Abstract
The invention relates to a process for manufacturing a hose including a layer of ultra-high molecular weight polyethylene on at least the inside or the outside, which layer is directly bonded to an elastomeric layer, the layer of polyethylene being provided by folding an oblong polyethylene film to form an oblong tube with an overlapping seam in its longitudinal direction, resulting in a hose fit for uses, even at low temperatures, in which the inside and/or the outside of the hose are/is exposed to the action of chemical substances and/or of substances having a strongly abrasive action.
