Flexible hose intended for conveying liquid substances food, water potable, chemicals. Layer inner hose made is with polyethylene high density (HDPE) o quality food. Material ten meets high requirements for water potable both in the scope the absence migration components for standing in hose water as and the absence tendency for formation biofilm (test microbiological). simultaneously Meets the requirements of for contact with food for liquid substances food and has very high resistance chemical (acids, bases, carbon, solvents). therefore hose It can be used for: 1) installations water potable (Germany: KTW, DVGW); 2) liquid substances food (water, juices fruit, alcohols, milk and its dairy products, fats and oils); 3) chemicals in wide the scope (selection in contact with Tubes International Sp. with o.o.). thanks to multilayer the structure hose, where layer intermediate and outer made are with soft polyethylene, hose is very flexible. Do mounting should use fittings with spigot (“tail” for hose) not having sharp barbs, which could po clamping cut layer inner with HDPE. standards and requirements : 1) industry food, contact with food – compliant with the European requirements 1935/2004/EC and 10/2011/EU (simulant fluids A, B, C, D1, D2), 2023/2006/EC (GMP). 2) approval for water potable KTW-A (certificate German institute hygiene) and DVGW W270 (microbiological test material). Inner layer: polyethylene HDPE. layer intermediate: natural soft polyethylene PE. Reinforcement: a polyester braid. Outer layer: blue soft polyethylene PE. Working pressure: 16 bar, dependent od temperatures. Operating temperature: from -15°C to +60°C.
