Anticorrosive abrasionproof protection pipeline

Technical Field

The utility model relates to a material field of carrying, more specifically relates to the pipeline design of anticorrosive abrasionproof.

Background

In industrial pipeline transportation, there are many times that materials which are highly corrosive, such as brine from salt pan, are involved. The materials are highly corrosive, alkaline or contain more salt, so that the pipeline is very easy to corrode. To prevent corrosion, more expensive corrosion resistant materials are required.

Meanwhile, some materials contain crystalline components, such as crystalline particles of salts, which are irregular in shape and have sharp corners. The inside of the pipeline is easily scratched by the materials in the pipeline conveying process, and the scratched inside of the pipeline is easily corroded by corrosive materials, so that the pipeline is easily damaged in a short time.

Replacing these pipes not only seriously affects production and operation and increases maintenance costs, but also negatively affects the health of maintenance personnel.

The utility model provides a protection pipeline of anticorrosive abrasionproof, include: an inner tube for conveying material; the outer pipe is coated outside the inner pipe, and a cavity is formed between the outer pipe and the inner pipe; when the inner tube is penetrated by the material, the material enters the cavity.

According to the utility model discloses an embodiment, the protection pipeline is the pipeline of bending.

According to an embodiment of the invention, the material is a corrosive solid-liquid mixture.

According to an embodiment of the present invention, when the material enters the cavity, it condenses to a solid state.

According to an embodiment of the present invention, the outer tube is detachable from the inner tube.

According to an embodiment of the present invention, the outer tube is integrally formed with the inner tube.

According to an embodiment of the present invention, the inner tube is a wear-resistant and corrosion-resistant material, and the outer tube is a corrosion-resistant material.

According to an embodiment of the invention, the protective pipe is entirely replaceable.

According to the utility model discloses an embodiment, be provided with transparent viewing window on the outside pipeline.

The pipeline anti-abrasion device has the beneficial effects that when materials with strong corrosivity and strong abrasion force are conveyed, the pipeline anti-abrasion device can resist corrosion and can resist abrasion, the service life of the pipeline is prolonged, the cost is reduced, and the influence on production is reduced.

Detailed Description

In the following detailed description of the preferred embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific features of the invention, such that the advantages and features of the invention may be more readily understood and appreciated. The following description is an embodiment of the claimed invention, and other embodiments related to the claims not specifically described also fall within the scope of the claims. The present invention will be described in detail with reference to the following embodiments.

Fig. 1 is a schematic view of a protective pipe according to an embodiment of the present invention.

As shown in fig. 1, the utility model discloses a protection pipeline of anticorrosive abrasionproof includes: an inner pipe 11, wherein the inner pipe 11 is used for conveying materials; the outer pipe 12 is coated outside the inner pipe, and a cavity 13 is formed between the outer pipe 12 and the inner pipe; when the inner tube 11 is penetrated by the material, the material enters the cavity 13.

The utility model discloses mainly be applied to and carry corrosive solid-liquid mixture. In such a solid-liquid mixture, the liquid portion typically contains acidic, basic, or salt-like substances, which are generally highly corrosive to the pipe, and the pipe is highly susceptible to corrosion and leakage after a period of use.

Materials that are resistant to corrosion can often be used to address this problem. On the other hand, the solid portion of the solid-liquid mixture of the above type is usually salt crystals, which have sharp corners under magnification and are very likely to scratch the pipe. And the pipeline is more easily corroded after being scratched.

In practice, simple corrosion prevention or simple wear prevention is easy to realize, but corrosion prevention and wear prevention are difficult to solve at the same time, because some materials are corrosion-resistant but not wear-resistant; while some materials are resistant to wear but not corrosion.

And the utility model discloses in, do not need the pipeline material of speciality can realize better anticorrosive abrasionproof effect. In the present invention, after the inner tube 11 is eroded and penetrated, since the cavity 13 is formed between the inner tube 11 and the outer tube, the material can enter into the cavity through the penetrated hole or opening. The cavity is gradually filled with the materials along with the continuous conveying of the materials. After a certain period of time, these materials will crystallize or form a solid state, which adheres to the inner wall of the outer tube 12, forming a protective layer. When the material continues to flow, it will no longer directly attack the pipe, but will only rub against the deposited material crystals. This will effectively protect the pipe.

In practice, the bends in the pipe are more susceptible to corrosion than straight pipes, since the material can directly impact the inner wall of the pipe. According to the utility model discloses an embodiment, the protection pipeline is the pipeline of bending.

Fig. 2 shows a schematic view of a protection pipe of the bending type according to another embodiment of the present invention.

As shown in fig. 2, the bent pipe is very easily corroded at the corner. When the material is eroded, the material enters the cavity, and as the material filled in the cavity crystallizes more and more, the erosion to the outer pipeline is small.

According to an embodiment of the present invention, the inner tube is a wear-resistant and corrosion-resistant material, and the outer tube is a corrosion-resistant material. In the utility model, the inner tube can also be made of common materials, but preferably made of more wear-resistant and corrosion-resistant materials; however, the material of the outer tube does not need to be high-cost material, but only needs to be corrosion-resistant. Since the impact force on the outer tube after the crystallization of the material filled in the cavity is small, the outer tube will have a long life as long as it can resist a certain degree of corrosion.

According to an embodiment of the present invention, the outer tube is detachable from the inner tube. This has the advantage that the outer pipe can be installed directly outside the existing pipeline and a seal is formed between the outer pipe and the inner pipe. The reconstruction does not need to destroy the existing pipeline system, and can reconstruct the existing pipeline conveniently and at low cost.

According to an embodiment of the present invention, the outer tube is integrally formed with the inner tube. According to this embodiment, can be when making the pipeline, directly form an organic whole with inner tube and outer tube to adopt when installing new pipeline the utility model discloses an integration inner tube and outer tube.

According to an embodiment of the invention, the protective pipe is entirely replaceable. The pipeline replacement device has the advantages that after a certain section of pipeline is damaged, the pipeline can be replaced integrally, and therefore the influence on normal material conveying work is reduced.

According to the utility model discloses an embodiment, be provided with transparent viewing window on the outside pipeline. The beneficial effects of this kind are that, make things convenient for maintainer to observe the damage condition of pipeline inside, when inside accumulated a large amount of crystallisates, then meant that the inner tube has damaged seriously, can consider to change the pipeline.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
