Square tube processing technology

The processing technology of square tubes includes blanking, edge making, forming, welding, straightening, trimming, hair removal, rust prevention and other links. The first step is to cut the raw material steel plate or steel coil according to the required size to obtain a square tube of the required length. During the edge making process, the edges of the square tubes are processed through cutting, grooving, edging and other processes to ensure the flatness and dimensional accuracy of the edges.

In addition to the above processing technology, square pipes also need to be rust-proofed to extend their service life. Common anti-rust methods include spraying anti-rust paint, hot-dip galvanizing, chrome plating, etc. Spraying anti-rust paint is to spray a layer of anti-rust paint on the surface of the square pipe to isolate the air and water and prevent the square pipe from rusting. Hot-dip galvanizing is to immerse square pipes in molten zinc liquid to form a layer of zinc to prevent rust. Chrome plating is to coat the surface of the square tube with a layer of chromium to improve the corrosion resistance of the square tube.

The following points should be noted during the processing of square tubes

1. Strictly control the processing size and tolerance to ensure the dimensional accuracy of the square tube

2. Pay attention to protecting the surface of the square tube during processing to avoid scratches or damage

3. Conduct a comprehensive inspection of the welded joints to ensure the quality and strength of the welds

4. According to the different uses of square tubes, choose the appropriate material and processing technology.

The processing technology of square tubes is crucial to the quality and performance of the products. Only through scientific and reasonable processing technology can square tube products with excellent quality and precise dimensions be produced. At the same time, during the processing, attention should be paid to protecting the surface of the square tube to prevent damage and rust.
