Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe technology, and in particular to an anti-corrosion steel pipe with damage resistance function. Background Technology
[0002] Steel pipe is a type of steel with a hollow cross-section. It is mainly used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers. To improve the corrosion resistance of steel pipes, a layer of anti-corrosion tape is usually adhered to the surface of the steel pipe, which can extend the service life of the steel pipe. After the anti-corrosion tape is applied, collisions between steel pipes or between steel pipes and hoisting equipment are inevitable during transportation and assembly, which can easily damage the anti-corrosion tape. Furthermore, as the service life of the steel pipe increases, the anti-corrosion tape is also prone to falling off, which will lead to the exposure of the steel pipe surface and thus affect the corrosion resistance of the steel pipe. Utility Model Content
[0003] The purpose of this utility model is to avoid the shortcomings of the prior art and provide a corrosion-resistant steel pipe with damage resistance function, thereby effectively solving the shortcomings of the prior art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a corrosion-resistant steel pipe with anti-damage function, comprising a steel pipe body, wherein a number of raised ring ribs are evenly distributed along the circumference of the steel pipe body, and anti-corrosion tape is wrapped around the outside of the steel pipe body and the ring ribs. The anti-corrosion tape is provided with a pressure cap at the position corresponding to each ring rib, and the pressure cap is fixedly connected to the ring rib. The pressure cap is composed of two semi-circular annular pressure plates spliced together.
[0005] Furthermore, the ring rib is provided with a plurality of threaded holes along the circumferential direction, and the pressure plate is provided with through holes at the positions corresponding to each of the threaded holes. A retaining screw is provided on the outer side of the pressure plate, and the retaining screw passes through the through hole and is screwed into the threaded hole.
[0006] Furthermore, the upper and lower ends of the ring rib are positioned by a positioning shaft, which passes through the anti-corrosion tape and extends therein. The splicing end of the pressure plate is provided with a relief groove that matches the positioning shaft. The relief grooves on the two pressure plates cooperate with each other to cover the outside of the positioning shaft.
[0007] Furthermore, the two sides of the ring rib have an inclined slope structure, the corners of the ring rib are chamfered, and the shape of the pressing plate is adapted to the shape of the ring rib.
[0008] Furthermore, the circumferential reinforcement is welded to the outside of the steel pipe body.
[0009] Furthermore, the retaining screw is welded to the ring reinforcement.
[0010] The above-mentioned technical solution of this utility model has the following beneficial effects: By setting several raised ring ribs on the steel pipe body and arranging pressure caps at the positions of the ring ribs, the anti-corrosion tape can be fixed in place, thus preventing the anti-corrosion tape from loosening and ensuring the anti-corrosion performance of the steel pipe. In addition, the overall outward protrusion of the pressure caps can prevent direct collisions between steel pipes or between steel pipes and hoisting equipment, thus avoiding damage to the anti-corrosion tape, improving the damage resistance of the steel pipe, and greatly improving the overall performance of the steel pipe.

[0016] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0018] like Figure 1-5 As shown in the figure, the anti-corrosion steel pipe with damage resistance function described in this embodiment includes a steel pipe body 1. Several raised ring ribs 2 are evenly distributed along the circumference of the steel pipe body 1. Anti-corrosion tape 3 is wrapped around the outside of the steel pipe body 1 and the ring ribs 2. The anti-corrosion tape 3 is provided with a pressure cap at the position corresponding to each ring rib 2. The pressure cap is fixedly connected to the ring rib 2. The pressure cap is spliced together by two semi-circular ring pressure plates 4.
[0019] The ring rib 2 has several threaded holes along its circumference. The pressure plate 4 has through holes at the corresponding positions of the threaded holes. The pressure plate 4 has a retaining screw 5 on its outer side, which passes through the through holes and is screwed into the threaded holes.
[0020] A countersunk hole can also be arranged on the outer side of the pressure plate 4 at the position corresponding to the perforation. The head of the retaining screw 5 is located in the countersunk hole. In this way, the countersunk hole can be hidden inside the pressure plate 4, thereby avoiding the head of the retaining screw 5 from protruding outward and being damaged by collision.
[0021] The upper and lower ends of the ring rib 2 are positioned by a positioning shaft 6. The positioning shaft 6 passes through the anti-corrosion tape 3 and extends therein. The splicing end of the pressure plate 4 is provided with a relief groove 7 that matches the positioning shaft 6. The relief grooves 7 on the two pressure plates 4 cooperate with each other to cover the outside of the positioning shaft 6.
[0022] The arrangement of the two positioning shafts 6 facilitates the fixed installation of the pressure plate 4. The two ends of the two pressure plates 4 are connected, and the relief grooves 7 at the ends of the two pressure plates 4 are connected with the positioning shafts 6, thereby realizing the quick connection of the two pressure plates 4. It also ensures that the through holes on the pressure plate 4 and the threaded holes on the ring rib 2 can be connected, which facilitates the installation of the fixing screw 5. The positioning shaft 6 is covered inside by the relief grooves 7 to prevent the positioning shaft 6 from being exposed.
[0023] The two sides of the ring rib 2 are inclined slope structure, and the corners of the ring rib 2 are chamfered. The shape of the pressing plate 4 is adapted to the shape of the ring rib 2.
[0024] The ring reinforcement 2 is welded to the outside of the steel pipe body 1.
[0025] The retaining screw 5 is welded to the ring reinforcement 2.
[0026] When the steel pipe is subjected to anti-corrosion treatment, the anti-corrosion tape 3 is first wrapped around the outside of the steel pipe body 1, and the anti-corrosion tape 3 is wrapped together with the ring rib 2. The positioning shaft 6 on the ring rib 2 passes through the anti-corrosion tape 3, and the anti-corrosion tape 3 is drilled at the corresponding threaded hole positions. Then, two pressure plates 4 are joined together and wrapped around the ring rib 2. The relief groove 7 at the end of the pressure plate 4 abuts against the positioning shaft 6 at the upper and lower ends. Then, the pressure plate 4 is fastened to the ring rib 2 using the fixing screw 7. In this way, multiple pressure plates cover and tighten the anti-corrosion tape 3, thereby preventing the anti-corrosion tape 3 from falling off, which can greatly improve the performance of the steel pipe.
[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
