Hot Sale SCH40 hollow round square tube seamless cold drawn carbon steel pipes pricelist

The manufacturing process of cold-drawn shaped steel usually includes two stages: drawing and rolling. In the drawing stage, the round billet is stretched through a special drawing machine to gradually transform into a steel with a specific cross-section shape. In the rolling stage, the drawn steel is finely rolled by the rolling mill to further improve the dimensional accuracy and surface quality.

The material selection of cold-drawn shaped steel depends on the application requirements and performance requirements. Common materials include carbon steel, alloy steel and stainless steel. Carbon steel has good machinability and mechanical properties and is suitable for most general engineering applications. Alloy steels have higher strength and hardness and are suitable for applications that require greater loads and wear resistance. Stainless steel has corrosion resistance and high temperature stability for applications that require weather resistance and chemical stability.

How to choose seamless steel pipe:

1. Purchased from large conventional steel pipe companies. Regular large companies generally purchase or agent from domestic well-known large seamless steel pipe enterprises, and the quality is guaranteed.

2. Check the product quality certificate issued by the seamless steel pipe manufacturer and the certificate number of the implementation of production license management.

3, choose the right specifications, because the seamless steel pipe used in different fields has different specifications and different functions.

4, choose different processes of seamless steel pipe, because seamless steel pipe can be divided into cold rolled and hot rolled. Different production processes have different steel pipe characteristics and different application fields.

5, the same specification, seamless steel pipe, different manufacturers can refer to, repeated comparison. If it's far below the average, you can't buy it.

6, pay attention to the seamless steel pipe surface is not allowed to have cracks, scars, folding and other defects.

7, manufacturers bulk procurement is the first choice. If you want to wholesale seamless steel pipes, it is best to find other manufacturers directly. After all, you can still enjoy certain benefits without intermediate links and save more expenses.

Advantages of cold drawn seamless steel pipe:

1. High precision: The cold drawing process makes the dimensional accuracy of the special-shaped steel higher and can meet the requirements of various precision applications.

2. Excellent surface quality: cold-drawn special-shaped steel has a smooth surface, without further processing, reducing production costs.

3. Excellent mechanical properties: After the cold-drawing process, the special-shaped steel has high strength, high hardness and good wear resistance, which is suitable for a variety of harsh working environments.

Application: SCH40 square steel tube

1.Structural engineering: Cold-drawn seamless square rectangular pipe is widely used in construction, bridge, mechanical equipment and civil engineering and other fields.
