Best answer

Rubber hose:

  • Internal wire helix - The reinforcement steel wire used to support the internal lining or tube of rough bore rubber hose, distinguishing it from the smooth bore type.
  • Rough bore rubber hose - A rubber hose with an internal wire helix.
  • Smooth bore rubber hose - A rubber hose without an internal wire helix.
  • Softwall rubber hose - A rubber hose that lacks any helix wire and which has a light-wall construction with a vacuum capacity less than 25 in. Hg (−85 kPa).  Soft-wall hose should not be used in ship-to-ship lightering.  However, soft-wall hoses may be used for floating hoses for shore to ship transfers in protected harbors and waterways.

Composite hose:

  • Composite hose - A synthetic film and fabric carcass built up on a helix of wire, wrapped in a protective cover and secured by an outer helix of wire.  Composite hoses are not suitable for use in the transfer of light or heavy crude (maximum fluid viscosity shall be less than 400 cSt [400 mm2/s]) or in ship-to-ship lightering service.
  • Inner or outer wire helix - The reinforcement steel wires used to secure the synthetic film and fabric carcass of composite hose.
