Description
Technical field
The utility model relates to a kind of water supply and sewerage pipeline, especially a kind of high pressure-bearing composite steel corrosion-resistant pipeline.
Background technique
Along with the construction in city, water supply and sewage work get more and more.The various water supply and drainage pipeline future development such as, caliber large to buried depth be large gradually, under this operating mode, the load that pipeline bears is often very large.The development of industrialized development particularly chemical industry causes increasing of chemical composition in underground water, and the groundwater corrosivity containing chlorion etc. is high, particularly very large to the corrosivity such as reinforced concrete pipiline, steel pipeline.So, how to solve pipeline configuration safety when high pressure is born at, pipeline top large at buried depth and Anticorrosion Problems becomes increasingly conspicuous.
Through finding the retrieval of prior art: the patent No.: CN201220647865.3, disclose a kind of steel and mould winding welded pipe, this effective steel plastic compount heterotypic strip spiral winding forms the pipe technology then welded, when this technology is large for buried depth, high pressure load is born at pipeline top, because weld seam is spiral helicine, suffered by weld seam, pulling force is huge, and easily cracking causes pipeline local damage and then causes the corrosion-inhibiting coating outside weld seam damaged, causes pipe leakage.When pipe applications is in discharge of wastewater, also easily cause the pollution of environment.
Summary of the invention
For the deficiencies in the prior art, the utility model to provide a kind of high pressure-bearing composite steel corrosion-resistant pipeline, improved the integral rigidity of pipeline by the technology of integral pipe outsourcing pressure-bearing steel loop, solve corrosion-resistant problem by integrated corrosion-inhibiting coating coated outside pipeline.
The technical solution adopted in the utility model is:
A kind of high pressure-bearing composite steel corrosion-resistant pipeline, comprise integral pipe body, outsourcing pressure-bearing steel loop, integrated corrosion-inhibiting coating, the outside cover of described integral pipe body has some described outsourcing pressure-bearing steel loops and the inner side of described outsourcing pressure-bearing steel loop is fixedly connected with described integral pipe body, and described integrated corrosion-inhibiting coating is wrapped in the outside of described integral pipe body and described outsourcing pressure-bearing steel loop.
Preferably, described integral pipe body is a cross section external frame is circular square or oval steel pipe.
Preferably, the inner side profilogram of described outsourcing pressure-bearing steel loop and the external frame of described integral pipe body match.
Preferably, the plane at described outsourcing pressure-bearing steel loop place and the axes normal of described integral pipe body.
Preferred, some described outsourcing pressure-bearing steel loop spaced sets.
Preferably, the composition of described integrated corrosion-inhibiting coating is polyethylene or epoxy resin, adopts hot-spraying technique to make its uniform fold in the outer surface of described integral pipe body and described outsourcing pressure-bearing steel loop.
Preferred, the thickness of the described integrated corrosion-inhibiting coating covered outside high pressure-bearing composite steel corrosion-resistant pipeline described in every root is uniformity.
The beneficial effects of the utility model are:
The utility model substantially increases its flexural rigidity by the technological means of installing outsourcing pressure-bearing steel loop outside integral pipe body, guarantees the structural safety of pipeline under heavy load.The integrated corrosion-inhibiting coating that pipeline covers outward serves the effect of anti-corrosion protection pipeline, improves the working life of pipeline.
