Abstract
The utility model relates to a high-pressure composite flexible vertical pipe, which is mainly used for the oil conveying in a sea oil field. The utility model comprises an inner layer, an outer layer and a reinforcing layer in the middle. The inner layer and the outer layer are made of polymers. Usually, nylon is used for the inner layer and plastic is used for the outer layer. The reinforcing layer in the middle can comprise a mixing coextrusion layer which is formed by carbon fiber and polymers and a winding layer which is made of bar steels. The outer side of the mixing coextrusion layer can be winded with two layers of carbon fiber or aramid fiber. The inner layer and the outer layer of the vertical pipe have excellent antisepsis function. The reinforcing layer has excellent strength against the inside pressure, the outside pressure and the draught. The high performance and the long service life of the vertical pipe are guaranteed. Simultaneously, because of the light weight and the moderate flexible property, the transport and the installment of the utility model are convenient.
Description
Technical field
The utility model relates to a kind of high pressure composite and flexible standpipe that is mainly used in the marine oil field oil transportation.
Background technique
Because marine oil field oil transportation standpipe need bear huge inside and outside pressure and pulling force, at present steel pipes that adopt more, the defective of this steel standpipe is that corrosion resistance is poor, working life is short, and it is big to connect difficulty, and inconvenience is installed.
The model utility content
In order to overcome the above-mentioned technological deficiency of prior art, the utility model provides a kind of high pressure composite and flexible standpipe, and this standpipe promptly has enough resistance to compressions, tensile strength, has very strong corrosion resistant ability again, and is convenient to transportation and installation.
The utility model realizes that the technological scheme of above-mentioned purpose is: a kind of high pressure composite and flexible standpipe, comprise mutual applying all-in-one-piece internal layer, skin and middle reinforced layer, described inside and outside layer is the sealing layer for being formed by the polymer pipe material all, and described centre reinforced layer comprises the winding layer that mixes coextruded layer and bar shaped steel of carbon fiber and polymer.
Internal layer of the present utility model is used for directly contacting with crude oil, outer direct same contact with sea water, therefore adopt the common polymeric seal tubing under the prior art just can play good antisepsis, the middle carbon fiber mixed coextruded layer that closes can play good tension and anti-interior pressure effect, the steel winding layer has very strong critical external compressive resistance ability again, this standpipe also can normally be used in the dark seabed of 500-600 rice, whole standpipe light weight of while, and have appropriate flexibility, transport and install also very convenient.
Description of drawings
Accompanying drawing is a kind of embodiment's of the utility model a cross-sectional configuration schematic representation.
Embodiment
In the embodiment that accompanying drawing provides, described high pressure composite and flexible standpipe comprises from inside to outside five layer 1,2.1,2.2,2.3,3, its middle three layer 2.1,2.2,2.3 constitute described reinforced layer, its internal layer 1 can adopt nylon or other polymer pipe materials usually, its skin 3 can adopt plastics or other polymer pipe materials usually, first layer 2.1 in the middle of it is described carbon fibers and the coextruded layer that mixes of polymer, described polymer can adopt nylon, polyethylene, polyvinyl chloride, polyurethane, the polymer of ABS or other any suitable, the second layer 2.2 is to be wrapped in single or multiple lift carbon fiber or the aramid fibre that mixes the coextruded layer outside, usually can twine two-layer, the 3rd layer 2.3 is winding layers of described bar shaped steel, and described bar shaped steel can be circular, rectangle, the bar steel or the shaped steel of U type or other arbitrary shapes.
Under prior art, can be used to make the of a great variety of the polymer of body or macromolecular material, various polymer pipe materials all can be used for the utility model, the variation of various polymer or macromolecular material or replace and do not influence enforcement of the present utility model.
