Abstract
A composite steel pipeline comprises a pipeline body and a connecting portion. The pipeline body comprises a steel pipe, a galvanized nickel alloy coating is arranged on the outer surface of the steel pipe, an EP (epoxy) resin coating is arranged on the inner surface of the steel pipe, the connecting portion comprises a connecting pipe fitting, and the connecting pipe fitting is provided with an internal thread matched with an external thread at the end of the pipeline body. The pipeline has excellent corrosion resistance and decorativeness, fine mechanical property and long overall service life and is applicable to various purposes and fields of water supply, rainwater collecting delivery, sewage delivery, food processing, medical treatment, machinery and the like, and the corrosion resistance of the pipeline is 2-4 times that of a hot-dip galvanized pipe.
Description
Technical field
The utility model relates to pipeline connection technology field, especially relates to a kind of external galvanized layer nickel alloy internal plastic coating Composite Steel pipeline.
Background technique
Tradition water supply and sewerage pipeline is generally galvanized pipe, this pipe has good intensity, rigidity and impact resistance, but in use because its corrosion-resistant, corrosion are serious, and easily fouling, grow microorganism, cause the bad phenomenon such as bacterium in water exceeds standard, fouling obstruction, especially in its shorter working life, increased especially pipe-line maintenance expense.
Although fiber reinforced plastic pipe is a kind of lightweight, high-strength, corrosion resistant pipeline, it is successively wrapped according to technological requirement by the glass fibre of resin base body weight on the core of rotation and makes, and can between fiber, spread equably at a distance silica sand as burning into sand layer to increase its intensity.In any case but fiber reinforced plastic pipe improve, all can not reach the mechanical strength of metal pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of Composite Steel pipeline, this pipeline external surface has zinc-plated nickel dam, internal surface is EP resinous coat, not only there is good mechanical property, and there is good corrosion resistance and longer working life, the technological scheme adopting is: Composite Steel pipeline, comprise pipeline body and attachment portion, it is characterized in that: described pipeline body comprises steel pipe, on outer surface of steel tube, there is zinc-nickel alloy coating, on the internal surface of steel pipe, there is EP resinous coat, described attachment portion comprises connection pipe fitting, described connection pipe fitting has the internal thread coordinating with the outside thread of pipeline body end.
The beneficial effects of the utility model are: 1) this pipeline body inwall is the coating that high temperature welding nontoxic high molecular special powder forms, and outer surface is the zinc-nickel layer first re-plating after steel pipe polishing treatment being formed, coating silvery white light, careful; 2) this pipeline has excellent corrosion resistance, and the 2-4 that corrosion resistance is hot dip galvanizing pipe doubly; Excellent is ornamental; Mechanical property and longer pipeline whole service life preferably, is suitable for using in multiple use and fields such as water supply, rainwater-collecting conveying, sewage transport, food processing, medical treatment, machineries.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, and wherein I is pipeline body, and II is attachment portion, the 1st, and zinc-nickel alloy coating, the 2nd, EP resinous coat.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.The utility model discloses a kind of Composite Steel pipeline, comprise pipeline body I and attachment portion II, by attachment portion II, pipeline body I is connected, obtain needed duct length.Pipeline body I comprises steel pipe, has zinc-nickel alloy coating 1 on outer surface of steel tube, has EP resinous coat 2 on the internal surface of steel pipe.Attachment portion II comprises connection pipe fitting, and connection pipe fitting has the internal thread coordinating with the outside thread of pipeline body I end processing, by the cooperation of internal and external screw thread, different pipeline bodies is connected.
Pipeline body I adopt steel pipe be processed into, first, outer surface of steel tube need be carried out to polishing treatment, consider environmental requirement, this polishing treatment process using shot-blasting machine.Secondly, by electroplating machine electroplated zinc nickel alloy coating.Finally, be also the key of this pipeline body processing, be to process EP resinous coat 2 and used plastic-coated steel production line, plastic-coated steel production line comprises following part successively: input part; Warming portion; Well chamber plastic-coated part, EP toner is suspended in well chamber; Secondary heating part, is incubated the pipeline body after plastic-coated at 150 ℃; Force cooling segment; Output.By input part, steel pipe to be processed is inputted, steel pipe is heated to 300-350 ℃ by warming portion, steel pipe after heating is delivered to well chamber plastic-coated part and carries out plastic-coated processing, the plastic-coated using uses powder suspension in well chamber, and be combined in steel tube surface, steel pipe output after plastic-coated, and be incubated force after certain hour cooling, this is cooling can be air-cooled or water-cooled, finally output.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also belong to protection domain of the present utility model.
