Drawings
Fig. 1 is a schematic cross-sectional view of the structure of the present invention.
In the figure: the seamless steel tube comprises a seamless steel tube body 1, a second octagon 2, a first octagon 3, a heat insulation layer 4, a wear-resistant isolation layer 5, a concave edge 6, an outer convex edge 7 and a corrosion-resistant layer 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: high obdurability seamless steel pipe for crane boom, including seamless steel pipe main part 1, first octagon 3 has been seted up to the internal surface of seamless steel pipe main part 1, and outer chimb 7 has evenly been seted up to the internal surface of first octagon 3, and second octagon 2 has been seted up to the surface of seamless steel pipe main part 1, and indent 6 has evenly been seted up to the surface of second octagon 2.
Through the cooperation of seamless steel pipe main part 1 and first octagon 3, second octagon 2, can promote seamless steel pipe main part 1's mechanical properties.
The outer convex edge 7 is parallel to the inner concave edge 6. With first octagon 3 and the cooperation of second octagon 2, can further promote the mechanical properties of seamless steel pipe main part 1.
The inner surface of the outer flange 7 and the outer surface of the inner flange 6 are coated with a corrosion resistant layer 8. The corrosion-resistant layer 8 can isolate the outer convex edge 7 from the inner concave edge 6, and oxidation caused by contact of the seamless steel pipe main body 1 and the environment is avoided.
The outer surface of the corrosion-resistant layer 8 of the second octagon 2 is fixedly provided with a heat insulation layer 4 through resin. The heat insulation layer 4 can better isolate the influence of the external environment temperature, and the influence on the seamless steel pipe main body 1 is avoided.
The outer surface of the heat insulation layer 4 is fixedly provided with a wear-resistant isolation layer 5 through resin. The inner environment and the outer environment can be isolated through the wear-resistant isolation layer 5, and the seamless steel pipe body 1 is prevented from being corroded by wear and the external environment.
