Abstract
Cryogenic transfer hose for hydrocarbons comprising an inner hose, an outer hose arranged around the inner hose in a concentric manner and a spacer member bridging an annular gap between the inner and outer hoses, a fibrous insulation material forming a three dimensional matrix of fibers being comprised in the annular gap, characterized in that the outer hose comprises an elastomeric and/or a plastic material, the fibrous material being contiguous overall best a part of the length of the hoses with the inner and outer hose and forming a spacer member.
Claims26
A method of constructing a cryogenic transfer hose, comprising:
- providing a first and second hose segment each having an inner and outer hose, compressed fibrous or porous material between the inner and outer hoses and a connecting flange at an end part,
- interconnecting the connecting flanges of the first and second segments, and
- increasing the air pressure of the fibrous or porous material in the first and second segments after interconnection.
