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.

Application
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.

Characteristic
1. connecting sea chest and buoy on buoy system
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.
