Abstract
The present invention concerns a high-pressure hose comprising a liquid and gas tight inner liner made from rubber, plastic or thermoplastic elastomer, at least four helically laid reinforcing plies embedded in polymer material, and an outer cover layer made from rubber, plastic or thermoplastic elastomer, wherein adjacent reinforcing cable plies are directed in the same direction and the follow-up ply pair is laid in opposite sense. Additionally, the pitch of filaments of adjacent unidirectional reinforcement plies is the same and the number of filaments is equal or different. The present invention further concerns methods for the production of such hoses and the use of such hoses.
