Abstract
The invention relates to a manufacture process of a hose used for transmitting oceanic special media and a construction method thereof. The hose structures designed at present have three layers which are respectively inner tube layers, steel belt layers and outer tube layers, wherein the number of the steel belt layers is 12; each two layers is wounded in certain axial angles of inner pipes, whereas the winding directions of two adjacent layers are opposite, thereby enabling the pipes to be in torsion balancing states. The outer pipe layers are coated on the steel belt layers and are protection layers of the hose. Moreover, the hose structure can be changed according to the engineering requirements without changing the original hose manufacture process and method, and the three-layer structure designed at present can be changed into a five-layer structure or more than five-layer structure, and thereby, the hose manufactured by the invention can achieve the goal of higher-pressure transmission. The invention has the advantages that the problem of the corrosion of traditional steel pipes can be solved, and the hose can be processed into a continuous pipeline according to construction requirements, thereby reducing the difficulties brought to maintenance because of numerous nodes to the highest degree.
Description
Technical field
The invention belongs to the pipeline that the Yu Haiyang special media is carried.
Background technique
The traditional mode of movement of ocean special media (oil, gas etc.) is to adopt steel pipe, and mono-layer tube and bimetallic tube are arranged, and mono-layer tube is generally used for gas transmission or water, so steel-pipe construction is simple relatively.And bimetallic tube is managed and outer tube in being divided into, and the annular space fill insulant material between two pipes to reduce the loss of crude oil temperature, guarantees the mobile performance of crude oil.Because the steel pipe segmentation need dock when at sea constructing, thereby the tie point quantity of whole piece pipeline is a lot, construction process is also complicated with respect to flexible pipe, the duration is also long.In addition because the particularity of fed sheet of a media, steel pipe aspect anticorrosive a little less than, bring certain difficulty for later maintenance.
Summary of the invention
Because the conventional steel operating expenses is higher, and is subjected to the influence of workboat working days bigger, also many with respect to its construction resource that takies of installation of flexible pipe, the duration is also long; Therefore in order in time to be gone into operation or to resume production in the oil field, then can adopt composite soft tube to replace conventional steel, and flexible pipe self also have many advantages such as joint is few, operating expenses is low, speed of application is fast.
The invention has the beneficial effects as follows the etching problem that has not only effectively solved conventional steel, and can be processed into continuous pipe, farthest reduced because the numerous difficulties of bringing to maintenance of node according to construction requirement.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 has shown the interior pipe layer of flexible pipe;
Fig. 2 has shown the steel belt layer of flexible pipe;
Fig. 3 has shown the external tube layer of flexible pipe.
Wherein manage layer in the 1-; The 2-steel belt layer; The 3-external tube layer; Two layers of 4-steel bands; 5-coats two layers; The 6-towing/anchor handling/supply vessel; 7-flexible pipe release dish; 8-door shape is hung; The 9-burying machine; The 10-water surface; The 11-seabed
Embodiment
Described flexible pipe is formed by three layers, below will from inside to outside describe each layer of flexible pipe.
Among Fig. 1, interior pipe layer is covered by steel belt layer, and the relative tube's axis of steel belt layer coats to the winding angle between 80.5 degree with 79.5 degree, and the winding steel number of plies of present design is 12 layers, steel belt layer provides axially and the intensity of hoop for pipe, pipe laminar surface in steel belt layer will cover fully.
Among Fig. 2, steel belt layer is 12 layers of structure, after managing layer in wherein 1,2 layer of steel band twines, 3,4 layers of steel belt layer twines along the direction opposite with 1,2 layer of steel band, because oppositely, 3,4 layers of steel band provide the moment of torsion that causes with 1,2 layer of steel band opposite moment of torsion, thereby the pipe layer keeps the balance state in making.5,6 layers of steel band twine again the other way around, and after having twined, the 7th layer then twines with moulding band, and winding direction is consistent with 5,6 layers of steel band direction, and the relative pipeline of winding angle be 78 spend spend to 79 between, mould and be with upper track limit and Xia Dao limit overlapping about 1/3rd.Finish mould band and twine after, 8,9 layers of steel band twine with moulding the belt opposite direction, 10,11 layers of steel band are identical with 3 to 6 layers of steel band with canoe with 12,13 layers of steel band effect.Twine 14 layers at last and mould band, promptly finish steel belt layer and twine.Figure is modular design, exposes local total energy between every adjacent steel belt and forms the rhombus gap.
Among Fig. 3, after steel belt layer had twined, certain thickness clad covered steel belt layer fully, and this layer also is external tube layer for the final layer of flexible pipe, and external tube layer can add the look mother, thereby makes flexible pipe have shades of colour.In addition, this layer provides protection for interior pipe layer, and plays the fixedly effect of steel belt layer.
As the needs high-voltage tube, can change said structure into five-layer structure, promptly in pipe layer, steel band one deck (6 layers), coat one deck, steel band two layers (6 layers), coat two layers, as shown in Figure 4, can satisfy the needs that high-voltage tube designs.
When if medium is oil, needing increases thermal insulation layer in the hose construction layer, and thermal insulation layer can be in the inner or outside winding of clad, and thermal insulation layer can be made by foam or thermal insulating material.
Among Fig. 5,, need be equipped with the distinctive construction equipment of a cover at sea when constructing, return with limit pipe laying, limit ditching, the limit of realizing flexible pipe and bury three operations and carry out simultaneously, thereby flexible pipe can be laid fast to the seabed in conjunction with the characteristics of flexible pipe self.This cover construction equipment mainly contains: burying machine 9, a door shape hang 8, flexible pipe release dish 7 etc.Work progress is at first transformed towing/anchor handling/supply vessel 6, and door shape is hung 8 and is mounted to the stern place, so that transfer and reclaim burying machine 9.Afterwards flexible pipe release dish 7 is mounted on towing/anchor handling/supply vessel 6 decks, this release dish 7 is equipment specials of flexible pipe, is furnished with the controlled hydraulic motor, with the rotating speed of control release dish 7.After the flexible pipe of finished product is installed on the release dish 7, flexible pipe one end passes burying machine 9 and by the diver it is connected with initial platform standpipe end, after finishing, towing/anchor handling/supply vessel 6 navigates by water along route, burying machine 9 is under the traction of towing/anchor handling/supply vessel 6, start burying machine 9 ditchings, control release dish 7 simultaneously and transfer flexible pipe, carry out flexible pipe and lay.After the flexible pipe on the release dish 7 has been transferred, need carry out flexible pipe and cross the oceangoing ship operation, finish flexible pipe butt joint after, continue to lay, until goal platform standpipe end, the diver is connected flexible pipe with it, promptly finishes the submarine laying of whole piece flexible pipe.
