<p>A hose for liquefied gas consists of an inner spiral of Cr-Ni-Mo steel wire, surrounded by a polyamide braiding and a polyamide hose. The following Al foil, embedded in two polyamide foils, ensures the gas-tightness. Another polyamide foil is surrounded by polyamide braiding, enclosed in polyamide hoses which have been blow-moulded to ensure tightness against the liq. ingress. Another tear-resistant layer is followed by a second metal spiral embedded in plastic braiding. The final outer protective sheath is a polypropylene tissue, coated with EVA copolymer. This hose cuts out icing and gas diffusion and reduces cold losses to a min.</p> |
