LIGHT-WEIGHT COAXIAL TYPE STEAM RECOVERY HOSE

摘要

There is disclosed a coaxial vapor recovery hose assembly (10) comprising an inner hose (26), an outer hose (12), and means for holding said hoses in concentric relationship (44); wherein said inner hose (26) is substantially reinforced to be relatively incompressible as well as being capable of bearing tensile stress applied to the assembly and having an outside diameter; wherein said outer hose (12) is corrugated and has an inside diameter larger than said outside diameter to define a vapor passageway (30) therebetween.
