Abstract
The utility model discloses a kind of tension composite flexible vertical pipe, the tensile layer of standpipe is wrapped in riser interiors structure by some elastic metallic rope closing twists to be formed, and the elastic metallic rope includes wire rope core and rope strand, and the rope strand is twisted spiral wound on wire rope core.The utility model improves standpipe tensile property, the tensile load that standpipe is born is become larger, extends service life.
Description
Technical field
It the utility model is related to marine riser, and in particular to a kind of tension composite flexible vertical pipe.
Background technology
Deep-sea flexible riser is to connect sea floating platform and the passage of subsea production equipment, is MULTILAYER COMPOSITE tubulose knot
Structure, is mainly made of polymeric layer and metal spiral layer, has many advantages, such as:Larger deformation can be born, is easy to
Installation, corrosion resistance is good, recyclable etc..These advantages make it in Marine oil and gas resource exploitation with commonplace.Due to
The presence of the factors such as dead weight, deep-sea flexible riser can bear larger tensile load, and tensile layer is the main load of tensile load
Layer, traditional standpipe tensile layer are made of a plurality of rectangular section steel band, easily occur in the case where tensile load is excessive moulding
Deformation is even broken.
Utility model content
Goal of the invention：The purpose of this utility model is to provide a kind of tension composite flexible vertical pipe, solves existing standpipe tension
Plastic deformation or fracture easily occur for layer.
Technical solution：Tension composite flexible vertical pipe of the present invention, its tensile layer are close by some elastic metallic ropes
It is spirally wound in the internal structure of standpipe and is formed.
The elastic metallic rope includes wire rope core and rope strand, and the rope strand is twisted spiral wound on wire rope core.
In order to ensure the rigidity of elastic metallic rope and toughness, make elastic metallic rope stable working, be not easy whole root fracture suddenly,
The elastic metallic rope is Elastic Steel cord, and the rope strand is the circular silk material that steel alloy is formed by cold drawn or cold rolling.
Rub to increase steel wire rope elasticity and toughness, lubrication steel wire, mitigation, improve service life, the wire rope core is fiber crops
Core.
Beneficial effect：The utility model improves standpipe tensile property, the tensile load that standpipe is born is become larger, standpipe
Tensile layer is unlikely to deform or is broken, and service life extends, also with light weight, anti-fatigue ability is strong, strong shock resistance, resistance
The features such as large deformation ability is strong.
Brief description of the drawings
Fig. 1 is the tensile layer structure diagram of the utility model；
Fig. 2 is to simplify spiral elasticity metallic cable schematic diagram；
Fig. 3 is elastic metallic rope concrete structure schematic diagram.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, tension composite flexible vertical pipe internal structure surface wrap has some elastic metallic ropes 3, preferably bullet
Property steel wire rope, Elastic Steel cord include wire rope core 1 and rope strand 2, and rope strand 2 is twisted spiral wound and forms elastic wire on wire rope core 1
Rope 3.Wire rope core 1 is hemp core, and hemp core plays increase steel wire rope elasticity and toughness, lubrication steel wire, mitigates friction, improves service life
Effect, rope strand 2 is the circular silk material that steel alloy is formed by cold drawn or cold rolling, has very high intensity and toughness, then pass through painting
Anti- seawater grease is with certain waterproof and anticorrosion ability, the two is combined, and the Elastic Steel cord intensity formed afterwards is high, conducts oneself with dignity
Gently, stable working, to be not easy whole root fracture, reliability suddenly high.The tensile strength of steel wire rope is higher than the steel knot of same cross-sectional area
Structure, using Elastic Steel cord as unit it is spiral into the more tensile capacity of standpipe tensile layer it is superior.
