Abstract
The utility model discloses a small-bore steel band plastic composite hose construction used in a shallow sea. A composite hose is constituted by an inner liner (1), a metal enhancement layer (2), an isolation layer (3), a metal protective layer (4) and a non-metal protective layer (5). The inner liner, the isolation layer and the non-metal protective layer are shaped by continuously extruding the macromolecular polymer. The metal enhancement layer and the metal protective layer are formed by the multilayer spiral winding of metal bands. The winding manner is the overlapped winding of metal bands of two layers in the same direction or the intersected winding of metal bands of two layers in the forward and reverse directions. In addition, the five-layer structure in the present design can be changed into a structure having more layers without changing the original composite hose manufacturing process and method, thereby the goal of transport under higher pressure can be achieved. By using the small-bore steel band plastic composite hose construction provided in the utility model, the corrosion problem of traditional steel pipes can be effectively solved, continuous pipeline can be machined according to the construction requirements, and the difficulties in the construction and the maintenance on later stage caused by a plurality of nodes can be reduced to the greatest extent.
Description
Technical field
The utility model belongs to the pipeline that the ocean 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 complicated, 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 the maintenance in construction and later stage.
Summary of the invention
Because the conventional steel operating expenses is higher, and receives the influence of workboat working days bigger, also many with respect to its construction resource that takies of installation of composite soft tube, the duration is also long; Therefore in order can be gone into operation or to resume production as early as possible in the oil field on time, then can adopt composite soft tube to replace conventional steel, and composite soft tube self also have many advantages such as joint is few, operating expenses is low, speed of application is fast.
The utility model solves the technological scheme that its technical problem adopted: this shallow sea small-diameter steel strip composite soft tube is a kind ofly to be composited by high molecular polymer and metal tape, is made up of inside liner, metal enhancement layer, separation layer, coat of metal and on-metallic protective coating.Inside liner, separation layer and on-metallic protective coating are that high molecular polymer is through continuous extrusion.Metal enhancement layer and coat of metal are to be entwined through multi-layer helical by metal tape, and the relative tube's axis of metal enhancement layer coats with the winding angle between 79.5 degree to 80.5 degree; The metal enhancement layer is 6 layers of structure, and after wherein 1,2 layer of steel band twined inside liner, twined with 1,2 layer of opposite direction of steel band on 3,4 layers of steel band edge; 3, moulded the band winding for 4 layers, winding direction is consistent with 3,4 layers of steel band direction, and the relative pipeline of winding angle is between 78 degree to 79 degree; Mould band upper track limit and Xia Dao limit overlapping about 1/3rd; 5,6 layers of steel band are with to mould the belt winding direction opposite, and last one deck is moulded band and twined, and direction is consistent with 5,6 layers of direction.Coat of metal is 2 layers of structure; 1,2 layers of relative tube's axis of steel band coat separation layer with the winding angle between 79.5 degree to 80.5 degree, and 1,2 layer of steel band twines one deck again and mould band after accomplishing and twining; Winding direction is consistent with 1,2 layer of steel band winding direction; The relative pipeline of winding angle is between 78 degree to 79 degree, and it is overlapping about 1/3rd to mould band upper track limit and Xia Dao limit, and coat of metal will cover insulation surface fully.
The beneficial effect of the utility model is: not only effectively solved the etching problem of conventional steel, and can be processed into continuous pipe according to construction requirement, farthest reduced because the numerous difficulties of bringing for construction and later period maintenance of node.

Embodiment
Described composite soft tube is formed by five layers, below will from inside to outside once explain each layer of composite soft tube.
Among Fig. 1; Inside liner 1 has played the effect of corrosion protection, leakage proof, and inside liner 1 is covered by metal enhancement layer 2, and the winding angle between metal enhancement layer 2 relative tube's axis are spent to 80.5 with 79.5 degree coats; Winding metal enhancement layer 2 numbers of plies of design are 6 layers at present; Metal enhancement layer 2 bears in the pipeline and presses and external pressure for composite soft tube provides axially and the intensity of hoop, and metal enhancement layer 2 will cover liner surface fully.
Among Fig. 2; Metal enhancement layer 2 is 6 layers of structure; After wherein 1,2 layer of steel band twined inside liner, twined with 1,2 layer of opposite direction of steel band on 3,4 layers of steel band edge, because reverse; 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 make inside liner keep the balance state.When 3,4 layers twined after, then 3,4 layers are twined with moulding band, winding direction is consistent with 3,4 layers of steel band direction, and the relative pipeline of winding angle is between 78 degree to 79 degree, moulds band upper track limit and Xia Dao limit overlapping about 1/3rd.After completion is moulded band and is twined, 5,6 layers of steel band with mould the belt opposite direction and twine.Twine one deck at last again and mould band, direction is consistent with 5,6 layers of direction, promptly accomplishes metal enhancement layer 2 and twines.
Among Fig. 3, after metal enhancement layer 2 had twined, certain thickness separation layer 3 covered metal enhancement layer 2 fully.This layer provides protection for inside liner, and plays the effect of fixing metal enhancement layer 2, prevents the friction between metal enhancement layer 2 and the coat of metal 4.
Among Fig. 4; Coat of metal 4 is 2 layers of structure, and 1,2 layer of relative tube's axis of steel band coats separation layer with the winding angle between 79.5 degree to 80.5 degree, after 1,2 layer of steel band twines and accomplish; Twine one deck again and mould band; Winding direction is consistent with 1,2 layer of steel band winding direction, and the relative pipeline of winding angle is between 78 degree to 79 degree, moulds band upper track limit and Xia Dao limit overlapping about 1/3rd.Coat of metal 4 will cover insulation surface fully, thereby composite soft tube has been played the effect of protecting against shock, anti-wear, anti-external pressure and increase counterweight.
Among Fig. 5, after coat of metal 4 twined and accomplishes, certain thickness on-metallic protective coating 5 covered coat of metal 4 fully.This layer also is external tube layer for the outermost surface of composite soft tube, and external tube layer can add the look mother, thereby makes composite soft tube have shades of colour.This layer has not only played corrosion-resisting function to composite soft tube, but also has played the effect of fixing metal protective layer 4.
When if medium is oil, needing increases thermal insulation layer in the composite soft tube construction layer, and thermal insulation layer can twine between metal enhancement layer 2 and the separation layer 3 or between coat of metal 4 and on-metallic protective coating 5, and thermal insulation layer can be processed by foam or thermal insulating material.
