Description
Technical field
The present invention relates to a kind of cold drawing steel tube, more particularly to a kind of double-deck fine diamond turning.
Background technology
Cold drawing steel tube is for mechanical structure, the accurate cold-drawing seamless pipe that the dimensional accuracy of hydraulic test is high and surface smoothness is good.From accurate seamless tube producer tool structure or hydraulic test etc., machining man-hour can be greatlyd save, improves stock utilization, while is advantageous to improve product quality.In the field of the liquid conveying of reality, steel pipe is typically embedded in underground or is chronically in the higher environment of water vapour content, so corrosion easily occurs and causes steel pipe to fail, reduces the service life of steel pipe.
The content of the invention
The purpose of the present invention, which is that, provides a kind of novel in structural design, reasonable, intensity height, the double-deck fine diamond turning of service life length.
To achieve these goals, the technical solution adopted by the present invention is such：The double-deck fine diamond turning of the present invention, including steel pipe body, the steel pipe body includes outer tube and inner tube, outer tube and outer wall of inner tube section are circle, outer tube and inner tube wall are regular hexagon, outer tube noose is on inner pipe, and gap is provided between outer tube and inner tube, cushion is provided with gap, the inwall of said inner tube is provided with the plastic film layer of polished processing, the outer wall of the outer tube is provided with anticorrosive coat, the end face of outer tube is provided with projection, through hole is provided with projection, the other end of outer tube is provided with the groove to match with projection, the projection communicated with through hole is provided with groove.
Preferably, the anticorrosive coat is the weather-proof anticorrosive coat of acroleic acid polyurethane.
Preferably, the convex cylindrical surface is provided with epoxy material.
Compared with prior art, the advantage of the invention is that：Novel in structural design of the present invention, rationally, steel pipe body includes outer tube and inner tube, enhance the intensity of cold drawing steel tube, cushion is set between outer tube and inner tube, avoid producing impact in installation process or in particular cases to inner tube, influence the transfer efficiency of inner tube, inner tube wall sets plastic film layer, corrosion-resistant effect can be played, it may also function as the effect of protection inner tube, outer tube outer wall sets anticorrosive coat, improve the decay resistance of steel pipe, extend the service life of steel pipe, the both ends of outer tube set projection and groove respectively, it is easily installed connection, improve installation effectiveness.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, the double-deck fine diamond turning of the present invention, including steel pipe body, the steel pipe body includes outer tube 1 and inner tube 2, outer tube 1 and the outer wall section of inner tube 2 are circle, outer tube 1 and the inwall of inner tube 2 are regular hexagon, the noose of outer tube 1 is in inner tube 2, and it is provided with gap between outer tube 1 and inner tube 2, cushion 3 is provided with gap, the inwall of said inner tube 2 is provided with the plastic film layer 4 of polished processing, the outer wall of the outer tube 1 is provided with anticorrosive coat 6, the end face of outer tube 1 is provided with projection 5, through hole 7 is provided with projection 5, the other end of outer tube 1 is provided with the groove to match with projection 5, the projection communicated with through hole 7 is provided with groove, the anticorrosive coat 6 is the weather-proof anticorrosive coat 6 of acroleic acid polyurethane, the surface of projection 5 is provided with epoxy material.
During construction, two steel pipes are connected by projection 5 with groove, it is easy for installation, and installation effectiveness is high, novel in structural design of the present invention, rationally, steel pipe body includes outer tube 1 and inner tube 2, enhance the intensity of cold drawing steel tube, cushion 3 is set between outer tube 1 and inner tube 2, avoid producing impact in installation process or in particular cases to inner tube 2, influence the transfer efficiency of inner tube 2, the inwall of inner tube 2 sets plastic film layer 4, corrosion-resistant effect can be played, it may also function as the effect of protection inner tube 2, the outer wall of outer tube 1 sets anticorrosive coat 6, improve the decay resistance of steel pipe, extend the service life of steel pipe.
