Problems solved by technology

[0005] Since steel pipes with no weld seams on the surface are basically not in any gaps, the processing technology of steel pipes is strictly required. In the existing process of welding steel pipes, various steel pipes are formed by pickling, heat treatment, grinding and other processes. The actual effect and Production costs are not perfect

Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0024] In this embodiment, the metal pipe is steel pipe 2 as an example, but it may also be copper pipe or metal pipe of other materials, and the present invention is not limited to steel pipe 2 .

[0025] Such as image 3 As shown, the steel pipe 2 is divided into N equal parts, and the reciprocating stroke L of the mandrel 3 is used as the standard for division. The motion stroke L is the same or slightly smaller than L, wherein the Nth part may be smaller than the motion stroke L of the mandrel, depending on the actual length of the steel pipe 2 .

[0026] Such as Figure 4 As shown, after the steel pipe 2 is welded, a weld seam 5 is left, a...

Abstract

The invention relates to a method for producing a metal tube, which comprises the following steps: rolling a metal plate into a metal-tube shape; welding at a rolling seam of the metal plate; and flattening the outside and inside welding seams of the metal tube by pressure. After the metal tube is pressurized, the welding seams of the metal tube are flattened so that the welding seams of the metal tube can not be seen by naked eyes; besides, after being polished in an electrolytic way, the metal tube can be applied in processing devices with high requirements, such as food processing devices, medicine processing devices, and the like.

Description

technical field [0001] The invention relates to a metal pipe processing method, in particular to a stainless steel pipe welding seam removal processing method, and to a stainless steel pipe product produced thereby. Background technique [0002] In the current market, there are many equipment and products that use steel pipes, especially stainless steel pipes, such as food processing equipment, pharmaceutical processing equipment, water heaters, etc. [0003] Common metal pipes, especially steel pipes, are usually rolled into the basic shape of steel pipes with long strips of steel plates, and then welded at the joints of the steel plates to support the steel pipes. Since welding will cause welds to form at the joints of the steel pipes, the inside and outside of the steel pipes will not be smooth, and burrs and gaps will occur on the surface. [0004] For demanding applications, such as food processing equipment, pharmaceutical processing equipment and other products, if t...
