How Is Seamless Square Or Rectangular Tube Manufactured?

With the continuous development of modern industry, the requirements for the performance of pipe materials are also constantly increasing. In modern industry, seamless square or rectangular tube has become an important pipe materials due to its advantages of stable structure, easily processing, and precise dimensions, etc. It is widely used in the fields of buildings, machines, and automobiles, etc. So How is seamless square or rectangular tube manufactured?

Round tube to Square or Rectangular tube

Seamless square or rectangular tube is formed by rolling round tubes through a mold. This type of pipe material not only retains the advantages of round tubes, but also has the characteristics of structural stability and excellent load-bearing capacity, etc.

Manufacturing process of Square or Rectangular tube

1. Preparing raw materials: Select suitable round seamless steel pipe as the raw material to ensure the chemical composition and mechanical properties of steel tubes.

2. Cold drawn forming: Round tubes are gradually extruded or stretched into square or rectangular by using forming molds. This process requires precise control the shape, dimension, and extrusion speed of the mold to ensure that the formed square or rectangular tube has precise dimensions and smooth surface.

3. Finishing and Inspection: Formed square or rectangular tube should be finished (such as cutting, polishing, and straightening, etc.) to reach the standard.

4. Inspection: After the production of square or rectangular tube is finished, all tubes shall be inspected to ensure conformance to the requirements of the standard.
