Description

High-strength welded pipe internally welded with multi-bent steel

Technical Field

The utility model relates to the field of steel pipes, in particular to a high-strength welded pipe internally welded with multi-bent steel.

Background

The welded steel pipe is also called welded pipe, is made by welding steel plate or strip steel after curling and shaping, has simple production process, high production efficiency, multiple varieties and specifications and less equipment investment, and generally has lower strength than a seamless steel pipe.

The general welded pipe is of a hollow structure, is sometimes used for an assembly body by a whole section, and is sometimes cut into a plurality of short pipes to be used for the assembly body, but the whole section or the plurality of short pipes are of hollow structures, and the welded pipe is easy to deform when being pressed due to the fact that the welded pipe is not supported by the hollow structure in general, and the welded pipe is assembled on high-end machines such as earthmoving machines, engineering machines and other large-scale machines, although the welded pipe is of a certain strength in the process.

Therefore, in order to solve the problems, the utility model provides a high-strength welded pipe internally welded with multi-bending steel, and the multi-point support effect of the welded pipe body is achieved by internally welding the multi-bending lining steel.

Disclosure of Invention

The utility model mainly solves the technical problem of providing a high-strength welded pipe internally welded with multi-bent steel, which can improve the strength of a welded pipe body and achieve the effect of multi-point support of the welded pipe body by welding multi-bent lining steel through a lining.

In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a high strength welded tube of interior welding multi-turn shaped steel, including the welded tube body, the welded tube body is both ends opening and inside intercommunication's circular pipe, the inside welding of welded tube body inserts multi-turn inside lining shaped steel, multi-turn inside lining shaped steel leading-in length is at least welded tube body length 3/4 and symmetry in welded tube body central point, multi-turn inside lining shaped steel is the shaped steel that the multistage was bent and the shape is arcwall face wavy or V-arrangement zigzag, every summit of multi-turn inside lining shaped steel all with the welding of the inboard pipe wall of welded tube body.

In a preferred embodiment of the present utility model, the bending vertex is an arc surface when the multi-curved lining section steel is in an arc surface wave shape.

In a preferred embodiment of the present utility model, the bent vertex is pointed when the multi-curved lining section steel is in a V-shaped zigzag shape.

In a preferred embodiment of the utility model, the welded pipe body has a diameter greater than 5cm.

The beneficial effects of the utility model are as follows: the utility model can improve the strength of the welded pipe body, achieves the effect of multi-point support of the welded pipe body by welding the multi-bend lining steel through the lining, ensures the compression resistance and the pressure-resistant anti-collision capability of the welded pipe body, can be in the shape of arc-shaped surface wavy lines or V-shaped saw teeth, can achieve good protection effect, and ensures that the welded pipe is not damaged when being pressed, impacted and extruded.
