How does seamless steel pipe perform in extreme temperatures?
Seamless steel pipes are high-quality rolled pipes that are free of welds. They are manufactured using various processes, including hot extrusion, cold pressing, oblique punching, cold rolling, pressing, and cold drawing. Common types of seamless steel pipes include high-pressure pipes for boilers, pipes for fertilizers, and alloy structural steel pipes. Due to their hollow cross-section, seamless steel pipes are widely used in fluid transport systems, such as those for oil and natural gas, as well as in the manufacture of structural and mechanical components like oil drill pipes and automobile transmission shafts.

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.
