Abstract
A composite hose includes a tubular body of flexible material for transferring cryogenic fluid through the hose and for preventing fluid leakage through the body. The tubular body includes an inner wire helix spirally wound along the length of the hose, an outer wire helix spirally wound along the length of the hose, at least two reinforcing layers placed in between the inner and outer wire, at least one sealing layer placed between two reinforcing layers, an end fitting at both ends of the tubular body, each end fitting provided with a part for connection to another hose flange and an elongated cylindrical part, which is divided in an anchoring area for anchoring the tubular body and a static sealing area for fluid tight sealing of the hose. A gas tight sealing is created by bonding the at least one sealing layer to the cylindrical part over a ring shaped bonding area.
