How to identify inferior stainless steel welded pipes?
A stainless steel welded pipe, also known as welded pipe, is a type of steel pipe formed by welding common steel or steel strip after it is rolled and shaped using a unit and die. Its manufacturing process is relatively straightforward, resulting in high production efficiency and a wide range of specifications. The investment in equipment is lower compared to seamless steel pipes, but welded pipes generally have lower strength. This article will briefly introduce how to identify inferior stainless steel welded pipes.

How to remove burrs from 304 stainless steel pipes?
In the production of 304 stainless steel pipes, welding is the primary source of burrs. During the welding process, the current is highly concentrated at the weld, causing it to rapidly reach a molten state. As the extrusion rollers apply lateral pressure to the weld, excess metal and oxides accumulate on the upper part, forming burrs on the outer surface. Simultaneously, some excess metal and oxides, under the combined effects of extrusion and gravity, sag along the inside of the pipe, creating internal burrs. These burrs, leftover from the manufacturing process, reduce the quality of the final product. Today, United Steel Industry Co., Ltd. will discuss methods to remove these burrs from 304 stainless steel pipes.
