[0002] TPEP anti-corrosion steel pipe is currently the most commonly used anti-corrosion method for buried long-distance pipelines. The outer wall of TPEP anti-corrosion steel pipe adopts a three-layer anti-corrosion layer with a bottom layer of epoxy powder, an intermediate layer of adhesive and an outer layer of polyethylene through a hot-melt winding process. The inner wall adopts a hot-spray epoxy powder anti-corrosion method, which involves heating the steel pipe at high temperature and then uniformly coating the powder onto the surface of the pipe body.
[0003] In the existing technology, the installation of traditional anti-corrosion steel pipes may involve cumbersome disassembly steps, which directly leads to a significant increase in the time cost required for replacement and indirectly leads to a significant decrease in the work efficiency of the staff. In the existing technology, after a long period of use, the coating on the surface of some anti-corrosion steel pipes often suffers significant wear and tear, which directly leads to a significant reduction in the service life of the anti-corrosion steel pipe and indirectly leads to a significant increase in maintenance costs. Utility Model Content

It can also solve the problem of significant wear and tear on the surface coating of some anti-corrosion steel pipes after long-term use, thus avoiding the problem of significantly reduced service life of the anti-corrosion steel pipe and significantly increased maintenance costs.
[0005] To achieve the above objectives, a convenient TPEP anti-corrosion steel pipe is provided, comprising an anti-corrosion steel pipe body, an installation head fixedly connected to the outer surface of the anti-corrosion steel pipe body, and an installation seat provided on the left side of the installation head;

[0016] 2. Compared with existing technologies, by setting a protective coating, when the coating on the outer surface of the anti-corrosion steel pipe body needs protection, the anti-corrosion steel pipe body can be better protected under the action of the protective coating material.

Detailed Implementation
[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0025] Reference Figure 1-4 This utility model provides a convenient TPEP anti-corrosion steel pipe, which includes an anti-corrosion steel pipe body 1, an installation head 2 fixedly connected to the outer surface of the anti-corrosion steel pipe body 1, and an installation seat 3 provided on the left side of the installation head 2.
[0026] A sealing ring 4 is fixedly connected to the outer surface of the anti-corrosion steel pipe body 1. A protective coating 5 is applied to the outer surface of the anti-corrosion steel pipe body 1. A slot 7 is provided inside the mounting base 3. A clearance groove 6 is provided inside the mounting base 3. The clearance groove 6 is the same size as the sealing ring 4.
[0027] A first connecting rod 8 protrudes from the side of the mounting head 2. A second connecting rod 9 is fixedly connected to the side of the first connecting rod 8. A locking block 10 is fixedly connected to the left side of the second connecting rod 9. An elastic telescopic rod 11 is provided on the side of the second connecting rod 9 away from the locking block 10. A spring 16 is provided inside the elastic telescopic rod 11. A fourth connecting rod 17 is fixedly connected to one end of the spring 16. The second connecting rod 9 is fixedly connected to the other end of the fourth connecting rod 17. A third connecting rod 12 is fixedly connected to the right side of the second connecting rod 9. A slider 13 is fixedly connected to the right side of the third connecting rod 12. A limit rod 14 is slidably connected to the inner surface of the slider 13. A connecting plate 15 is fixedly connected to one end of the limit rod 14. The two sides of the connecting plate 15 are fixedly connected to the inner wall of the mounting head 2. There are two connecting plates 15.
[0028] The above structure, by setting the installation head 2 and the installation base 3, enables the installation of anti-corrosion steel pipes. When the first connecting rod 8 needs to be pressed, it can drive the second connecting rod 9 to move longitudinally. The left side of the second connecting rod 9 is fixedly connected to the locking block 10, which can move longitudinally and enter the locking groove 7 inside the installation head 2. This avoids the problem of a significant increase in the time cost required for replacement and avoids a significant decrease in the work efficiency of the staff.
[0029] By setting the protective coating 5, when the outer surface of the anti-corrosion steel pipe body 1 needs protection, the protective coating 5 provides better protection for the anti-corrosion steel pipe body 1. The material of the protective coating 5 is epoxy resin, which has excellent corrosion resistance and can effectively prevent the steel pipe surface from being corroded by chemical media, acid and alkali substances, etc. It is especially suitable for pipelines in the oil and natural gas industries. After the epoxy resin is cured, it forms a solid surface, which helps to improve the wear resistance of the pipeline. Especially in environments where particulate matter or friction may exist during fluid transportation, epoxy resin coatings can effectively reduce surface wear and extend pipeline service life. Epoxy resin has strong adhesion to the steel pipe surface, firmly adhering to the TPEP anti-corrosion layer and is not easily peeled off. Epoxy resin has good temperature resistance, able to withstand a certain range of high and low temperatures. Epoxy resin can resist the effects of ultraviolet radiation, reducing coating aging and fading caused by exposure to sunlight. Epoxy resin coatings can effectively prevent the penetration of moisture and humidity, protecting the steel pipe from moisture erosion and reducing the risk of pipeline corrosion. As a result, the coating on the surface of the anti-corrosion steel pipe body 1 will not experience significant wear, thus avoiding a substantial reduction in the service life of the anti-corrosion steel pipe and a significant increase in maintenance costs.
[0030] Working principle: When it is necessary to install the anti-corrosion steel pipe, the first connecting rod 8 can be pressed first, so that the first connecting rod 8 can drive the second connecting rod 9 to move longitudinally. The left side of the second connecting rod 9 is fixedly connected to the locking block 10, so that the locking block 10 can move longitudinally and enter the locking groove 7 inside the installation head 2. Under the action of the protective coating 5, the anti-corrosion steel pipe body 1 can be better protected.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
