Embodiment Construction

[0013] Such as figure 1 As shown, a high-strength steel pipe of the present invention includes a pipe body 1 , an adhesion layer 2 and an anti-wear layer 3 . The anti-wear layer 3, the adhesion layer 2, and the pipe body 1 are arranged sequentially from inside to outside. The wear-resistant layer 3 consists of a polyisocyanate coating.

[0014] The construction process of this example: the polyisocyanate is attached to the inner wall of the pipe body 1 by spraying, and the adhesive layer 2 is used to form a whole.

[0015] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention, and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the present invention shall still belong to the scope covered by the patent of the present invention.

Abstract

The invention provides a high-strength steel pipe. According to the technical scheme, the high-strength steel pipe comprises a pipe body, and is characterized by further comprising an adhesion layer and an antiwear layer, wherein the antiwear layer, the adhesion layer and the pipe body are arranged in sequence from inside to outside, and the antiwear layer is composed of a polyisocyanate coating. The high-strength steel pipe has the advantages that due to the fact that the technical scheme is adopted, the surface of the antiwear layer which is arranged on the inner side of the high-strength steel pipe is smooth, fluid resistance is low, and operating efficiency is high; the pipe body on the outer side is high in pressure-bearing capacity, resists impact, and has the good protection effect, and the service life is prolonged.

Description

technical field [0001] The invention relates to a steel pipe, in particular to a high-strength steel pipe. Background technique [0002] The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. [0003] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal, and realize factory-like mechan...
