Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipes, in particular to an anti-corrosion and durable steel pipe. Background Art

[0002] As an important pillar of modern industry, seamless steel pipes have a unique performance and wide application fields, which makes them occupy a place in the market. Seamless steel pipes have become the preferred material in many industries with their high strength, excellent corrosion resistance and good weldability. With the advancement of science and technology, the manufacturing process of seamless steel pipes is also constantly innovating. Modern production lines and advanced production equipment have further improved the quality and performance of seamless steel pipes. At the same time, the industry's emphasis on environmental protection has also promoted the green development of the production process of seamless steel pipes, reducing energy consumption and environmental pollution.

[0003] Patent publication number "CN219473084U" discloses "a corrosion-resistant and durable seamless steel pipe", including a first protective pipe and a second protective pipe, which are symmetrically installed on the outer wall of the reinforcement sleeve. The positioning block and the positioning groove cooperate with each other to facilitate the positioning of the first protective pipe and the second protective pipe on the outer wall of the reinforcement sleeve. The docking plate and the fixing plate are fixed by bolts, and then the first protective pipe and the second protective pipe are fixed to the outer wall of the reinforcement sleeve, thereby providing a good protective effect on the seamless steel pipe body, so that the outer wall of the seamless steel pipe body is not easily damaged when it encounters collisions with external objects, thereby improving the service life of the seamless steel pipe body.

[0004] When the device in the above patent uses an external protective shell to protect the steel pipe, if it encounters sudden external force or collision contact, the outer shell cannot effectively reduce and buffer the impact force from the outside, which may cause the protective shell to deform and even cause the outer surface of the steel pipe to change to varying degrees. In order to improve the protective performance of the device, its protection measures should be strengthened. Utility Model Content
