Abstract
The invention relates to an anti-corrosion ring and an application method thereof. The anti-corrosion ring solves the technical problem that a screw thread end face of an existing petroleum pipeline can be corroded by petroleum easily, and comprises a ductile bed, wherein an anti-corrosion layer is arranged on the outer side of the ductile bed; the ductile bed is made of plastics. The anti-corrosion ring and the application method thereof are widely applied in the field of oil exploitation and transportation.
Description
Technical field
The present invention relates to a kind of pipeline erosion protection system, particularly relate to a kind of anticorrosion circle and using method thereof.
Background technique
As everyone knows, oil is one of necessary fossil energy of mankind's socio-economic development.In by pipeline, exploiting, transport the process of oil, due to the physical property of oil itself, oil meeting corrosion pipeline, cause pipeline aging, damaged, causes heavy economic losses.
For this reason, people have used the whole bag of tricks to prevent that pipeline is corroded, and existing anti-corrosion method is mainly to apply the strong coating of corrosion resistance on pipeline, internal surface of sleeve pipe.Yet for screwed connection, pipeline together exists the protection of screw thread end face obviously inadequate to this method, the technical problem that the screw thread end face is easy to be corroded.Cause the main cause of this result to comprise: the spraying coating process difficulty of the coating on (1) screw thread end face is very large; (2) when go into the well in scene, operator do not carry out according to working specification fully, do not realize the sealing of male and female end end face; (3) when go into the well in scene, operator fully evenly do not smear screw thread sealing ester.
Summary of the invention
The present invention, for the technical problem that the screw thread end face that solves existing petroleum pipeline is easily corroded by oil, provides a kind of anticorrosion circle and using method thereof that can effectively prevent that the screw thread end face is corroded.
The present invention includes ductile bed, the ductile bed outside is provided with anticorrosive coat, and ductile bed is made of plastics.
Preferably, plastics are the PVC material.
Preferably, the thickness of ductile bed is 1mm～6mm.
Preferably, the thickness of ductile bed is 2mm.
Preferably, the axial cross section of ductile bed is trapezoidal, and these two trapezoidal waists are circular arc.
The present invention also provides a kind of using method of anticorrosion circle: first by anticorrosion snare on the screw thread end face of body; Again body is heated to 180 ℃～260 ℃, keeps this temperature 1min～20min, make the ductile bed fusing; Then stopping heating making body cooling.
Preferably, the body temperature is 210 ℃, keeps 12min.
The invention has the beneficial effects as follows, ductile bed is subject to the male end screw thread, to be bonded into after thermal softening, cooling closely link together afterwards, final and end face becomes one, so just screw thread end face and oil are just cut off and opened, the screw thread end face can not come in contact with oil, can not be subject to the corrosion of oil; Anticorrosive coat is anti-corrosion layer, with oil, directly contacts; Ductile bed is used the high PVC material of plasticity, melt cooling after and the combination force of screw thread end face very large, be not easy to come off.
Further aspect of the present invention, will, in the description of following embodiment, clearly be put down in writing.
The accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is the sectional view of A-A direction in Fig. 1;
Fig. 3 is that the present invention uses view.
The reference numeral explanation:
1. ductile bed, 2. anticorrosive coat, 3. body, 4. screw thread.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes ductile bed 1, ductile bed 1 outside is provided with anticorrosive coat 2, and ductile bed 1 is internal layer, and anticorrosive coat 2 is outer.
What anticorrosive coat 2 was used prior aries has material anticorrosion, sealing characteristics, for example modified poly ethylene or a modified PVC.
As shown in Figure 3, during use, be ready to the petroleum pipeline with screw thread, the present invention is enclosed within on the end face of screw thread 4 of body 3, body 3 is heated to 180 ℃～260 ℃, keeps this temperature 1min～20min, make ductile bed 1 fusing, then stop heating and make body 3 cooling, so just ductile bed 1 and the end face of screw thread 4 are combined into one.The end face of screw thread 4 and oil just cut off and have opened, and the end face of screw thread 4 can not come in contact with oil, can not be subject to the corrosion of oil.
In order to reach best in conjunction with effect, preferably body is heated to 210 ℃, keep 12min.
The present invention not only can be used on the oil delivering pipe, and can be used in to carry and have on the pipeline of corrosive medium as sulfuric acid etc.
The above,, only to the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Every in claim limited range of the present invention, any modification of making, be equal to replacement, improvement etc., all should be within protection scope of the present invention.
