound resistance to abrasion, resistant also on oils and gasoline. Assembly on connectors with bridge clamps (prawo-handed). Other diameters may be available on special order. versions: P3 PU – version standard, with polyester – polyurethane, very resistant to abrasion; P3 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; P3 PU EL – version conductive electrically (R ≤10 4 Ω), compliant with ATEX 2014/34/EU, TRBS 2153 and for extraction also with TRGS 727, can be used in zones hazard explosion po carrying out analysis risk, made with black polyether – polyurethane, o sound resistance to abrasion, resistant to microbes and hydrolysis. Hose material: transparent polyester-polyurethane (P3 PU), transparent polyether-polyurethane (P3 PU AS), black polyether-polyurethane (P3 PU EL). Wall thickness measured between the spiral: 0.8 ÷ 1.5 mm (depending on the diameter hose). Reinforcement: spiral with wire steel coated white PVC. Operating temperature: od -40°C up to +100°C.
