Problems solved by technology

[0003] At present, the vast majority of outdoor flagpoles are welded and manufactured by pure stainless steel pipes. Not only is the cost high, but also due to the thin wall thickness and low bending strength of pure stainless steel pipes, they are often bent, deformed or even broken after years of wind and rain. It has seriously affected the image of the country and enterprises and institutions, and it is also easy to cause accidents

Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in further detail below through the description of the best embodiment with reference to the accompanying drawings.

[0028] as attached figure 1 As shown, the high-strength stainless steel composite flagpole is made of high-strength stainless steel composite pipe, which is characterized in that it includes a stainless steel composite pipe body 1, a stainless steel composite pipe inner layer Q235 cold-rolled precision welded pipe 2, and a stainless steel composite pipe outer stainless steel thin-walled pipe 3 .

[0029] The high-strength stainless steel composite pipe is made of Q235 cold-rolled precision welded pipe as the base pipe and 304 stainless steel thin-walled pipe on the outside, and is manufactured by axial cold drawing of tungsten steel mold through cold drawing machine.

[0030] as attached figure 2 As shown, the high-strength stainless steel composite flagpole is characterized...

Abstract

The invention relates to a high-strength composite stainless steel flagpole and a welding method thereof. Made of a high-strength stainless steel composite pipe and processed through a special welding process, the high-strength stainless steel flagpole is characterized by comprising a stainless steel composite pipe body 1, a stainless steel composite pipe Q235-innerlayer cold-rolled precision welding pipe 2 and a stainless steel composite pipe outer-layer stainless steel thin-walled pipe 3, and the high-strength stainless steel flagpole is manufactured by cold drawing in a tungsten steel mold via a cold-drawn pipe machine. The high-strength composite stainless steel flagpole and the welding method thereof are further characterized in that the high-strength composite stainless steel flagpole is welded and processed through the special welding process. The high-strength composite stainless steel flagpole and the welding method thereof have the advantages that manufacturing cost can be lowered, bending resistance can be greatly improved, and the flagpole can be kept durable and free of deformation, curves and fracture.

Description

technical field [0001] The application technical field of the stainless steel composite pipe of the present invention, in particular relates to a high-strength stainless steel composite flagpole and its welding method. Background technique [0002] Flagpoles, as the most common outdoor facilities in daily life, are found in factories, schools and party and government agencies. It is a form of propaganda that shows the image of the country and the cultural characteristics of enterprises and institutions. [0003] At present, the vast majority of outdoor flagpoles are welded by pure stainless steel pipes. Not only is the cost high, but also due to the thin wall thickness and low bending strength of pure stainless steel pipes, they are often bent, deformed or even broken after years of wind and rain. It has seriously affected the image of the country and enterprises and institutions, and is also prone to accidents. Contents of the invention [0004] The problem to be solved...
