Abstract
The utility model discloses a polyurea antisepsis counterweight tube, including a conduit, in addition, an antisepsis coating of single coat polyurea elastomer and a beton weight coating covered in turn on the surface of the tube. The utility model using polyurea elastomer antisepsis coating supersede the three-ply concussion, so that the process of antisepsis constructing could be simplified and the painting hour could be shortened, at the same time, the properties of peeling resistance and concussion resistance are increased owing to the oneness of the concussion, The combination of the polyurea elastomeric material and the beton coating is very strong to benefit the resistance of the slipping in the installation.
Description
Technical field
The utility model relates to a kind of novel anticorrosion structure, relates in particular to the anticorrosion counterweight pipe of a kind of polyureas, is applicable to the anticorrosion counterweight technology of submarine pipeline field.
Background technique
For the pipeline in the seabed that is laid in certain depth, rivers, lake and the marshland, the conventional way of the anticorrosion counterweight structure that adopts is at present: anticorrosion counterweight structure, i.e. " internal layer working steel tube+outer three-layer polyethylene/polypropylene is anticorrosion ".
This structure has been used long historical on the corrosion-resistant thermal insulation pipeline of ocean, but three stratas second/propylene class anticorrosion structure is last still undesirable with combining of concrete weighted coating.
Summary of the invention
The purpose of this utility model is to provide a kind of pipeline construction level that improves, the anticorrosion counterweight pipe of the submarine pipeline of excellent performance.
The utility model is achieved by the following technical programs.
The anticorrosion counterweight pipe of the utility model polyureas, it comprises pipeline, is coated on the anticorrosive coat and the concrete weighted coating of described pipe surface successively, and described anticorrosive coat is the individual layer SPUA.
The utility model structure has replaced three layers of anticorrosion structure with the SPUA anticorrosive coat, has simplified the anticorrosion construction operation, has shortened being coated with ETL estimated time of loading.Simultaneously because the monotony of anti-corrosion layer structure, improved the anti-sled stripping property and the characteristic such as shock-resistant of anticorrosive coat.The combination force of polyurea elastomer material and concrete sheath coat is very strong, is beneficial to the slippage in the opposing piping erection process.
Description of drawings
Fig. 1 is the anticorrosion counterweight pipe of a polyureas of the present utility model cross sectional representation;
Fig. 2 is the anticorrosion counterweight pipe end of a polyureas of the present utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2:
Be coated on the anticorrosive coat 2 outside the steel pipe layer 1, adopt individual layer SPUA structure;
Concrete weighted coating 4, by spraying or fashion of extrusion is coated to the outside of SPUA protective layer with concrete, form a kind of concrete layer, wherein with certain intensity and severe, in described concrete weighted coating 4, preferably be provided with back-up coat 3, adopt steel net structure to reinforce;
Through the testing property to anticorrosion counterweight pipe, the shear strength between each layer has all surpassed the 0.1N/mm2 of designing requirement.
Claims (2)
1. the anticorrosion counterweight pipe of polyureas, it comprises pipeline, is coated on the anticorrosive coat and the concrete weighted coating of described pipe surface successively, it is characterized in that described anticorrosive coat is the individual layer SPUA.
2. the anticorrosion counterweight pipe of polyureas according to claim 1 is characterized in that: be provided with back-up coat in described weight coating.
