Fluid-Tight end fitting for a Composite Hose and Method of Assembling a Composite Hose on Such end Fitting

A composite hose comprising a tubular body of flexible material for transfer of cryogenic fluid through the hose and to prevent fluid leakage through the body,

• the tubular body comprising;
• 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 and an elongated cylindrical part, the cylindrical part divided in an anchoring area for anchoring the tubular body and a static sealing area for fluid tight sealing of the hose, wherein on top of the at least one sealing layer a wire pack is placed for applying a radial compression force perpendicular to the tubular body axis onto the at least one sealing layer.

Method of making a composite hose consisting of the steps of:

• applying an inner helical wire on a cylindrical part of a hose end fitting,
• applying wrapped inner reinforcement layers,
• applying at least one sealing layers so that it is in direct contact with the cylindrical part of the hose end fitting
• bonding the at least one sealing layer to the cylindrical part over a continuous ring shaped bonding area.
• applying a wire pack for radial compression of the sealing layer in the bonded area
• applying wrapped outer reinforcement layers
• applying an outer helical wire of the hose covering the bonded area as well
