MANGUEIRA DE TRANSFERÊNCIA CRIOGÊNICA PARA HIDROCARBONETOS MATERIAL ESPAÇADOR ISOLANTE FIBROSO, E, MÉTODO PARA CONSTRUIR UMA MANGUEIRA DE TRANSFERÊNCIA

摘要

This invention relates to a 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 fibres being comprised in the annular gap, characterised 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.
