Hollow tube manufacturing process

The process of making hollow tubes usually includes the following steps:

Material preparation. According to the application scenario and design requirements of the required hollow pipe, select the appropriate material, such as aluminum alloy, stainless steel, copper, steel, etc.
Open materials. Use a tool such as a cutter to cut the selected material to the desired length and width.
Annealing treatment. The material is annealed to reduce internal stress and improve the material's strength and wear resistance.
Punching and bending. The cut material is punched to form holes of the required shape and size, and then the material is formed into a hollow tube through bending machinery or hydraulic bending.

welding. Welding is often required during the production process of hollow pipes. Welding methods include TIG welding, MIG/MAG welding, manual arc welding, etc., depending on the characteristics and requirements of the material.
Surface treatment. After welding is completed, the hollow pipe is subjected to surface treatment, such as rust removal, painting, etc., to improve the appearance quality and prevent rust.
In addition, there are other methods for making hollow tubes, such as extrusion, drawing, rotational molding, etc. These methods are suitable for manufacturing hollow tubes of different shapes and sizes.
