Rectangular tube production process

Posted by BAOWI STEEL MANUFACTURING CO.,LTD on April 18th, 2024

The production process of rectangular tubes involves many aspects, including raw material preparation, processing technology, forming process, inspection and packaging. The following is a rough introduction to the production process of rectangular tubes:

1. Raw material preparation

The main raw material of rectangular tubes is usually steel plate or aluminum plate. In the production process, raw materials need to be prepared first, including the following steps:

Material selection: According to product requirements and customer needs, select steel plates or aluminum plates of appropriate specifications and materials as raw materials.

Material cutting: Use shears and other equipment to cut raw materials and cut them into plates of corresponding sizes according to design requirements.

2. Processing technology

The processing technology of rectangular tube mainly includes the following steps:

Bending and forming: The plate is bent and formed by a pipe bending machine or a plate bending machine to give it the shape of a rectangular tube.

Welding: Butt the bent and formed plates, and use resistance welding, gas shielded welding and other methods to weld to ensure that the joints are firm.

Trimming: trim and polish the welding joint to ensure a smooth surface.

3. Molding process

The forming process of rectangular tubes includes the following steps:

Roll forming: Use a roller forming machine to roll the welded rectangular tube to make it smoother and remove the unevenness of the inner and outer walls.

Straightening: Straighten the rolled rectangular pipe to ensure that the straightness and shape of the pipe meet the requirements.

4. Inspection and packaging

Rectangular tubes require strict inspection during the production process to ensure that product quality meets standard requirements:

Appearance inspection: Inspect the appearance of the rectangular tube, including whether the surface is smooth and has no obvious scratches and deformations.

Dimensional inspection: Use measuring tools to inspect the dimensions of rectangular tubes to ensure accurate dimensions.

Chemical composition analysis: Conduct chemical composition analysis on the material of the rectangular tube to ensure that it meets relevant standards.

Finally, the rectangular tubes that pass the inspection are packaged. Common packaging methods include plastic film packaging, wooden box packaging, etc. to ensure that the product is not damaged during transportation.

This is just a simple overview of the rectangular tube production process. The actual production process may involve more details and process links, which need to be adjusted and improved according to specific circumstances.
