Compact flange at the end of a hose, fully embedded in rubber, using a continuous inner liner and integrated gasket.
This creates a perfect seal between conveyed product and hose structure, resulting in a hose that survives harsher conditions for longer.
Most common type of flange, using a stiff metal connector at the end of a hose, Binding steel wires fix the nipple flange to the hose body structures.
Alternative flange: Nippleless.
Hose built with two independent carcasses made of steel cable layers which function independently.
The first working carcass provides internal pressure resistance, while the reinforcement carcass provides resistance to bending and tensile loads and stresses as well as protection of the main carcass from the external environment.
Hose built with carcass made of a textile layer and steel helix reinforcement, forming a single carcass.
The Double carcass consists to an additional carcass above the first, and a leak detection system (LDS) in the event of failure in the first carcass. The second carcass contains oil in the event of a failure in the first.
Integrated Bend Stiffener
Integrated Bend Stiffener
IBS stands for Integrated Bending Stiffener : IBS is a built in bending stiffener fitted at the end of a hose at the manifold - the hardware to which the hose connects, or at all connections between hoses. The bending stiffener protects the end of the hose from bending too much, and provides a smooth transition of bending stiffness by gradually increasing the outer diameter from the central area to the flange.
FKM refers to the 'fluoroelastomer' category according to ASTM (American Society of Testing and Materials) when classifying materials. This type of rubber is resistant to heat and resists chemcial reactions. Hence, it is particularly suitable as the inner liner of a marine hose when handling corrosive fluids like high purity acids. They also presents a very low gas permeability and excellent resistance to oils.
Orange PolyUrethane “PU”
Orange PolyUrethane “PU” is an extra anti-abrasion outer cover for the floating and submarine hoses which reducing repairing due to wear and cuts in operation.
New solution for ship-to-ship
Trelleborg is launching a new solution for ship-to-ship (STS) transfer, in the form of KLELINE STS, bringing new thinking to the field of STS oil transfer. We take a look at how it works and why it makes sense to challenge conventional wisdom on STS transfer.
Seawater intake (SWI) diverless and diver assisted configuration
The interface between a seawater intake riser and the hull of a vessel can be tied up and bolted to a flange, or laid down from a caisson to a dedicated receptacle without the need of divers
For diver-assisted configuration the interface is made by a spool piece
For diverless configuration, the interface is made by a riser head and a riser seat integrated directly to the hull during construction
Strainer (n): A filtration device fitted at the inlet of a seawater intake riser to prevent fish and marine fauna from being sucked in.
Boil-off gas (BOG)
LNG tankers are designed to carry natural gas in liquid form at a temperature of – 163°C, close to the vaporization temperature. Despite tank insulation designed to limit the admission of external heat, even a small amount of it will cause slight evaporation of the cargo. This natural evaporation, known as boil-off is unavoidable and has to be removed from the tanks in order to maintain the cargo tank pressure.
