In the machinery manufacturing industry, there are many methods for forming thick-walled seamless tubes, but few processes truly benefit enterprises in terms of efficiency, cost, and quality.

The national standard thickness of stainless steel pipes should first be determined by the nominal diameter or outer diameter of the pipe.

In automobiles, there's a material that may go unnoticed, but it's crucial—like the car's "blood vessels" and "skeleton," supporting the powertrain and ensuring safety.

304 stainless steel pipes are well known for their durability and resistance to corrosion, but they are not completely immune to rust. If they are handled or stored carelessly, rust spots can still appear.

Cold-rolled seamless steel tube, also known as precision seamless steel tube, is a high-precision steel tube produced using a cold-rolling process. Its outer diameter ranges from 4.0 to 450 mm, and its wall thickness from 0.04 to 60 mm, conforming to standard GB/T3639-2008.

API 5L pipelines are widely used for transporting oil, natural gas, water, and for the natural gas industry. API 5L refers to the American Petroleum Institute's standard, which is prepared and issued worldwide.
