Description

Technical Field

[0001] The utility model relates to the field of welded pipes, in particular to a self-fixing welded pipe. Background Art

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after curling and forming. The product is widely used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. It is one of the 20 key products developed in my country. For liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural use: as piling pipes, bridges; docks, roads, building structure pipes, etc.

[0003] However, general welded pipes need to be fixed with fixing parts, and holes need to be punched or cut off on the welded pipes, which damages the overall structural performance of the welded pipes. Moreover, the welded pipes and fixing parts can only be fixed in one direction or one or two positions, and it is difficult to achieve a multi-point and multi-faceted overall fixing method, resulting in loose fixation. In the later stage, the welded pipes may be disconnected or damaged due to impact or pressure.

[0004] Therefore, the utility model provides a self-fixing welded pipe, which can realize stable fixation by itself, and a plurality of reinforcing plates are welded at the end of the welded pipe body to realize a multi-unit fixing mode. Utility Model Content

[0007] In a preferred embodiment of the present invention, the number of fastener connection holes opened on each of the reinforcement layers is a multiple of 4 and is evenly arranged in a ring shape.

[0008] In a preferred embodiment of the present invention, the number of fastener connection holes opened on each of the reinforcement layers is 8 or 12.

[0009] In a preferred embodiment of the present invention, the bottom surface of the reinforcement layer plate at the end of the welded pipe body is flush with the end surface of the pipe opening of the welded pipe body.

[0010] The beneficial effect of the utility model is that the utility model can realize stable fixation by itself, and multiple reinforcing plates are welded at the end of the welded pipe body to realize a multi-body fixing method. The reinforcing plates can be connected and fixed with multiple reinforcing members, or the reinforcing plates can be connected to each other with fasteners to realize different combinations of fixing methods, thereby realizing the firm fixation of the end of the welded pipe body itself, especially when the welded pipe body is used as a vertical support member, so that the welded pipe body has super strong fixing ability.
