RT DOUBLE CARCASS 21 bar 7000 Series

Type 7852 F RT Tanker End (Jumbo) Hose

  • Single Carcass Hose FLEXOMARINE Tanker End for use to connect the ship’s manifold and the floating hose string
  • Identified by a double circumferencial white bands at the tanker end
  • In the hose fittings liftings lugs can be welded to attach pick up device
  • Each lug are tested to support Safe Working Loads as follow:
    • 12″ = 100 kN
    • 16″ = 150 kN
    • 20″ = 200 kN
  • Rated Working Pressure: 21bar
  • Minimum Bending Radius: 4D (up to 2D without any permanent deformation)
  • Minimum Reserve Buoyancy: 20% including the weight of NSV (North Sea Valve) up to 2,5 ton
  • Electrical Continuity: Discontinuous or as requested
  • Leak Detection: In case of failure of the primary carcass, a double leak detection system (DDEMAS – Double Detection Expansion and Mechanical Anti-Pollution System), confirms the failure of the primary carcass. It’s operation combines the natural expansion of the secondary carcass with a change in the hose profile and an increase on its buoyancy, futhermore a rod installed in each hose end that is inicially embedded will become visible after the burst of the primary carcass giving additional confirmation of the failure
