Abstract
The utility model relates to an alloying electrochemical anti-corrosion tube. The alloying electrochemical anti-corrosion tube comprises a tube body (1). An iron-aluminum-magnesium-tombarthite multi-component alloy layer is plated on the outer wall of the tube body (1) and a nanometer anti-corrosion coating (3) is arranged on the inner wall of the tube body (1). The alloying electrochemical anti-corrosion tube has the advantages of good anti-corrosion property, self-cathode polarization, little tube resistance and long service life.
Description
Technical field
The utility model relates to the oil field and recovers the oil and used a kind of oil pipe or the collector and delivery pipe in oil transportation field a kind of specifically alloyage electrochemical anti-corrosive pipe.
Background technique
Utilize steel pipe that liquid is gathered and transported during oil recovery, pipeline burn into perforation phenomenon can occur being in for a long time under the corrosive environment, cause pipeline not reach and promptly can not re-use service life.And on-the-spot present applied pipeline corrosion protection method major part is the coating surface the isolation method; Wherein organic coating mainly contains multiple organic anti-corrosive coating such as coal tar enamel, petroleum tar, epoxide coal bituminous, fusion epoxy powder, and these organic coatings are all thicker, and wherein the thermosetting coating is fine and close; But coating generally exists anti-mechanical shock, anti-machinery to scratch the problem of poor performance; Anticorrosive coat can damage when construction and carrying, has a strong impact on antiseptic effect, has reduced the working life of pipeline.And general electrochemical anti-corrosive method usually receives technical limitations, uses lessly, and it is many to add impressed current method cost height, technical sophistication, applying constraints, and the sacrificial anode protection polarization potential is inhomogeneous, usually stolen, has problems.
Summary of the invention
The deficiency that existing oil pipe and collector and delivery pipe antiseptic property are poor in order to overcome, working life is short; The utility model provides a kind of alloyage electrochemical anti-corrosive pipe, and this alloyage electrochemical anti-corrosive pipe has the characteristics of excellent corrosion resisting performance,, long service life little from cathode polarization, pipe resistance.
The technological scheme of the utility model is: a kind of alloyage electrochemical anti-corrosive pipe, comprise tube body, and wherein, described tube body outer wall is coated with zinc-aluminum-magnesium rare earth multicomponent alloy-layer, and the tube body inwall has nanometer anticorrosive coating.
Described tube body reaches-0.85V from cathodic polarization potential; The thickness of zinc-aluminum-magnesium rare earth multicomponent alloy-layer is 70～110 μ m; Nanometer anticorrosive coating thickness is 40～80 μ m.
The beneficial effect of the utility model is: the multicomponent alloy layer of this oil pipe or collector and delivery pipe and body form metallurgy combination, strong adhesion, and have from the cathode polarization effect, have higher mechanical strength and corrosion resistance; Simultaneously, oil pipe or collector and delivery pipe inwall carried out the nano paint rotary spraying after, this tube surfaces is bright, smooth, free of pinholes; Inner wall smooth, resistance are little, and antiseptic property is strong.
Description of drawings
Fig. 1 is the structure sectional view of the utility model.
1-tube body among the figure, 2-zinc-aluminum-magnesium rare earth multicomponent alloy-layer, 3-nanometer anticorrosive coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, this alloyage electrochemical anti-corrosive pipe comprises the body 1 of oil pipe or collector and delivery pipe, and body 1 outer wall of oil pipe or collector and delivery pipe is coated with zinc-aluminum-magnesium rare earth multicomponent alloy-layer 2, and body 1 inwall of oil pipe or collector and delivery pipe has nanometer anticorrosive coating 3.The thickness of zinc-aluminum-magnesium rare earth multicomponent alloy-layer 2 is 70～110 μ m; Nanometer anticorrosive coating thickness is 40～80 μ m.
This oil pipe or collector and delivery pipe have good corrosion resistance, and can guarantee the construction, the transportation process outer surface not aliquation, do not come off; Be mainly used in gather displacement of reservoir oil well, ternary displacement of reservoir oil well, injection gas displacement gas well, deep-etching, strong fouling well, serious waxing in production well, ground profit collection is defeated.
