Stainless steel round tubes are hollow circular cross-section tubes, divided into two main categories: seamless round tubes and welded round tubes. They are made from stainless steel raw materials such as 201, 304, 304L, 316, 316L, 321, and 430, and are manufactured through processes such as hot rolling, cold drawing, coil welding, polishing, and finishing.

Stainless steel square tube is a hollow long steel material. It is called a square tube because its cross section is square. They are widely used as pipelines for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, they are lighter in weight when the bending and torsional strength are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures.

Stainless steel rectangular tubes are a type of shaped tube, specifically a hollow, long strip of steel. Compared to round tubes, shaped tubes (such as rectangular tubes) generally have a larger moment of inertia and section modulus, resulting in greater bending and torsional resistance. This allows for weight reduction in structures and the saving of steel.

201 stainless steel pipe is a welded steel pipe made of 201 stainless steel, which has the characteristics of good corrosion resistance, high density, polishing without bubbles, etc. It is widely used in decorative pipes, industrial pipes and some shallow drawing products, such as building decoration, furniture manufacturing, tableware and other fields. Although its corrosion resistance is slightly inferior to 304 stainless steel, it still has a place in the market with its lower cost and good processing performance.

304 stainless steel pipe is a high-performance pipe made of high-quality 304 stainless steel. It has a smooth surface, compact structure, wide diameter range, adjustable thickness, excellent corrosion resistance and high temperature resistance, and can withstand greater pressure and impact. 304 stainless steel welded pipe is easy to process and weld, and can be used in many fields such as petrochemical, food processing, building water supply and drainage, machinery manufacturing, etc., showing wide applicability and superior performance.

316 stainless steel pipe is a high-quality pipe material made of 316 stainless steel by double-sided submerged arc welding process. It is rich in chromium, nickel, molybdenum and other elements, has excellent corrosion resistance and heat resistance, and is particularly suitable for marine environments or chloride-containing media. At the same time, 316 stainless steel welded pipe has good welding performance and physical properties such as compressive strength. It is widely used in petroleum, chemical, medical, food, construction and other fields, and is a high-quality steel pipe that is resistant to pressure and corrosion.

321 stainless steel pipe is a high-performance pipe material containing titanium and has excellent high temperature resistance and corrosion resistance. It can maintain excellent performance for a long time at high temperature and has strong corrosion resistance, and is suitable for a variety of corrosive environments. 321 stainless steel welded pipe has high strength, good durability, easy welding, and good weld toughness and ductility. Therefore, it is widely used in petrochemical, food processing, aerospace and other fields, becoming an indispensable key material in these industries.

420 stainless steel pipe is a high-quality pipe material made of 316 stainless steel by double-sided submerged arc welding process. It is rich in chromium, nickel, molybdenum and other elements, has excellent corrosion resistance and heat resistance, and is particularly suitable for marine environments or chloride-containing media. At the same time, 316 stainless steel welded pipe has good welding performance and physical properties such as compressive strength. It is widely used in petroleum, chemical, medical, food, construction and other fields, and is a high-quality steel pipe that is resistant to pressure and corrosion.

304L stainless steel pipe is a high-quality seamless steel pipe made of 304L stainless steel. This steel pipe has excellent corrosion resistance and can resist the erosion of various chemical media. It is particularly suitable for occasions where acidic and alkaline substances are handled. At the same time, it has good welding and processing properties, is easy to cut, bend and weld, and can meet the use requirements of different fields. 304L stainless steel seamless pipe also has high strength and toughness, and can withstand high pressure and load. Due to its unique properties, it is widely used in many fields such as chemical industry, food processing, medical treatment, aerospace, etc.
