Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] see figure 1 , the embodiment of the present invention includes:

[0013] A multi-functional welded steel pipe, comprising a pipe body 1 bent by a steel plate into a circular section, the interface of the pipe body 1 is a triangular notch groove 2, and a straight weld seam is formed by welding along the triangular notch groove 2.

[0014] Preferably, the multifunctional welded steel pipe contains 0.03-0.10% C by mass, 0.02-0.50% SI and 0.8-2.2% MN.

[0015] Preferably, the multifunctional welded steel pipe a...

Abstract

The invention discloses a multifunctional welding steel pipe which comprises a pipe body. The pipe body is formed by bending a steel plate into the annular section. The connector portion of the pipe body is provided with a triangular notch groove, and welding is carried out along the triangular notch groove so that a linear type welding seam can be formed. The multifunctional welding steel pipe comprises, by mass percent, 0.03-0.10% of C, 0.02-0.50% of SI and 0.8-2.2% of MN. The multifunctional welding steel pipe is high in welding seam strength and corrosion resistance, and long in service life.

Description

technical field [0001] The invention relates to a multifunctional welded steel pipe. Background technique [0002] Steel pipe is a commonly used material for industry and life, but ordinary steel pipes are not enough in terms of special mechanical strength and corrosion resistance, and the weld fastness is not enough, so it needs to be improved. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a multifunctional welded steel pipe, which has high weld seam strength, strong corrosion resistance and long service life. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a multifunctional welded steel pipe, which includes a pipe body bent into a circular cross-section by a steel plate, and the interface of the pipe body is a triangular notch groove, along which the triangular Notched slot welding creates a straight weld. [0005] In a ...
