Advantages, disadvantages and applications of seamless square and rectangular tubes

The wave of seamless square tubes and rectangular tubes in the construction industry is getting longer and stronger, and the demand for seamless square and rectangular pipes is also increasing day by day. However, in order to meet production needs and reduce production costs, customers are purchasing original seamless square and rectangular tubes. It is a seamless square rectangular tube. Let us tell you the advantages and disadvantages of its seamless square rectangular tube:

Advantages:
1. Seamless square and rectangular tubes have fast forming speed and high output. It does not damage the coating and can be made into a variety of cross-sections to meet the needs of applicable conditions.
2. The cold rolling process can cause large plastic deformation of seamless square rectangular tubes, thereby increasing the yield point of seamless square rectangular tubes.

3. The high precision of seamless square and rectangular tubes allows users to reduce the generation of waste materials.

Disadvantages:
1. Residual stress exists in the section of the seamless square rectangular tube, which affects the overall and local buckling characteristics of the seamless square rectangular tube;
2. The free torsional stiffness of the section of the seamless square rectangular tube is low;
3. The formed wall thickness of seamless square and rectangular tubes is small and their ability to withstand localized concentrated loads is weak.

Application fields of seamless square and rectangular tubes:
Seamless square and rectangular tubes are widely used in construction, petrochemical industry, machinery manufacturing, medical equipment, automobile manufacturing and other fields. Its main uses include:

1. Construction field: used as building structural materials, such as bridges, tunnels, high-rise buildings, etc.
2. Petrochemical field: used as pipes for transporting oil, natural gas and other pipelines.
3. Machinery manufacturing field: used as mechanical parts, such as car bases, engine exhaust pipes, etc.
4. Medical device field: As a component of medical devices, such as surgical mirror covers, surgical carts, etc.
5. Automobile manufacturing field: As an integral part of the automobile chassis and body frame, such as front struts, rear suspension parts, etc.

In short, seamless square and rectangular tubes have a wide range of applications and are an indispensable material for modern production and construction.
