Mild Steel Tube - Square Tube

Mild steel tube refers to a carbon steel pipe with a carbon content of less than 0.25%. Square ms tube is a commonly used pipe material at present. Its main characteristics are good plasticity, weldability and machinability, and it exhibits good mechanical properties and corrosion resistance.

Production process

1. Raw material processing,

The main raw material for producing square mild steel tube is low carbon steel. These raw materials need to be processed by hot rolling, cold rolling and other processes to remove impurities and improve their mechanical properties.

2. Forming

The steel billet is cut into a length and width suitable for the production of square tubes by a cutting machine. Then, the steel billet is pressed into a square tube using a mold, which is called "forming".

3. Welding and surface treatment

During the welding process, it is necessary to ensure the quality of the square tube to prevent cracks or defects. Surface treatment includes polishing, painting, etc. to increase the aesthetics and corrosion resistance of the square tube.

Specifications and dimensions

The specifications and dimensions are mainly as follows:

1. Square tube outer diameter: 10mm×10mm~600mm×600mm

2. Square tube wall thickness: 0.5mm~20mm

3. Square tube length: generally 6 meters, can also be customized according to user requirements.

Characteristics of square mild steel tubes

Mild steel square tubes have good weldability, plasticity and processability, and can be widely used in construction, machinery manufacturing, automobile manufacturing, aerospace and other fields. Its main features are as follows:

1. Excellent mechanical properties

Square mild steel tubes have good toughness and ductility, high strength, wear resistance, light weight, and corrosion resistance, which can meet the use requirements of various projects.

2. Easy to process

Square mild steel tubes can be processed by cutting, cold bending, welding and assembly. The processing technology is simple, the cost is low, and it can be used repeatedly, which is suitable for various engineering designs.

3. Environmental protection and energy saving

Square mild steel tubes do not require heat treatment during production, nor do they contain harmful pup jointstances. They meet environmental protection requirements and have high economic benefits.

4. Smooth and beautiful surface

The color is smooth, the surface finish is high, and it has a good look. It can not only meet the requirements of structural parts, but also have a good decorative effect.

Application areas of square mild steel tubes

1. Construction industry

Square mild steel tubes can be used as support and skeleton materials for building structures such as bridges, tunnels, underground passages, houses and factories, and can also be used as decorative materials such as guardrails, stairs and railings.

2. Machinery manufacturing

It can be used in the manufacturing of machine parts, bicycle frames and other manufacturing fields.

3. Transportation field

Square mild steel tubes can be used as manufacturing materials for automotive parts such as frames, baffles, fuel pipes and exhaust pipes, and can also be used in the construction of rail transportation, such as: pup jointway track support and tunnel structure.

4. Aerospace

It can be used in aircraft, satellite aerospace components and other fields.

5. Chemical industry

Square mild steel tubes can be used as OCTG pipe materials, chemical pipeline materials, equipment materials, etc.

Precautions for the use of square mild steel tubes

1. Load-bearing capacity verification

When using square mild steel tubes, attention should be paid to the limit of their bearing capacity to avoid safety accidents during use.

2. Anti-rust treatment

When using square mild steel tubes, attention should be paid to the anti-rust treatment of the pipes to ensure their service life and safety.

3. Standard installation

When installing square mild steel tubes, attention should be paid to installing them according to their use specifications, and appropriately strengthening support and fixation.

Conclusion

Square mild steel tubes are a widely used pipe material with a variety of specifications and standards, suitable for construction, machinery, automobiles, aerospace and other fields. When using square mild steel tubes, attention should be paid to their load-bearing capacity, anti-rust treatment and correct installation methods to ensure their safety and service life.
