Production process of square tube


square tube


Large square tube is a common steel tube product, widely used in construction, machinery manufacturing, automobile manufacturing and other fields. Seamless square tube is a common square steel tube. Its production process is similar to that of seamless steel pipe, but it has its own unique characteristics.

The production process of seamless square tube will be introduced in detail below.


1. Preparation stage


The main raw material for producing square tube is low carbon steel or low alloy steel. In the raw material preparation stage, the raw materials need to be inspected and classified, high-quality steel plates need to be selected, and strict quality inspections need to be carried out to ensure that the raw materials meet the relevant standards and requirements. At the same time, the square steel needs to be straightened and polished to ensure that its surface is smooth and defect-free.


2. Cutting stage


In the cutting stage, the square steel needs to be cut to the required length, which is a key step in production. Advanced equipment and technology need to be used to ensure the precise size and shape of the pipe. When cutting, attention should be paid to maintaining the flatness and verticality of the cut section to ensure the accuracy of subsequent processing.


3. Forming stage


In the forming stage, the cut square steel needs to be bent and formed. Professional forming equipment, such as hydraulic forming machine or mechanical forming machine, is required in this process to ensure that the shape and size of the square steel meet the requirements.


4. Sizing stage


During the sizing stage, the diameter and roundness of the formed square steel need to be adjusted. Professional sizing equipment, such as sizing machines or straightening machines, are required in this process to ensure that the diameter and roundness of the square steel meet the requirements.


5. Heat treatment stage


During the heat treatment stage, the square steel needs to be heated, insulated and cooled to improve its mechanical properties such as strength and hardness. The heat treatment method can be selected according to different materials and requirements, such as quenching, tempering, carburizing, etc.


6. Surface treatment stage


During the surface treatment stage, the square steel needs to be surface treated to improve its corrosion resistance and aesthetics. The surface treatment method can be selected according to different requirements, such as shot peening, painting, galvanizing, etc.

7. Inspection stage


During the inspection stage, the square steel needs to be inspected for appearance and size to ensure that it meets the requirements. If defects or dimensional deviations are found, repairs or adjustments are required.


8. Packaging stage


During the packaging stage, the qualified square steel needs to be packaged to protect its surface from damage and contamination. The packaging method can be selected according to different requirements, such as wooden frame packaging, carton packaging, etc.


In summary, the production process of seamless square tubes includes preparation stage, cutting stage, forming stage, sizing stage, heat treatment stage, surface treatment stage, inspection stage and packaging stage. Each stage has its specific requirements and operation methods, and it is necessary to strictly follow the process requirements to produce high-quality seamless square tubes.
