Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a steel pipe with excellent corrosion resistance. Background Art

[0002] Steel pipe is a tubular product made of steel. It is a commonly used pipeline material with advantages such as high strength, pressure resistance and corrosion resistance. When steel pipes with excellent corrosion resistance are used in the chemical industry, petroleum, natural gas and other fields, the height of the steel pipe needs to be adjusted accordingly according to actual needs.

[0003] The Chinese patent "A high-precision steel pipe with strong corrosion resistance" authorization announcement number "CN 219432788U" uses anti-rust oil material in the corrosion-resistant layer to improve the corrosion resistance of the outer part of the pipe body.

[0004] However, when the steel pipe is operating in the soil, the particles, sand and gravel in the soil will wear the anti-rust oil material on the surface of the steel pipe, thereby affecting the corrosion resistance of the steel pipe.

[0005] Therefore, a steel pipe with excellent corrosion resistance is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a steel pipe with excellent corrosion resistance in order to solve the above problems, thereby improving the problem that the corrosion resistance of the steel pipe is not high.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a steel pipe with excellent corrosion resistance, comprising: a pipe, the surface of which is provided with telescopic cylinders distributed in equal rows; a protective mechanism, the protective mechanism for protecting the pipe surface is provided at the top of the telescopic cylinder; wherein the protective mechanism comprises a mounting plate fixedly connected to the top of the telescopic cylinder, the surface of the mounting plate is clamped with two sleeves, the inner wall of the sleeve is fixedly connected with a reinforcing rod, the surface of the sleeve is rotatably connected with rollers distributed in an annular manner, and the inner wall of the mounting plate is provided with a mounting assembly. The sleeve is used to protect the surface of the pipe, and the wear of the pipe surface by the soil is blocked, thereby improving the corrosion resistance of the steel pipe. The reinforcing rod and the roller are used to protect the sleeve, reduce the wear of the sleeve surface by the soil, and improve the service life of the sleeve.

[0008] Preferably, the mounting assembly includes a slider slidably connected to both sides of the inner wall of the mounting plate, one side of the slider is fixedly connected to a mounting rod, and the surface of the mounting rod is clamped to the inner wall of the sheath. The slider and the mounting rod are used to fix the two sheaths to each other, thereby achieving the wrapping of the two sheaths on the surface of the steel pipe, thereby ensuring the protection of the surface of the steel pipe.

[0009] Preferably, a connecting rod is fixedly connected to one side of the sliding block, and a surface of the connecting rod is slidably connected to an inner wall of the mounting plate.

[0010] Preferably, the inner wall of one of the mounting plates is rotatably connected to a screw rod, and the inner wall of one of the sliding blocks is threadedly connected to the surface of the screw rod.

[0011] Preferably, the surface of the mounting rod is fixedly connected with annular mounting blocks, and the surface of the mounting blocks is clamped to the inner wall of the sheath. The mounting blocks are used to achieve friction between the mounting rod and the sheath, ensuring the stability of the mounting rod clamped to the sheath.

[0012] Preferably, a connecting ring is fixedly connected to one side of one of the sliders, and the surface of the connecting ring is slidably connected to the inner wall of the mounting plate. By using the screw rod, the connecting rod and the connecting ring, four groups of mounting rods are simultaneously moved and snapped into the sheath, thereby realizing the rapid fixing of the two sheaths on the mounting plate.

[0015] The beneficial effects of the utility model are:

[0016] 1. The sheath is used to protect the surface of the pipeline, which blocks the wear of the soil on the pipeline surface, thereby improving the corrosion resistance of the steel pipe. The reinforcing rod and the roller are used to protect the sheath, reduce the wear of the soil on the sheath surface, and increase the service life of the sheath. The slider and the mounting rod are used to fix the two sheaths to each other, thereby realizing the wrapping of the two sheaths on the surface of the steel pipe, thereby ensuring the protection of the surface of the steel pipe;

[0025] The telescopic tube 2 includes a telescopic rod and a telescopic sleeve. The surface of the telescopic rod is slidably connected to the inner wall of the telescopic sleeve. The inner wall of the telescopic sleeve is threaded with a screw. The surface of the telescopic rod is provided with threaded holes distributed in equal rows. The surface of the screw is threadedly connected to the inner wall of one of the threaded holes.

[0026] When the surface of the steel pipe needs to be protected, the two sleeves 32 are clamped against the steel pipe, and the mounting plate 31 is clamped into the sleeve 32. At this time, the mounting rod 352 is driven to move and clamp into the sleeve 32, so that the two sleeves 32 are fixed on the pipe 1. The sleeve 32, the roller 34 and the reinforcing rod 33 protect the surface of the pipe 1 and prevent the soil from wearing the surface of the pipe 1.
