Main Lining / Inner Tube: Smooth, oil and fuel resistant Pure Seamless and Extruded Acrylontrile Butadiene Rubber (NBR);
Safety Lining: special construction to prevent defects or damage cause by incidental tearing or superficial damages of the main lining;
Reinforcements: Multiple Plies of High Tensile Textile cord. One embedded helical Body Steel wire.
Single Carcass And Double Carcass
Outer Cover:Smooth black, Synthetic Rubber Resistant to Abrasion, Oil, Sea Water and Sunlight.
Fittings:End connections built in during manufacture. ASME B 16.5 Class 150lb or 300lb Weld Neck Flat Face or Raised Face on request.

Standards and Specifications
Zebung single carcass hoses are designed and produced in full accordance to OCIMF standards. These products are also subjected to manufacturing and testing requirements dictated by ISO 9000:2001 quality standards.
Rated working pressure
The oil hoses have a RWP of at least 15 bar. 19 bar and 21 bar hoses are also available if specified by the customer. They are suitable for operation at an internal pressure from minus 0.85 bar to the RWP.
Flow Velocity
The linings of Zebung submarine hoses are constructed from elastomers and fabrics suitable for continuous operation at a flow velocity of 21m/s.

The submarine hoses are suitable for use with crude oil and liquid petroleum products from -20℃ to 82℃, and an aromatic hydrocarbon content no greater than 50% by volume.
Electrical Continuity
A low resistance connection will be provide with a copper wire and helix steel wire.

1. connecting tanker and discharge facilities
2. rated working pressure: 21 bar
3. electrical continuity: electrical continuous or discontinuous
4. leak detection system: after the failure of the primary carcass, the detector will react to the leakage to remind the operator to remove the damaged hose to avoid economic loss and environmental pollution.

Specifications can be designed by customer requirements.
