The performance and function of seamless square tube

Seamless square tube is a kind of hollow steel with rectangular cross-section, made of seamless process, with high strength and excellent performance. Seamless square pipe and welded square pipe have the essential difference, compared with solid steel such as round steel, in the bending and torsional strength is the same, the weight is generally light, is an economic cross-section steel. The following is an introduction to the performance and role of seamless square pipes:

Seamless square tube performance

Seamless square pipe is made of seamless steel pipe by extrusion processing, with excellent physical and mechanical properties, its main characteristics are as follows:

1. High strength and compressive performance: Due to the uniform wall thickness of the seamless square tube and the regular shape of the section, its compressive strength and carrying capacity are much higher than that of ordinary welded square tubes. Can adapt to high loads and complex environments, suitable for vibration and shock applications.

2. Excellent toughness and plasticity: seamless square tube has high toughness and ductility, it is not easy to break during processing, welding and bending, and can maintain good performance even in low temperature environment.

3. Good corrosion resistance: According to the different materials (such as carbon steel, alloy steel, stainless steel), seamless square pipe can have a certain corrosion resistance, especially stainless steel seamless square pipe, suitable for wet and corrosive environment.

4. Good design: the hollow section of the seamless square pipe provides it with the advantages of lightweight structure, which significantly reduces the quality while meeting the strength, which is conducive to reducing the amount of materials and improving the overall economy and construction efficiency.

The role of seamless square tube:

1. Building structure engineering: commonly used in building frame structure, steel structure bridge, scaffolding, etc., to provide good bearing capacity and stability. It is used in high-rise buildings to make beams and columns and steel frame structures to enhance the seismic performance of structures.

2. Machinery manufacturing: widely used in the frame and structural components of mechanical equipment, such as support components of construction machinery, frame support in industrial conveying systems, etc. It can also be used to make major components in agricultural machinery.

3. Transportation: Used to manufacture vehicle frames, ship structural parts, aircraft frames, etc., to provide the dual advantages of strength and weight reduction. It acts as a durable structural support in railway and highway guardrail.

4. Fluid transport and storage: frames for the manufacture of metal furniture, such as office tables and chairs, display shelves, etc., are both decorative and practical. Structural parts in indoor and outdoor decoration projects to enhance visual beauty and practical functions.


Conclusion

Thanks to its high strength, excellent toughness and precise dimensions, seamless rectangular tubes have become indispensable and important materials in the fields of construction, machinery, transportation and decoration. According to the specific use and environmental requirements, different materials and surface treatments can be selected, so that it can provide reliable performance support in a variety of complex conditions.
