The production process of large-diameter straight seam welded pipes is simple and the production efficiency is high. However, the strength of large-diameter spiral welded pipes is generally higher than that of straight seam welded pipes. They can produce welded pipes with larger diameters using narrower billets, and can also produce welded pipes and frame pipes with different diameters using billets of the same width. However, the production efficiency is lower compared to straight seam steel pipes. Large caliber welded pipes are mainly used in large-scale pipeline engineering, water and gas transmission engineering, urban pipeline construction, municipal engineering, water supply and drainage engineering, large building steel structures, pile foundations, and other fields.

In order to improve the durability and corrosion resistance of seamless steel pipes, anti-corrosion treatment is usually carried out during the production process. One common treatment method is hot-dip galvanizing or spraying anti-corrosion coatings. When the sprayed coating is black or contains black components, the surface of the steel pipe will appear darker. This anti-corrosion treatment not only enhances the durability of steel pipes, but also provides better protection in high temperature, humid or corrosive environments.

Seamless square tube is a long steel strip with a hollow cross-section and no seams around the periphery. The tube is hollow and has a certain cross-sectional area. Circular tubes have certain limitations, such as lower bending strength than square and rectangular tubes under flat bending conditions. Some agricultural machinery skeletons, steel and wood furniture, etc. commonly use square and rectangular tubes.

Square rectangular pipe is a term for square and rectangular pipes, which refers to steel pipes with equal or unequal side lengths. It is rolled from strip steel through process processing. Generally, the strip steel is unpacked, flattened, curled, and welded into circular tubes, which are then rolled into square tubes and cut to the required length.
