Abstract
The utility model belongs to defeated systems technology field outside FPSO, disclose a kind of novel outer defeated inside hose support construction, the casing play of outer defeated hose is improved to multiple independent round steel loops by whole steel wire continuous winding to be spaced substantially equidistant, by the bending property for adjusting the adjustable outer defeated hose of steel loop spacing, this structure will not cause metal fatigue to extend phenomenon in defeated hose use process because of being stretched with bending stress outside, each steel loop independently supports outer defeated hose construction, it does not influence from each other, will not be broken because of some position of some steel loop causes outer defeated hose construction to destroy;Simultaneously, outer defeated hose at sea is influenced that the stress of bending and stretching can be produced by stormy waves stream in flotation process, between the casing play steel loop of this structure independently of one another, it will not mutual extrusion, outer defeated hose bending performance and endurance life can be improved, extend outer defeated hose service life, ensures the safety of crude oil exporting.
Description
Technical field
The utility model belongs to defeated systems technology field outside FPSO, in particular to defeated system outside a kind of FPSO
Outer defeated inside hose support construction.
Background technique
Outer defeated hose is the key that the outer defeated long line equipment of system on FPSO, is the unique passage of FPSO crude oil exporting.It is common
Outer defeated hose mainly have following type: 1, first pipe;2, No. two pipes;3 supervisors;4, reducer pipe;5, tail pipe;6, side of a ship pipe.This
The hose of several types is different with undertaking for task in structure design aspect different from according to itself present position.But it is main
The design aspect gap of structure is little, all have flange spool, inner glue layer, cord reinforcing layer, casing play, mesoglea, interlevel layer,
Outer glue-line etc..Outer defeated hose is frequently necessary to bending, stretching, extruding etc. in use.Wherein casing play is as outer defeated hose
Internal main support structure undertakes the functions such as tension, resistance to compression, bending.The casing play of outer defeated hose uses a continuous winding at present
Fixation with steel wire spring structure is similar on enhancement layer, as shown in Figure 1, to be easy to appear metal fatigue later existing for long-time use
As causing too long eventually lead to of hose elongation to be scrapped.
Utility model content
Based on outer defeated hose service life is extended, the goal of the invention of crude oil exporting safety is ensured, the utility model provides one
The novel outer defeated inside hose support construction of kind, is improved to multiple independent circles for whole steel wire continuous winding in the prior art
Steel loop is spaced substantially equidistant, this structure will not lead to gold with bending stress because of being stretched in defeated hose use process outside
Belong to fatigue elongation phenomenon, while the bending property and endurance life of outer defeated hose can be improved, so that extending outer defeated hose makes
With the service life, the safety of crude oil exporting is ensured.
In order to solve the above-mentioned technical problem, the utility model is achieved by technical solution below:
A kind of novel outer defeated inside hose support construction, including the casing play between inner glue layer and enhancement layer, the skeleton
Layer is spaced substantially equidistant by multiple round steel loops and is formed.
Wherein, the steel loop is not less than BS3592 using steel grade, and tensile strength is not less than 650N/mm2, diameter of section
Not less than 20mm.
The beneficial effects of the utility model are:
The utility model can prevent tube body from collapsing as outer defeated hose body skeleton, while can resist certain external force
Extruding avoids tube body from deforming, and so that outer defeated hose had not only been had certain rigidity but also has flexibility, mainly by the casing play of outer defeated hose
Multiple independent round steel loops are improved to by whole steel wire continuous winding to be spaced substantially equidistant, it can be with by adjusting steel loop spacing
Adjust the bending property of outer defeated hose, this structure will not be led because of being stretched with bending stress in defeated hose use process outside
Metal fatigue is caused to extend phenomenon, each steel loop independently supports outer defeated hose construction, do not influence from each other, will not be because of some
The fracture of some position of steel loop causes outer defeated hose construction to destroy;Meanwhile outer defeated hose is at sea in flotation process by stormy waves stream
Influence can produce the stress of bending and stretching, between the casing play steel loop of this structure independently of one another, will not mutual extrusion, can be with
Improve outer defeated hose bending performance and endurance life, extends outer defeated hose service life, ensure the safety of crude oil exporting.
Detailed description of the invention
Fig. 1 is the overall plan view of the casing play of the defeated hose in prior art China and foreign countries;
Fig. 2 is that the utility model provides the schematic diagram of internal structure of outer defeated hose;
Fig. 3 is the partial schematic diagram for the casing play that the utility model provides outer defeated hose.
In figure: 1: enhancement layer;2: casing play;3: mesoglea;4: steel loop.
Specific embodiment
For the content, feature and effect that can further appreciate that the utility model, the following examples are hereby given, and cooperates attached drawing
Detailed description are as follows:
As shown in Figures 2 and 3, a kind of novel outer defeated inside hose support construction is present embodiments provided, mainly by interior glue
The structure compositions such as layer, enhancement layer 1, casing play 2, mesoglea 3, interlevel layer and outer glue-line, whole outer defeated hose is by flange end and bone
Rack-layer 2 supports the tube body of entire outer defeated hose.The casing play 2 of the utility model is spaced substantially equidistant by round steel loop 4.
In the case where guaranteeing the original other structures of outer defeated hose and the constant situation of material, selection is not less than using steel grade
BS3592, tensile strength are not less than 650N/mm2, seamless round steel loop 4 of the diameter of section not less than 20mm manufacture outer defeated hose bone
Rack-layer 2 substituted a whole continuous winding steel wire of original outer defeated hose casing play.
Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not
It is confined to above-mentioned specific embodiment, the above mentioned embodiment is only schematical, is not restrictive, ability
The those of ordinary skill in domain is not departing from invention objective and scope of the claimed protection feelings under the enlightenment of the utility model
Under condition, the specific transformation of many forms can also be made, these are belonged within the protection scope of the utility model.
Claims (2)
