Description
Technical field
The present invention relates to a kind of preparation facilities of casing play of ocean flexible pipe and processing method, particularly a kind of ocean flexible pipe
S type casing plays preparation facilities and processing method.
Background technology
With continually developing for deep-sea oil gas resource, obtained as the compliant riser of Upper float and subsea wellheads interface channel
To being increasingly widely applied.Compared to the standpipe of other forms, compliant riser is while larger axial rigidity is kept, also
The radial pressure that seawater and oil gas are brought can be born.Deep-sea non-adhesive flexible hose contains one layer of casing play, and it is by resistance to
Corrosion metal interlocks steel band and is entwined by the helical with nearly 88.5 ° of body axis, and major section is shaped as S types.Spiral shell
Rotation winding and interlocking space structure type can ensure that structure has enough bending properties.The major function of casing play is for pipeline
External pressure load is resisted, provides enough radial rigidities to support internal lining pipe for pipeline, prevents that non-adherent caused by external pressure load is soft
Property pipeline conquassation failure.
Because casing play is manufactured using the stainless steel of better performances, material stiffness is big, is difficult machine-shaping, and bone
It by cross sectional shape is that the interlocking of S steel band of model is entwined that rack-layer, which is, at present at home also without preferable preparation facilities and correspondingly
Processing method.Therefore, the preparation facilities and processing method of exploitation ocean flexible pipe S type casing plays, to adapt to Chinese deep-sea oil gas
The development of development of resources cause, is the work of a significant.The content of the invention
It is an object of the invention to provide a kind of preparation facilities of the S type casing plays of ocean flexible pipe and processing method, sea is overcome
The defect of foreign flexible pipe S types casing play processing difficulties, the S type skeleton helical layers processed using apparatus and method of the present invention are taken
Button is stable, is not in that hasp frees phenomenon, and mould structure is simple, and processing mode is simple and efficient, greatly improves sea
The processing efficiency of foreign flexible pipe S type casing plays, reduces production cost.
To achieve the above object, the technical scheme is that：
A kind of preparation facilities of the S type casing plays of ocean flexible pipe, it is characterised in that：It includes roller press and roll die, described
The paired roll die that roller press is gradually changed by five groups of structures is constituted, and the paired roll die includes upper roll die
With lower roll die.
The preparation facilities of the S type casing plays of described ocean flexible pipe, it is characterised in that：Paired roll die is cooperatively formed
The annular space of definite shape, flexible pipe batten is squeezed into solid shape when by annular space.
The preparation facilities of the S type casing plays of described ocean flexible pipe, it is characterised in that：Flexible pipe batten passes sequentially through five compositions
To roll die, S type casing plays are gradually formed in the presence of five groups of roll dies.
A kind of processing method of the S type casing plays of ocean flexible pipe, it is characterised in that：It uses preparation facilities as described above
It is processed, its procedure of processing is：
Step one：By the flexible pipe batten made from the upper roll die of first group of roll die and the center of lower roll die
Load, flexible pipe batten introduces roller press in the presence of first group of roll die；
Step 2：Flexible pipe batten sequentially passes through the S type flexible pipe battens that non-hasp is gradually formed after four groups of roll dies；
Step 3：The S type flexible pipe battens of non-hasp enter the 5th group of roll die under the drive of roller press, in the work of roller press
It is spirally wound under on the S type casing plays of machined completion, it is in the presence of the 5th group of roll die that the S types of non-hasp is soft
The head of pipe batten and the afterbody hasp formation ocean flexible pipe S type casing plays of last layer flexible pipe batten.
The present invention obtains cold-drawn flat band using cold-drawn, and roll forming is carried out by the mould of five groups of definite shapes.Every group
Mould is divided into two pieces of roll die and lower roll die, and upper/lower die around central shaft with certain speed by being rotated and same
When be squeezed in the cold-drawn flat of centre, change the shape of band steel by different mold shapes and be intertwined, it is final
To the S type casing plays of spiral winding.
